Yamaha PSR-550 Owner's Manual - Page 108

The PSR-550 is an electronic musical instrument which is capable of transmitting and receiving over sixteen channels. Imagine that there are sixteen separate pipes in the connected MIDI cable. When transmitting MIDI data from the PSR-550 to an external device, MIDI data is sent through the assigned pipe (or MIDI channel) and transmitted to the external device. For example, several tracks can be transmitted simultaneously, including the auto accompaniment data (as shown below). When recording performance data using the Auto Accompaniment on an external sequencer PSR-550 part Voice R1 Voice L Auto Accompaniment Bass Auto Accompaniment Chord 1 Auto Accompaniment Chord 2 Auto Accompaniment Pad Auto Accompaniment Phrase 1 Auto Accompaniment Phrase 2 Auto Accompaniment Rhythm Main Auto Accompaniment Rhythm Sub Voice R2 MIDI cable Channel 1 Channel 2 Channel 3 Channel 4 Channel 5 Channel 6 Channel 7 Channel 8 Channel 9 Channel 10 Channel 11 External sequencer Track 1 Track 2 Track 3 Track 4 Track 5 Track 6 Track 7 Track 8 Track 9 Track 10 Track 11 As you can see, it is essential to determine which data is to be sent over which MIDI channel when transmitting MIDI data (page 114). What You Can Do With MIDI q Use the PSR-550 as a multi tone generator (playing 16 channels at one time). PSR-550 Receive mode for all channels set to "XG/GM."
