REFERENCE TO RELATED APPLICATION 
     This invention is the subject of provisional application Ser. No. 60/087,348 entitled REAL TIME TRANSMISSION OF KEYBOARD MUSICAL PERFORMANCE filed May 29, 1998. 
    
    
     The present invention is concerned with the real time transmission of keyboard music performances performed by a musician at one venue or location to one or more remote venues. For example, a performance by a noted pianist can be recreated at a plurality of remote sites or venues in real time and presented to the audience at the different venues as if they were at the actual performance. 
     The accurate and precise sensing of a musical keyboard actuation and MIDI thereof is disclosed in my U.S. Pat. Nos. 5,440,072, 5,459,282 and in my pending application Ser. No. 08/679,926 which issued as U.S. Pat. No. 5,763,806 on Jun. 9, 1998. In those prior patents and pending application, I disclose a system for effectively transforming the musician&#39;s fingers and finger actuation of keyboards into electrical signals in a cost-effective and expeditious way. 
     In accordance with the present invention, midified signals from a keyboard equipped with key actuation sensors (which sense key actuation and key actuation expression effects) is coupled to a modem which, in turn, couples the signals via transmission medium (telephone, including wires, fiber, satellites, etc.) to a remote venue or site where the MIDI signals are coupled to a sequencer used to reproduce the identical piano performance by the musician at remote sites, respectively, in real time with the original piano performance by the pianist or musician. Thus, the basic objective of the invention is to cause the performance of a keyboard musician at one location or venue to be reproduced in real time at one or more remote sites or venues. At the same time, video cameras may be trained on the musician to convey live images to the sites of the remote venues for visual presentation. This, it will be recognized, is in direct contrast to video performances which are video transmitted because, in those performances, the actual sound is converted to a soundtrack with the video and transmitted. In the present case, only the images are transmitted and the actual reproduction or musical sound is produced live at the remote site or venue as if they were at the site where the performance was actually created by the musician. 
    
    
     DESCRIPTION OF THE DRAWINGS 
     The above and other objects, advantages and features of the invention will become more apparent when considered with the following specification and attached drawing wherein: 
     FIG. 1 is a functional block diagram of a system for the real time transmission of a keyboard musical performance simultaneously to a plurality of venues for recreation of the musical performance of these venues. 
    
    
     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawing, a musician M is shown seated at a keyboard KB having key actuation sensor strips  10  (which may be of the type disclosed in my above referenced patents) for sensing key actuation and expression affects provided by the musician to a MIDI controller  11 . Also, pedal sensors  13  are coupled to the MIDI controller  11  to provide the MIDI controller  11  with the pedal actuation signals. MIDI signals are provided by the MIDI controller to one or more modems M 1 , M 2 , M 3  . . . MN. A video camera VC provides video signals of the visual performance to modems M 1 , M 2  . . . MN so that there is provided to the modems for relay to distant venue points a compilation of electrical signals comprised of video pictures or images of the musician providing the performance and output from MIDI controllers to the modem. Thus, instead of a microphone picking up the sounds and, thereby inevitably providing some distortion, the digital equivalent of the musician&#39;s actual performance in the form of digital signals from the MIDI controller are provided to the modems for transmission to the performance venue just as if the musician was physically present at the remote revenue. In the first channel, the modems supplies the combined MIDI controller signals and the video images to a transmitter  20  which broadcasts either directly or via satellite  21  for relaying to receivers  22 - 1 ,  22 - 2  . . .  22 -N. Each receiver has a video channel  9  which receives and converts video images to a visual representation on display screen DS of the musician providing the performance. In parallel and synchronism therewith, the sound module  25  converts the received MIDI controller signals from the MIDI controller  11  to electrical signals corresponding to the musician&#39;s actuation of each key in synchronism with the visual images provided on the screen which are amplified in power amplifier  26  and applied to speaker  27  so that the audience in venues No.  1  . . . N will hear the actual performance with the sounds created via the modification of signals by the key actuation sensor strips and MIDI controller. 
     In the second receiver channel  22 -N, an identical video  23 -N, and display screen  24 -N are provided in a venue N which has a corresponding sound module  25 -N, power amplifier  26 -N and speaker  27 -N, so that in several different venues, although images are reproduced from a video camera, the sound presented to the audience at that given venue will hear sounds created exactly as provided by the live musician. 
     In the second medium, the signals from the modem are conveyed via telephone company signals  30  via a modem receiver  31  and sound module  32  which drives a power amplifier  33  and speaker  34 . A video receiver  23 TV converts the video images for display on a display screen  24 . In like manner, the modem M-N provides signals to a fiber optic channel  40  which couples them to a modem receiver  41  which has a sound module  42  and a video receiver  43 . Video receiver  43  drives the display screen at fiber optic venue F 1  and the sound module  32 F drives the power amplifier  26 F which in turn drives a speaker  27 F. Thus, a plurality of different venues may be serviced from a single performance by way of radio transmission, telephone lines or by fiber optic communications, and at all of the performances, substantially simultaneous rendition of the live performance will be rendered with the sound or audio portion of the program material being generated live from MIDI signals at a host or plurality of different venues. 
     While the preferred embodiment of the invention has been shown, illustrated and described, it will be appreciated that other embodiments, adaptations and variations of the invention will be readily apparent to those skilled in the art.
