an external MIDI device and the DR-670, the
MIDI channel settings must be the same for both
devices. Performance data can be exchanged
successfully only when the MIDI channels match.

Note Number for that key pad is transmitted.
When a Note Number is received from an
external MIDI device, the instrument or bass
tone assigned to the key pad corresponding to
that Note Number is played.

* Note Numbers that do not correspond to any of

the key pads are disregarded if received.

handled by the devices you are connecting, refer
to the owner’s manual for each device.
