Yamaha AW2400 Remote Port, MTC Sync Mode, MTC Sync Average, MTC Sync Offset, Channel Message

MIDI data format

3.1.7. OTHER

If this is set to ECHO, the received MIDI data will be echoed at the transmission port. However, Program Change and Control Change will follow their own settings.

3.1.8. REMOTE PORT

Specify the output port when the MIDI remote function is engaged.

3.1.9. THRU

Set the MIDI through function.

3.1.10. MMC MODE

Select whether the AW2400 will be the MMC MASTER or SLAVE.

3.1.11. MMC Dev.

Specify the ID number that will be used when transmitting or receiv- ing MMC commands.

3.1.12. MTC SYNC MODE

Select whether the AW2400 will be the MTC MASTER or SLAVE.

3.1.13. MTC SYNC AVERAGE

When the AW2400 is functioning as a MTC SLAVE, this setting specifies how it will follow the MTC data. Set this to 0 if the incom- ing MTC data has a highly accurate timing; set this to 1 or 2 if the timing of the incoming MTC data is not as accurate (such as when receiving MTC from a software sequencer).

3.1.14. MTC SYNC OFFSET

When the AW2400 is functioning as a MTC SLAVE, this setting adds an offset to the received MTC data. The received time code value shifted by this amount will correspond to the location indicated by the internal time code of the AW2400.

3.1.15. SYNC OUT

Turn on/off the output of MTC/MIDI CLOCK.

5. MIDI format details

5.1. NOTE OFF (8n)

< Reception >

Received when [Rx CH] matches.

Used to control Effects/Pitch Fix. Refer NOTE ON for details.

STATUS	1000nnnn	8n	Note Off Message
DATA	0nnnnnnn	nn	Note No.
	0vvvvvvv	vv	Velocity (ignored)

5.2. NOTE ON (9n)

< Reception >

Received when [Rx CH] matches.

Used to control Effects/Pitch Fix. Refer below for details. Velocity of 0x00 is equivalent to Note-Off.

STATUS	1001nnnn	9n	Note On Message
DATA	0nnnnnnn	nn	Note No.
	0vvvvvvv	vv	Velocity (1-127:On, 0:Off)

* Effect control by Note

1: Dynamic Flange/Dynamic Phase/Dynamic Filter

When the SOURCE parameter is set to MIDI, the note velocity (both note-on and note-off) is used to control the Modulation frequency width.

5.3. CONTROL CHANGE (Bn)

< Reception >

If [Control Change Rx] is On, control change messages will be recevied when [MIDI Rx Ch] matches. However, if [MIDI Rx Ch] is OMNI or [Control Change Mode] is 1, reception will occur regard- less of MIDI channel.

< Transmission >

If [Control Change Tx] is On, control change messages will be trans- mitted on the [MIDI Tx Ch] channel when you operate a parameter.

STATUS	1011nnnn	Bn	Control Change
DATA	0ccccccc	cc	Control No. (0-95, 102-119)
	0vvvvvvv	vv	Control Value (0-127)

The control value is converted into a parameter value according to the following equation.

S= total number of steps in the parameter’s variable range 128 / S = X remainder Y

INT((Y+1)/2) = Z

If (MIDI DATA - Z) < 0, then Value = 0

If ((MIDI DATA - Z)/X) > MAX, then Value = MAX Otherwise, Value = INT ((MIDI DATA -Z)/X)
