Midi Channels - Yamaha Motif DDK-7 Owner's Manual

MIDI Channels

MIDI data is assigned to one of sixteen MIDI channels. Using these channels, 1 – 16,
the performance data for sixteen different instrument parts can be simultaneously sent
over one MIDI cable.
Think of the MIDI channels as TV channels. Each TV station transmits its broadcasts
over a specific channel. Your home TV set receives many different programs
simultaneously from several TV stations and you select the appropriate channel to
watch the desired program.

MIDI operates on the same basic principle. The transmitting instrument sends MIDI
data on a specific MIDI channel (MIDI Transmit Channel) via a single MIDI cable to
the receiving instrument. If the receiving instrument's MIDI channel (MIDI Receive
Channel) matches the Transmit Channel, the receiving instrument will sound
according to the data sent by the transmitting instrument.

The receive channel of the DDK-7 is fixed at channel 1 for the Upper Keyboard,
channel 2 for the Lower Keyboard, and channel 3 for the Pedalboard. This means that
when you are using another MIDI device to play the DDK-7's Voices, you must set the
MIDI transmit channel(s) of the connected device to match the receive channel(s) of
the DDK-7. You can select the transmit channel for each keyboard (Upper, Lower and
Pedal) from channels 1 – 16. See page 238 for more information.
