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. 4.

Refer below for details. Velocity of 0 x00 is equivalent to Note-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) 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. If Control Change Tx is On, control change messages will be transmitted on the MIDI Tx Ch channel when you operate a parameter. The control value is converted into a parameter value according to the following equation.

PROGRAM CHANGE (Cn) If Program Change Rx is On, program change messages will be received when MIDI Rx Ch matches. However, if MIDI Rx Ch is OMNI, this message is received regardless of the channel. A scene memory will be recalled according to the PROGRAM CHANGE TABLE settings. If Program Change Tx is On, a program change will be transmitted on the MIDI Tx Ch according to the PROGRAM CHANGE TABLE settings when you recall a memory. If the recalled memory number has been assigned to more than one program number, the lowest- numbered program number will be transmitted. 5.5. MIDI TIME CODE QUARTER FRAME (F1) If SYNC OUT is set to MTC, Quarter Frame messages will be transmitted according to the time code movements of the recorder when the recorder is playing or recording. This message is received if MTC SYNC MODE is set to SLAVE. Quarter Frame messages received in realtime are internally assem- bled into time code that controls the recorder. 5.6. SONG POSITION POINTER (F2) If SYNC OUT is MIDI CLOCK, a song position message will be transmitted when STOP or LOCATE is performed on the recorder, to indicate the song position from which the song should start at the next START or CONTINUE message. 5.7. TIMING CLOCK (F8) If SYNC OUT is MIDI CLOCK, this message is transmitted according to the MIDI Tempo Map from when the recorder begins playing or recording, until it stops. 5.8. START (FA) If SYNC OUT is MIDI CLOCK, this message is transmitted when the recorder begins playing or recording at a location other than the first measure. 5.9. CONTINUE (FB) If SYNC OUT is MIDI CLOCK, this message is transmitted when the recorder begins playing or recording at a location other than the first measure. STATUS1100nnnn Cn Program Change DATA0nnnnnnn nnProgram No. ( 0-127) 5.10. STOP (FC) If SYNC OUT is MIDI CLOCK, this message is transmitted when the recorder stops. 5.11. ACTIVE SENSING (FE) Once this message is received, subsequent failure to receive any mes-sage for a period of 300 ms will cause Running Status to be cleared, and MIDI communications to be initialized. 5.12. RESET (FF) When a Reset message is received, MIDI communications will be initialized by clearing Running Status etc. 5.13. EXCLUSIVE MESSAGE (F0-F7) 5.13.1. MMC 5.13.1.1. MMC STOP When the STOP key is pressed, this message is transmitted with a device number of 7F. If the AW2400 is operating as an MMC Slave, the transport will stop when this message is received with a matching device number or a device number of 7F. 5.13.1.2. MMC PLAY If the AW2400 is operating as an MMC Slave, the transport will begin playback when this message is received with a matching device number or a device number of 7F. 5.13.1.3. MMC DEFERRED PLAY This message is transmitted with a device number of 7F when the PLAY key is pressed. If the AW2400 is operating as an MMC Slave, the transport will begin playback when this message is received with a matching device number or a device number of 7F.
