CROSS REFERENCE TO RELATED APPLICATION 
   This application is based on Japanese Patent Application No. 2001-176383, filed on Jun. 11, 2001, the entire contents of which are incorporated herein by reference. 
   BACKGROUND OF THE INVENTION 
   A) Field of the Invention 
   The present invention relates to a recording/reproducing apparatus for recording digital audio data in an external storage unit such as a hard disk and reproducing it by a multi-track method. 
   B) Description of the Related Art 
   A digital mixer converts audio data of an input analog signal into digital data or directly inputs digital audio data and mixes digital audio data for output. A digital recorder records and reproduces digital audio data in an external storage unit such as a hard disk. A multi-track digital recorder is known as one type of the digital recorder that can record a plurality series of audio data into a plurality of tracks. An apparatus that features the functions of both a digital mixer and a multi-track digital recorder is available nowadays. 
   Some apparatus having features of both a digital mixer and a multi-track digital recorder can patch (selectively wire) each signal to be input into each input channel. With this patch function, a plurality of analog input signals, a plurality of digital input signals, and a plurality of input signals from internal samplers, external effectors and the like can be assigned to desired input channels of a digital mixer. Some apparatus can set the output bus of each input channel or a direct output of each input channel. With this function, input signals to the input channels of the digital mixer can be set to be output to a plurality of mixing buses such as mixing buses and stereo buses or to be output directly without mixing. A directly output signal or an output signal from a bus such as a mixing bus can be assigned to a desired record track of the digital recorder. 
   Since a plurality of input signals and recording channels are patched, patch settings for recording input signals require much labor. To avoid this, some apparatus is provided with a quick record setting (quick REC) function of facilitating a patch of input signals if they are recorded without being mixed with other signals.  FIG. 13  shows a quick REC window displayed when an operator unit is manipulated in a predetermined manner. By using this window, a plurality of input channels, routing and a plurality of tracks can be set collectively so as to match initial recording. 
   Referring to  FIG. 13 , INPUT CH  1301  represents an input signal. For example, analog inputs of eight channels, inputs of eight channels of cards entered into slots and other inputs can be selected. In MIXER CH  1302 , two blocks of mixer channels # 1  to # 8  and mixer channels # 9  to # 16  of the digital mixer are displayed in a fixed state. Similarly, in REC TR  1303 , two blocks of record track numbers # 1  to # 8  and record track numbers # 9  to # 16  are displayed in a fixed state. The blocks of MIXER CH and REC TR cannot be changed by using an operator unit. 
   By properly setting INPUT CH  1301  and clicking EXECUTE  1304  shown in the window, an input patch is established so that each input displayed in INPUT CH  1301  is input to each input channel displayed in MIXER CH  1302 . 
   An output of each channel displayed in MIXER CH  1302  is directly input to each track of an internal recorder displayed in REC TR  1303 . 
   With this quick REC function, settings are performed in the unit of eight input channels and eight tracks so that flexible settings are difficult. For example, if signals have already been recorded in the track # 2  and new signals are to be recorded in other tracks without erasing the track # 2 , it is necessary to first perform the quick REC settings for the tracks # 1  to # 8  and thereafter designate the track # 2  as non-record. 
   Also with the quick REC function, it is impossible to change an input signal to an input channel. Namely, it is necessary to assign an input signal to an input channel by using another setting window before or after the quick REC setting. 
   Also with the quick REC function, it is necessary to perform initial settings (initial characteristics settings) of a compressor, equalizer, fader and the like of each input channel. These initial settings are performed in order to avoid an unpleasant event. For example, if the fader was enhanced or the compressor was set greatly immediately before the quick REC settings, recording in this state without readjustment results in recording with improper inputs. 
   However, there is a need for performing recording with the input channel conditions adjusted immediately before the quick REC settings. The specification of the quick REC function does not satisfy such a need.

   DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     FIG. 1  is a block diagram showing the overall structure of a multi-track digital recording/reproducing apparatus having a mixing function according to an embodiment of the invention. This apparatus has a display unit  101 , a fader  102 , an operator unit  103 , a CPU  104 , a flash memory  105 , a random access memory (RAM)  106 , an input/output (I/O) interface  107  to and from a personal computer, a hard disk (HD)  108 , a transfer circuit  109 , a buffer memory  110 , a digital signal processor (DSP)  111 , and a bus line  122 . External connection terminals include an analog input (AD)  112 , a digital input (Din L/R)  113 , slots (SL)  114  and  115 , an analog output (Aout L/R)  118 , a digital output (Dout L/R)  119 , an omni-output (OMNI)  120 , and an external effector (EE)  121 . 
   The analog input (AD)  112  is constituted of eight analog audio data input terminals. Analog audio data input to the input terminals is converted by an analog-digital converters (not shown) and input to DSP  111 . The digital input (Din L/R)  113  is constituted of digital audio data input terminals of stereo two channels. The analog output (Aout L/R)  118  is constituted of external terminals for converting outputs of stereo two channels from DSP  111  into analog signals and outputting the analog signals. The digital output (Dout L/R)  119  is constituted of digital output terminals of stereo two channels of digital audio signals from DSP  111 . The omni-output (OMNI)  120  is constituted of digital data output terminals of four channels of digital audio data from DSP  111 . The external effector (EE) input  121  is constituted of input terminals of stereo two channels each having two series (four channels in total) of data from an external effector. 
   The slots (SL)  114  and  115  are constituted of two expansion slots mounted on the apparatus. Various types of option cards can be inserted into the expansion slots.  FIG. 1  shows an example of a card  116  inserted into the expansion slot  114  and a card  117  inserted into the expansion slot  115 . For example, the cards  116  and  117  are an analog—digital converter card for analog input, a digital I/O card, a digital —analog converter card for analog output and the like. By inserting these cards into the slots  114  and  115 , it is possible to increase the number of input/output terminals for external connections. An input card capable of receiving eight channels at a maximum can be inserted, and an output card capable of outputting eight channels at a maximum can be inserted. 
   The display unit  101  is a display such as a liquid crystal display for displaying various information. The fader  102  is an operator unit of a slide volume type capable of adjusting the level of an input or output channel assigned as desired. The operator unit  103  includes various types of switches. CPU  104  controls the whole operation of the apparatus. The flash memory  105  stores control programs and the like to be executed by CPU  104 . RAM  106  is used for an area in which programs stored in HD  108  are loaded to be executed by CPU  104 , and for a working area. The I/O interface  107  to and from a personal computer (PC) is used for connection to PC. The hard disk (HD)  108  is an external storage unit for storing programs to be executed by CPU  104  and various data, and has a digital audio data record area. The buffer memory  110  temporarily stores recording/reproducing data when recording/reproducing is performed by using HD  108 . The digital signal processor (DSP)  111  performs an audio data mixing process, an effect adding process and the like. 
   The transfer circuit  109  controls a data transfer  131  between HD  108  and buffer memory  110  and a data transfer  132  between DSP  111  and buffer memory  110  in accordance with an instruction from CPU  104 . Recording/reproducing by HD  108  is performed by a multi-track method (track is a concept of series for audio data recording/reproducing and is different from a physical record area track concentrically disposed on the disk of HD). The fundamental operation of the transfer circuit  109  for one track recording is to receive record data of one sample from DSP at each sampling period and write it in the buffer memory  110 , and to transfer samples of one cluster loaded in the buffer memory to a corresponding track record area of HD  108 , an operation of receiving and writing record data continuing during the transfer operation. The fundamental operation of the transfer circuit  109  for one track reproducing is to read samples of top two or more clusters of the track from HD  108  and write them in the buffer memory, to read one sample from the buffer memory  110  at each sampling period and transfer it to DSP  111 , and when an empty area (buffer area of already reproduced samples) of one cluster is formed in the buffer memory, to transfer data of the next cluster to the empty area from HD  108 . 
   The cluster is a minimum logical unit for data read/write of HD  108 .  FIG. 2  is a diagram showing the panel of the apparatus shown in  FIG. 1 . On this panel, the display unit  101 , fader  102  and operation unit  103  shown in  FIG. 1  are mounted. A display  201  corresponds to the display unit  101  shown in  FIG. 1 . Reference numeral  210  represents a shift key, and reference numerals  211  to  215  represent F1 to F5 keys. Reference numeral  221  represents cursor motion keys for moving a cursor displayed on the display  201 , and reference numeral  223  represents an enter key. Reference numeral  222  represents a value input operator unit (data input dial) for setting or changing a value of various data. 
   Operator sets  231 - 1  to  231 - 16  are assigned to mixer input channels and control the corresponding mixer input channels, as will be described later. 
   The mixer input channel is an input series to a mixing bus. There are twenty four channels from the mixer input channel # 1  to mixer input channel # 24 , the details of the mixer input channel be given later with reference to  FIG. 3 . A SEL key  232  of the operator set  231 - 1  is used for displaying a window of the mixer input channel to perform various settings (frequency characteristics adjustment, control of the compressor, panning and the like). An ON key  233  is used for switching between on/off of the mixer input channel. A fader operator unit (of a slider volume type)  234  is used for adjusting the volume level of the mixer input channel. The SEL key  232  and ON key  233  are toggle switches which emit light when they are depressed and enter a select state, and extinguish light when they are again depressed and enter a non-select state. When a  1 - 16  channel select key  261  is depressed, the operator set  231 - 1  is assigned to the mixer input channel # 1  and can control the mixer input channel # 1 . When a  17 - 24  channel select key  262  is depressed, the operator set  231 - 1  is assigned to the mixer input channel # 17  and can control the mixer input channel # 17 . In order to indicate this, numerals “ 1 ” and “ 17 ” are printed on the panel above the operator set  231 - 1 . 
   On the right side of the operator set  231 - 1 , similar operator sets  231 - 2  to  231 - 16  are mounted. Numerals printed above each operator set indicate the mixer input channels to be controlled by the operator set when the 1-16 channel select key  261  or 17-24 channel key  262  is turned on. Above the operator sets  231 - 15  and  231 - 16  for controlling the mixer input channels # 15  and # 16 , “RTN 1 ” and “RTN 2 ” are printed under the numerals “ 15 ” and “ 16 ”. This means that when the  17 - 24  channel selection key  262  is turned on, these operator sets  231 - 15  and  231 - 16  are allocated as the operator sets for controlling two effect return channels  313  shown in  FIG. 3 . An operator set  241  is used for controlling the final outputs of stereo two channels. 
   When a SOLO key  264  is turned on (when the key top of the SOLO key illuminates) and one of the ON keys  233  of the channels is turned on, only sounds of this channel are output. A REW key  251 , an FF key  252 , a PLAY key  253 , a REC key  254 , a PAUSE key  255  and a STOP key  256  are used for rewind, fast forward, play, record, pause and stop, respectively. 
   Record track switches  263  are used for selecting a record track. By turning on one of the record track switches labeled “ 1 ” to “ 16 ”, the track having the corresponding track number becomes recordable. By turning on a SETUP key  265 , an input/output patch to be described later becomes settable. By turning on a RECORDER key  266 , it is possible to perform adjustments of the frequency characteristics and volume level (by the fader) and controls of the compressor, panning and the like (by SEL keys) by using the operator sets  231 - 1  to  231 - 16  shown in  FIG. 2 , with respect to recorder channels  320  to be described later with reference to  FIG. 3 . By turning on a QUICK REC key  267 , a QUICK REC window to be described with reference to  FIG. 6  and following Figures is displayed to facilitate a plurality of assignment operations. 
     FIG. 3  is a block diagram showing the outline of a mixing process to be realized by DSP  111 . AD  301  represents signals of eight channels converted into digital signals and input from the analog input (AD  112  shown in  FIG. 1 ). SLin  302  and  303  represent inputs from input option cards inserted into the two slots (SL  114  and  115  shown in  FIG. 1 ). A card capable of receiving eight channels at the maximum can be inserted into the slot. Inputs of sixteen channels can be received by using two slots. Din L/R  304  represents digital inputs (Din L/R  113  shown in  FIG. 1 ) of stereo two channels. 
   An internal sampler  305  inputs signals of eight channels from an unrepresented internal waveform memory tone generator. The waveform of any musical tone can be stored in each channel of the internal waveform memory tone generator. By depressing a predetermined switch, the musical tone can be generated at any time desired. For example, effects sounds such as sounds of clapping of hands may be stored and generated when necessary. 
   EF  306  (EF  121  shown in  FIG. 1 ) inputs signals of stereo two channels from an unrepresented external effector (effect adding apparatus). In the recording/reproducing apparatus, digital data picked up from AUX buses of channels # 1  to # 6  to be described later can be input to an external effector to add effects and the digital audio data with the added effects can be returned back to the input side. EF  306  inputs such effects signals. DSP  111  may function in  FIG. 3  as an unrepresented internal effector. This internal effector can add effects to digital audio data picked up from the channels # 7  and # 8  of AUX buses, and the digital audio data with the effects can be returned back to the input side. 
   Aout L/R  331  represents analog outputs of stereo two channels (Aout R/L  118  in  FIG. 1 ). Dout L/R  332  represents digital outputs of stereo two channels (Dout L/R  119  in  FIG. 1 ). SLout  333  and  334  represent outputs of data from option cards inserted into the two slots. Since a card capable of outputting eight channels at the maximum can be used, sixteen channels at the maximum can be output by using the two slots. OMNI  335  represents digital outputs of four channels (OMNI  120  in  FIG. 1 ). 
   General buses (for recording and reproducing)  314  of eight channels are represented by BUS 1  to BUS 8 . Recording/reproducing buses  315  of stereo two channels are represented by Stereo_L/R. Solo buses (for reproducing)  316  of stereo two channels are represented by Solo_L/R. AUX buses (for recording and reproducing)  317  are represented by AUX 1  to AUX 8 . These buses are mixing buses. 
   Mixer channels  312  represent input series to the mixing buses  314  to  317  for mixing. There are twenty four mixer input channels  312  to which the operator sets  231 - 1  to  231 - 16  are allocated to perform adjustments of the frequency characteristics and volume level (by the fader shown in  FIG. 2 ) and controls of the compressor, panning and the like (by the SEL keys shown in  FIG. 2 ). 
   As indicated by arrows to the mixing buses  314  to  317  in  FIG. 3 , each mixing input channel can be selectively connected to any one of the mixing buses. A signal of each mixer input channel whose level was controlled by the fader can be selectively output to any one of eight general buses BUS 1  to BUS 8  and two Stereo_L/R buses for stereo recording. A signal of each mixer input channel before the level is adjusted can be output to two Solo_L/R buses. A signal of each mixer input channel whose level and AUX level were controlled can be output to the eight AUX buses AUX 1  to AUX 8 . Of the twenty four channels, the first sixteen channels are provided with direct-outs for directly inputting signals to sixteen tracks of an internal recorder. Arrows from the mixer input channels  312  to a record selector  318  to be described later correspond to the direct-outs. In the direct-outs, a signal is input from the n-th input channel to the n-th track in one-to-one correspondence. A signal of each mixer input channel can be output via an output patch  321  to be described later to any one of output terminals  331  to  335 . 
   The effect return channels  313  are two-channel series for return signal inputs from an external or internal effector. The channels are assigned the operator sets  231 - 15  and  231 - 16  described with reference to  FIG. 2  so that it is possible to perform adjustments of the frequency characteristics and volume level (by the fader shown in  FIG. 2 ) and controls of the compressor, panning and the like (by the SEL keys shown in  FIG. 2 ). As indicated by arrows from the effect return channels  313  to the mixing buses  314  to  317  shown in  FIG. 3 , each of the effect return channels can be connected to any one of the mixing buses. 
   Each of the mixer input channels  312  and effect return channels  313  can be selectively assigned one of thirty eight inputs including the thirdy maximum external inputs ( 301  to  304 ,  306 ) and the eight internal inputs ( 305 ). The input patch  311  is a mechanism of performing such assignment. The window to be used for the assignment by the input patch  311  will be later described with reference to  FIG. 4 . 
   An HD recorder  319  is an internal recorder capable of recording/reproducing sixteen tracks. Each track can be selectively input with a record signal from one of thirty four buses including the eight general buses BUS 1  to BUS 8 , sixteen direct-outs from the mixer input channels  312 , two stereo recording/reproducing buses Stereo_L/R and eight AUX buses AUX 1  to AUX 8 . This assignment is performed by the record selector  318 . A window to be used for the assignment by the record selector will be later described with reference to  FIG. 4 . This assignment can be performed more easily on windows to be described with reference to  FIG. 6  and following Drawings by turning on the QUICK REC key  267 . 
   A reproduced output of each track of the HD recorder  319  is supplied to the recorder channels  320 . There are sixteen recorder channels in correspondence with the sixteen tracks of the internal recorder. By turning on the RECORDER key  266  shown in  FIG. 2 , it is possible with respect to an input signal of each recorder channel  320  to perform adjustments of the frequency characteristics and volume level (by the fader shown in  FIG. 2 ) and controls of the compressor, panning and the like (by the SEL keys shown in  FIG. 2 ). Each recorder channel is supplied with a record input of the corresponding track (if data reproduced from the HD recorder  319  is supplied again via BUS to the HD recorder) or with a reproduced output of the corresponding track. A signal of each recorder channel  320  whose level was controlled by the fader can be selectively output to one of the eight general buses BUS 1  to BUS 8  and two stereo record buses Stereo_L/R. A signal of each recorder channel  320  before the level is controlled can be output to one of the two solo buses Solo_L/R. A signal of each recorder channel  320  whose level and AUX level were controlled can be output to one of the eight AUX buses AUX 1  to AUX 8 . 
   Data from each of the mixing buses  314  to  317  and mixer input channels  312  can be selectively output to each of the output terminals  331  to  335 . This assignment is performed by the mechanism of the output patch  321 . A window to be used for the assignment by the output patch  321  will be later described with reference to  FIG. 5 . 
     FIG. 4  shows an example of a window to be used for the assignments by the input patch  311  and record selector  318 . This window is displayed when the SETUP key  265  shown in  FIG. 2  is turned on. 
   In  FIG. 4 , a MIXER CHANNEL INPUT ASSIGN area  401  is used for designating which inputs  301  to  306  are assigned to the mixer input channels # 1  to # 24  and effect return channels. Numerals “ 1 ” to “ 24 ” represent the mixer input channels # 1  to # 24 , and the assigned inputs are shown under the numerals as “AD 1 ”, “AD 2 ”, . . . , “SL 1 - 1 ”, . . . , “SL 2 - 1 ”,. . . “AD 1 ”, “AD 2 ”, . . . represent the first, second, . . . analog inputs AD  301 . “SL 1 - 1 ”, . . . represent the first, second, . . . option card inputs  302  of the first slot. “SL 1 - 2 ”, . . . represent the first, second, . . . option card inputs  302  of the second slot. “RTN 1 ” and “RTN 2 ” represent the inputs to the effect return channels  313 . “EFF 1  L/R” and “EFF 2  L/R” assigned to “RTN 1 ” and “RTN 2 ” indicate that the effect inputs EF  306  are assigned to the effect return channels  313 . 
   An EFFECT PATCH area  402  is used for designating which inputs are assigned to the internal effectors. “EFF 1 ” and “EFF 2 ” represent internal effectors. In this case, inputs from AUX 7  and AUX 8  are input to the internal effectors. 
   An HDR TRACK INPUT ASSIGN area  403  is used for the assignment by the record selector  318 . Numerals “ 1 ” to “ 16 ” represent sixteen tracks, and the assigned inputs are shown under the numerals as “BUS 1 ”, “BUS 2 ”, . . . , “DIR 1 ”, “DIR 2 ”, . . . . “BUS 1 ”, “BUS 2 ”, . . . represent inputs from the general buses BUS 1  to BUS 8 . “DIR 1 ”, “DIR 1 ”, . . . represent inputs from the direct-outs of the mixer input channels  312 . 
   By using the window shown in  FIG. 4 , inputs to each mixer input channel  312 , each internal effector, and each track of the HD recorder  319  can be set. For example, when an input to each input channel is to be set, the cursor is moved to the display area of a desired input channel by using the cursor motion keys  221 , and then the value input operator unit (data input dial)  222  is manipulated to sequentially display available inputs to the input channel and select a desired input. It is apparent that an external input from the slot can be selected as an input source only when an input card is inserted into the slot. 
     FIG. 5  shows a window to be used for designating whether each input channel (mixer input channel) is output to which one of the general buses BUS 1  to BUS 8 . A Pan  1 - 16  button  501  is used for the input channel # 1  to # 16 , and a Pan  17 - 24  button  502  is used for the input channel # 17  to # 24 . Display contents  511  for the input channel # 1  indicate that outputs are assigned to the general buses BUS 1  to BUS 8  or the stereo record buses Stereo_L/R. Numerals “ 1 ” to “ 8 ” surrounded by squares represent the general buses BUS 1  to BUS 8 , and “ST” surrounded by a square represents the stereo record buses Stereo_L/R. If the numeral or characters ST are displayed in reversed color, it means that the corresponding output is assigned. A setting display  512  indicates a pan (right and left orientation) of the input channel # 1 . 
   In this apparatus, inputs (mixer input channels) from other apparatuses and inputs (recorder channels) reproduced by the recorder are distinguished. The mixer input channels are distinguished from the recorder channels as in the following. 
   Inputs to the mixer input channels can be changed by patching. Inputs to the recorder channels are fixed to the predetermined tracks of the recorder. Since this correspondence is fixed, a user can easily understand the connection state. 
   The mixer input channels # 1  to # 16 ) have connections (direct-outs) for directly inputting signals to the channel # 1  to # 16  of the recorder without involvement of the mixing buses. The recorder channels have no direct connections to the recorder. 
     FIG. 6  shows a quick record setting window to be displayed when the QUICK REC key  267  is turned on. This window is displayed by reading data from a predetermined buffer. When the power of the apparatus is first tuned on, the window shown in  FIG. 6  is displayed which reflects the setting state entered in the patch window shown in  FIG. 4 . In this case, connections in the window are cleared. As will be later described, after various connections are edited on the window shown in  FIG. 6 , this edition is reflected upon the buffer irrespective of whether the edition is executed in response to turning on an EXECUTE button or whether the edition is canceled by an EXIT key. Therefore, when the QUICK REC key  267  is turned on, the quick record setting window reflecting the state immediately before the key is turned on is reflected. Connections can be edited visually on this window so that a patch operation between input sources and record tracks can be made easily. If the REC key  254  and PLAY key  253  are depressed at the same time, the real record state can be navigated. 
   Referring to  FIG. 6 , in a display area  601 , a channel number of each channel and input sources (AD 1 , SL 1 - 1 , and etc.) are displayed. A change in settings of the mixer input channels cannot be made on this window. CH 1  to CH 16  displayed in a display area  611  correspond the channels # 1  to # 16  of the mixer input channels  312  and this display is fixed. CH 1  to CH 16  are the numbers of the mixer input channels. In a display area  612  on the right side of the channel number display area  611 , input sources to the channels are displayed. An input source can be changed by the operation to be described later. In a display area  605 , track numbers TR 1  to TR 16  are displayed and this display is fixed. TR 1  to TR 16  are the numbers of the record tracks. Terminals  602  and terminals  604  are used as connection terminals, and prepared for the mixer input channels CH 1  to CH 16  and track input channels TR 1  to TR 16 . A display  603  of a plug and a cord is used for connecting the terminals and display a patch state. The display  603  of the plug and cord between the terminals  602  and  604  can be set as desired to change the patch state. 
   There are a CURRENT bottom  608 , a FLAT button  609 , CLEAR buttons  606 , an ALL CLEAR button  607  and an EXECUTE button  610 . The cursor is moved to a desired button by using the cursor motion keys  211  and the enter key is depressed to turn on the button. 
   With reference to  FIGS. 10 and 11 , how the cursor is moved on the window shown in  FIG. 6  will be described. The cursor can be moved up/down and right/left by using the cursor motion keys  221 . The positions of the cursor where the assignment can be set are fixed. The assignment can be set with the cursor only in areas  1001  to  1005  shown in  FIG. 10 . In the area  1001 , the input sources allocated to the mixer input channels are displayed. The cursor can be moved to each input source. In the area  1002 , the terminal for each mixer input channel is displayed. The cursor can be moved to each terminal. In the area  1003 , terminals corresponding to record tracks are displayed. In the area  1004 , a clear button group is displayed. The cursor can be moved to each clear button. In the area  1005 , the CURRENT button  608 , FLAT button  609  and EXECUTE button  610  are displayed. The cursor can be moved to each button. As the cursor is moved right and left, it moves throughout these areas  1001  to  1005 . 
     FIG. 11  shows the area in which the cursor moves up and down. At the uppermost row, the cursor is in an area  1101 . As the cursor is moved down from the uppermost row, the cursor enters an area  1102  and then enters an area  1103  at the lowermost row. 
   The area where the cursor can move is fixed. In this area, as a user manipulates the up/down and right/left direction cursor motion keys, the cursor moves up/down and right/left corresponding in visual amount to the operation degree of the keys. The operation of the quick record setting on the window shown in  FIG. 6  will be described. 
   After the cursor is moved to one of the mixer input channels CH 1  to CH 16  in the area  612 , the data input dial  222  is rotated to sequentially display selection candidates “AD 1 ” to “AD 8 ”, “SL 1 - 1 ” to “SL 1 - 8 ”, “SL 2 - 1 ” to “SL 2 - 8 ”, “Din L”, “Din R”, “MET”, and “SMP 1 ” to “SMP 8 ”. By selecting a desired input source, the input source of the channel can be changed. “AD 1 ” to “AD 8 ” correspond to the analog inputs  301 , “SL 1 - 1 ” to “SL 1 - 8 ” and “SL 2 - 1 ” to “SL 2 - 8 ” correspond to the inputs from the cards inserted into the slots  302  and  303 . “Din L” and “Din R” correspond to the digital inputs  304 . “MET” corresponds to the input from a metronome, and “SMP 1 ” to “SMP 8 ” correspond to the inputs from the internal sampler  5 . The state indicated at  901  in  FIG. 9  corresponds to the state that the input source is set to SL 1 - 1  by moving the cursor to the channel CH 9  and operating the data input dial  222  to select SL 1 - 1 . This state is loaded in the buffer. 
   The mixer input channels CH 1  to CH 16  and record tracks TR 1  to TR 16  may be connected in one-to-one correspondence or in one-to-multiple correspondence. A multiple-to-one correspondence is not possible. Settings other than those described above are made by using a more detailed patch window. 
   Wirings between the mixer input channels CH 1  to CH 16  and record tracks TR 1  to TR 16 , i.e., connections between the terminals  602  and terminals  604 , are established in the following manner. In the following, selecting first one of the mixer input terminals CH 1  to CH 16  and selecting first one of the record tracks TR 1  to TR 16  will be described separately. 
   If one of the mixer input channels CH 1  to CH 16  is to be first selected, the cursor is moved to one of the mixer input channels CH 1  to CH 16  and the enter key  223  is depressed to select the desired mixer input channel. When the enter key  223  is depressed, the number of the selected mixer input channel and the input source are displayed in reversed color. This reversed color display of the number of the mixer input channel and the input source is maintained unchanged during the following wiring work. After the mixer input channel is selected, the cursor is inhibited to move in the area other than the mixer input channel display area  1002  in  FIG. 10  and the record track display area  1003  in  FIG. 10 , until the wiring work is completed. 
   After the mixer input channel is selected and if the cursor is moved to a different mixer input terminal and the enter key  223  is depressed, the selection state of the first selected channel is released and the newly designated channel is selected. After the mixer input channel is selected and if the cursor is moved to the same mixer input channel and the enter key  223  is depressed, the selection state of the channel is released and the wiring work is terminated. 
   After the mixer input channel is selected and if the cursor is moved to one of the terminals  604  of the record tracks, one of the record track numbers TR 1  to TR 16  at which the cursor is set is displayed in reversed color. In this state, if the cursor is moved up and down in the area  1003  shown in  FIG. 10 , the number to be displayed in reversed color is changed. Irrespective of how record settings are entered, the cursor can be moved to any one of the track terminals. When the enter key  223  is depressed after the cursor is moved to the desired track terminal, the track can be selected and the wiring work is completed. After this wiring work, the reversed color display is changed to the initial display. The plug and cord are drawn on the window. After the wiring work, the limited motion of the cursor is released. 
   The window shown in  FIG. 6  displays the cursor  621  set to the terminal of CH 5 . The window shown in  FIG. 7  shows the cursor moved to the terminal of TR 9  after the channel CH 5  is selected and an area  701  is displayed in reversed color. An area  702  of the channel TR 9  is displayed in reversed color, and the cursor is set to the terminal  703  of the channel TR 9 . In this state, when the enter key  223  is depressed, a connection  801  shown in  FIG. 8  is completed. 
   If the cursor is set to the terminal of the track already set as the record destination and the enter key  223  is depressed, the already set connection is made invalid, and the newly set connection is made valid to thereafter terminate the wiring work. 
   If one of the record tracks TR 1  to TR 11  is to be first selected, the cursor is moved to the terminal of one of the track channels TR 1  to TR 16  and the enter key  223  is depressed to select the desired record track of the recorder. When the enter key  223  is depressed, the number of the selected track is displayed in reversed color. This reversed color display of the number of the track is maintained unchanged during the following wiring work. After the track is selected, the cursor is inhibited to move in the area other than the mixer input channel display area  1002  in  FIG. 10  and the record track display area  1003  in  FIG. 10 , until the wiring work is completed. 
   After the track is selected and if the cursor is moved to a different track and the enter key  223  is depressed, the selection state of the first selected track is released and the newly designated track is selected. After the track is selected and if the cursor is moved to the same track and the enter key  223  is depressed, the selection state of the track is released and the wiring work is terminated. 
   After the track is selected and if the cursor is moved to one of the mixer input terminals  602 , the number of the mixer input channel corresponding to the terminal and the input source are displayed in reversed color. in this state, if the cursor is moved up and down in the area  1002  shown in  FIG. 10 , the number and input source to be displayed in reversed color are changed. The cursor can be moved to any one of the mixer input channels. When the enter key  223  is depressed after the cursor is moved to the desired mixer input channel, the mixer input channel can be selected and the wiring work is completed. After this wiring work, the reverse display is changed to the initial display. The plug and cord are drawn on the window. After the wiring work, the limited motion of the cursor is released. 
   The CLEAR button  607  is provided for each of the tracks and is used for releasing the connection of the track. When the ALL CLEAR bottom is turned on, the connections of all tracks can be released. 
   Irrespective of whether the EXECUTE button  607  is depressed, the connections displayed on the window are loaded in the buffer each time one wiring line is connected or released on the window. 
   Either one of the CURRENT button  608  and FLAT button  609  is always on, and these buttons operate in a toggle manner. Namely, when the FLAT button  609  is turned on while the CURRENT button  608  is on, the CURRENT button  608  is forcibly turned off. The opposite case is also true. When the EXECUTE button  607  is turned on, the patch state displayed on the window (assignment of input signals to the mixer input channels and connections of the mixer input channels to the record tracks) is executed. In this case, the setting state of the mixer input channels selected as record sources is either set to the initial state or maintained as it is, depending on whether the CURRENT button  608  is on or the FLAT button  609  is on. If the setting state of the mixer input channels is initialized after the quick record setting as in a conventional case, the same setting is required to enter again. in this embodiment, if the CURRENT button  608  is maintained on, the setting state of the mixer input channels selected as the record sources is maintained so that it is easy for the user to use this apparatus. If the setting state of the mixer input channels is desired to be initialized, the FLAT button  609  is depressed. 
   After the connection is set or released in the above manner, the EXECUTE button  610  is depressed to perform the following processes. 
     FIG. 12A  is a flow chart illustrating the processes to be executed when the EXECUTE button  607  is turned on while the FLAT button  609  is turned on. At Step  1201 , the assignment (input patch) of input signals to the mixer input channels is changed to the assignment displayed on the window. At Step  1202 , a channel library # 01  is called only for the mixer input channels selected as the record sources. The channel library is a file storing various setting conditions such as the setting conditions of a compressor, an equalizer and the like, the setting conditions of the levels and the like of the faders, and the routing setting conditions indicating the output destination of each mixer input channel. As the channel library, a plurality of preset files are prepared in HD  108 . The channel library # 01  is a file storing the standard setting conditions. At Step  1202 , therefore, the standard setting conditions are set to the mixer input channels selected as the record sources. With the standard setting conditions, the compressor, equalizer and the like are set flat (not in operation), the fader is set to a standard level of 0 dB (the volume is not necessarily 0), and the routing is on only for the stereo buses. Next, at Step  1203 , the routing to the stereo buses is set off only for the mixer input channels selected as the record sources. This setting is made because the stereo buses  315  are used for the record monitor buses. 
   If paired mixer input channels are selected as the record sources, this paring is released and the channel library # 01  is called only for the mixer input channels selected as the record sources. 
   Next, at Step  1204 , the connection patch between the mixer input channels and record tracks wired on the window is changed. In an recorder track input assign area (an HDR TRACK INPUT ASSIGN area  403  in  FIG. 4 ), the direct-outs for the mixer input channels selected as the record sources are assigned. At Step  1205  a REC READY of each track selected as the record destination is turned on. The track with the turned-on REC READY is used as the record track. In this embodiment, since the direct-outs are used by the quick record setting, it is possible to maintain unchanged the settings of other mixer input channels, recorder channels, mixing buses and the like which were not subjected to the quick record setting. 
   At Step  1206  the channel library # 01  is called for the monitor channels (recorder channels  320 ) of the tracks selected as the record destinations. The outputs of the recorder channels are therefore routed to and mixed at the stereo buses  315 . A user can monitor the record by connecting outputs of the stereo buses to a monitor sound system by using the output patch. In this case, if paired channels are selected as the record destinations, this paring is released and the channel library # 01  is called for the channels selected as the record destinations. Lastly, at Step  1207  a fader layer for the channels # 1  to # 16  are set to the selection state and the page of the window is changed to a predetermined page to terminate the processes. 
     FIG. 12B  is a flow chart illustrating the processes to be executed when the EXECUTE button  607  is turned on while the CURRENT button  608  is turned on. Step  1211  corresponds to Step  1201  shown in  FIG. 12A , and Steps  1213  to  1217  correspond to Steps  1203  to  1207  shown in  FIG. 12A . While the CURRENT button  608  is on, Step  1202  shown in  FIG. 12A  is not executed. Since Step  1202  is not executed while the CURRENT button  608  is on, the setting conditions of the mixer input channels selected as the record sources are not initialized but maintained unchanged. When routing of the assignment of the mixer input channels selected as the record sources to the stereo buses is turned off at Step  1213  (without changing the other settings), the assignment of both paired channels to the stereo buses is turned off if one of the paired channels is used as the record source, and the other is not used as the record source. 
   In both the processes illustrated in  FIGS. 12A and 12B , the setting conditions of mixer input channels not designated as the record sources are maintained unchanged (the selection as the record sources is not designated). For the routing to the monitor stereo buses  315 , the recorder channels selected as the record destinations are routed to the stereo buses, whereas the setting conditions of the routing of recorder channels not selected as the record destinations are inherited as they are. With this settings, it is possible to monitor the record and maintain unchanged the setting conditions of tracks not designated as the record sources. Routing of the tracks not designated as the record destinations to the stereo buses  315  may be inhibited. By inhibiting the routing, only the record tracks can be monitored. Routing of the recorder channels not selected as the record destinations may be inherited in one mode or this routing to the stereo buses  315  may be inhibited in another mode. 
   Since the quick record setting is executed by depressing the EXECUTE button  610 , or in other words, since the quick record setting (an input patch of input channels, various settings of input channels, track settings and the like) is not executed before the EXECUTE button  610  is depressed, the quick record setting windows described with reference to  FIGS. 6 to 9  can be exited by depressing an unrepresented EXIT key. 
   Although the patch (input patch) is reflected on the contents in the HDR TRACK INPUT ASSIGN area  403  shown in  FIG. 4 , the patch set in the HDR TRACK INPUT ASSIGN area  403  is not reflected on the contents of the quick record setting window. When the quick record setting window is accessed from another window, the connections stored in the buffer are displayed. As a default (immediately after the power is turned on), the contents of the current scene only for the input patch are reflected without any connection, and a library for quick record setting is not prepared. 
   The present invention has been described in connection with the preferred embodiments. The invention is not limited only to the above embodiments. It is apparent that various modifications, improvements, combinations, and the like can be made by those skilled in the art.
