Yamaha Yamaha Mixing Consol, M2500 owner manual Midi data format

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..

70	MONO/C OUT
105–112	DIRECT RECALL(1–8)
	= MUTE GROUP(1–8)

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.
