Abstract
The present invention is an apparatus and method for ecoding data in MIDI (Musical Instrument Digital Interface) format on an audio compact disc without affecting the digitized sound stored in the main channel by utilizing what is known as the subcode channel of the compact disc which is reserved for information other than digitized compact disc audio data. The invention is directed to a technique for converting MIDI information generated by a MIDI source (for example, a keyboard or sequencer) into subcode data which may be recorded on a transportable floppy diskettes or other transportable media for subsequent conversion to signals which are input to a compact disc encoder which places the MIDI information into the subcode channel.
