Synchronizing to the VS-880 (Master)

When you want to synchronize the MIDI sequencer to the VS-880, use the following procedure.

1.Use a MIDI cable to connect the VS-880 and the MIDI sequencer as follows.

	MIDI	DIGITAL (5,6)	FOOT PHONES
OUT THRU	IN	IN	SWITCH
		OUT
		MIDI IN	MIDI sequencer
			(implements MTC)

2.Make sure that the MIDI OUT/THRU connector is set for use as a MIDI OUT connector. With the factory set- tings, MIDI OUT is selected.

Press [SYSTEM], select “SYS MIDI PRM?”, select “SYS MID: MIDIThr=”, and make sure that it is set to “Out.”

3.Make settings so that MTC will be used for synchro- nization.

Press [SYSTEM], select “SYS Sync/Tempo ?”, and set the following parameters.

Gen.: Set this to ÒMTC.Ó

MTC Type: Select the desired type of MTC.

4.This completes synchronization settings for the VS-880. Press [PLAY (DISPLAY)] to return to Play condition.

5.Make settings on your MIDI sequencer so that it will synchronize to incoming MTC, and prepare it to begin playback of MIDI song data. When you start playback on the VS-880, the MIDI sequencer will begin playback in synchronization.

Gen (Sync generator)

This selects the type of synchronization signal that will be transmitted from the MIDI OUT connector. When using a synchronization signal from the VS-880 to synchronize external MIDI devices, set this to the desired type of syn- chronization signal.

Off: Synchronization signals will not be transmit- ted.

MTC: MIDI Time Code will be transmitted.

MIDIClk: MIDI Clock will be transmitted.

SyncTr: MIDI Clock data recorded on the sync track will be transmitted.

MTC Type

This sets the type of MTC. Check the specifications of the MIDI devices that you are using, and select the appropriate type of MTC on the VS-880.

30:30 frames per second non-drop format. This is used by audio devices such as analog tape recorders, and for NTSC format black and white

video (used in the US and Japan, etc.).

29N: 29.97 frames per second non-drop format. This is used for NTSC format color video (used in the US and Japan, etc.).

29D: 29.97 frames per second drop format. This is used for NTSC format broadcast color video (used in the US and Japan, etc.)

25:25 frames per second frame rate. This is used in SECAM format / PAL format video (used in

Europe, etc.), and for audio equipment and film.

24:24 frames per second frame rate. This is used for film in the US.

<Non-drop format and drop format >

NTSC format VCRs use two formats; non-drop and drop. In non-drop format, the frames are continuous. However in drop format, two frames are skipped at the beginning of each minute except for the minutes which fall at ten- minute intervals.

In most video production and music production, continu- ous frames are easier to handle, so non-drop format is widely used. However in broadcast studios, where time code must match actual clock time, drop format is widely used.
