Ш MIDI MESSAGES
[ MIDI CHANNELS
MIDI uses 16 different channels to transfer digital
messages from device to device. The transmitting device
sends the messages for all 16 channels simultaneously.
The receiving device is set to receive MIDI data for a
single specified channel. It may be helpful to compare
this to television broadcasting. From all the television
channels broadcast, the channel that is received (and the
program that is watched) depends on the channel se-
lected. MIDI channels operate similarly; there are 16
channels and each channel contains a different message.
Each channel is transmitted independently and the MIDI
receiving instrument (slave) receives messages for a
particular channel.
NOTE: The transmit channel number of the master must match
the receive channel of the slave before messages can be
communicated.
