Abstract:
1. A signal reproducing device comprising: a signal storing device for storing a plurality of sequential signals, respective sequential signals representing a single tune, and the respective sequential signals representing a single tune including a head portion and a remaining portion other than the head portion; a buffer memory for storing sequential signals read out from the signal storing device; a signal processing circuit for reading out a sequential signal stored in the signal storing device for temporary storage in the buffer memory, and thereafter reading out and reproducing the sequential signal from the buffer memory, the buffer memory being concurrently provided with a first storing area for storing respective head portions of a plurality of the sequential signals and a second storing area for storing a remaining portion other than the head portion of at least one sequential signal representing a single tune, wherein the first storing area stores a number of the respective head portions of the sequential signals that is greater than a number of remaining portions other than the head portion of the at least one sequential signal stored in the second storing area, wherein when a signal selecting manipulation is made with the respective head portions of the plurality of sequential signals stored in the first storing area of the buffer memory, the signal processing circuit reads out and reproduces a head portion of a selected sequential signal from the first storing area; and during reading out and reproducing the head portion of the selected sequential signal from the first storing area of the buffer memory, the signal processing circuit reads out a remaining portion other than the head portion of the selected sequential signal from the signal storing device for storage in the second storing area of the buffer memory, and while the head portion of the selected sequential signal is being read out and reproduced from the first storing area of the buffer memory, only the remaining portion of the selected sequential signal is stored in the second storing area of the buffer memory; and after completion of the operation of reading out and reproducing the head portion of the selected sequential signal from the first storing area, the signal processing circuit reads out and reproduces the remaining portion of the selected sequential signal from the second storing area of the buffer memory.
