■MIDI Bulk In

With a MIDI cable, connect the DG100-212’s MIDI IN jack to the MIDI OUT jack
on an external MIDI device. Return your MIDI back up data to the DG100-212.
* The MIDI Bulk In operation is carried out in the AMP or TAPE ECHO modes
only. It can not be carried out in the Utility Mode.
* The device number is the same as that of the MIDI receive channel. If the MIDI
receive channel is set to “All” (Omni On), the MIDI channel will be set to 1.
The DG100-212 will not receive data if the MIDI channel is set to “oF” (OFF).
* “Ld” is shown on the display while the MIDI Bulk In operation is being ex-
ecuted.

■Speaker Simulator ON/OFF
