Yamaha DX27 Electronic Keyboard User Manual


 
3: CHANNEL
The DX27 is capable of receiving or transmitting data on any of the 16 available
MIDI channels, or receiving in the OMNI mode which enables reception on all
channels simultaneously. This function is used to set the desired MIDI receive or
transmit channel or activate the OMNI receive mode. The receive or transmit channel
is normally set to match the transmission or reception channel of the MIDI equipment
to which the DX27 is connected.
Data is entered using the DATA ENTRY control or -1/+1 buttons. Subsequent
presses on the CHANNEL button call the “Omni: on/off,” “Midi R Ch=1—16,” and
“Midi T Ch=1—16” selection modes.
