MIDI data format
1. MIDI Channel
The same channel is used for transmission and recep-
tion. Select from channel numbers 1–16.
2. MIDI Program Change
Program change numbers (0–127) correspond to
scene memory numbers 1–128. This correspondence
cannot be changed. However, when Mute Groups are
used, program change numbers 0–7 cannot be trans-
mitted or received. (Since memory numbers 1–8
≠
program change numbers 0–7.)
In the case of Omni [on], program changes of all
MIDI channels are received.
Transmission and reception are switchable [LoC/on/
oFF]. When [LoC/on] are selected, program changes
can be received/transmitted. When [LoC] is selected,
program change messages can be transmitted to con-
trol an external MIDI device even when a <no data>
recall operation occurs.
3. MIDI Control Change
Control changes correspond to the ON/EDIT switch
and the DIRECT RECALL switches. This correspon-
dence cannot be changed. However, control change
numbers 105–112 correspond to DIRECT RECALL
1–8 switches only when Mute Groups are being used.
Transmission and reception are switchable [on/GrP/
oFF]. When [GrP] is selected, only those control
change messages that correspond to mute groups are
transmitted or received..
4. MIDI Echo Back
The Echo Back function is switchable [on/oFF].
However if the internal transmission buffer becomes
full while echoing back a long exclusive messages,
echo back will be halted, and the internal data will be
transmitted.
5. Bulk Out, Bulk Dump Request
The following bulk data can be transmitted and
received.
