Roland VS-1680 Instrukcja Właściciela Pobierz pdf (Strona 128)

This chapter describes the MIDI messages that can be

handled by the VS-1680 and the operations that the

VS-1680 can perform using MIDI messages.

For more detailed information about MIDI, please

refer to “About MIDI” (Appendices p. 4).

Synchronizing with MIDI

Sequencers

The VS-1680 can be operated in synchronization with

a MIDI sequencer. Refer to the owner’s manual for

your sequencer in conjunction with this manual.

There are two main ways to accomplish synchroniza-

tion, one is method using MTC (MIDI time code)

and the other one is method using MIDI Clock, with

MIDI Clock further divided into two types, Sync

Track and Tempo Map, either if which can be select-

ed. Use the method that is appropriate for your situa-

tion.

MTC (Appendices p. 64)

• Using MTC (MIDI time code) (p. 128)

• Using the sync track (p. 131)

• Using the tempo map (p. 133)

Items Necessary for Synchronization

- VS-1680 (1)

- Internal IDE hard disk (HDP88 series)

- Audio equipment to be connected to the MASTER

jack, or stereo headphones

- External MIDI sequencer or computer sequencer

software (such as Cakewalk Pro Audio)

- MIDI cables

Master and Slave

When synchronizing the VS-1680 with a MIDI

sequencer, the device that sends, or transmits MTC or

MIDI Clock and acts as the reference device is referred

to as the master. Conversely, the device that receives

the MTC or MIDI Clock signals from the controlling

device is called the slave.

When using MTC, you can choose whether to have the

MIDI sequencer be the master that controls the VS-

1680, or to have the VS-1680 be the master that con-

trols the MIDI sequencer. In contrast, when you use

MIDI Clock, whereas you can synchronize a MIDI

sequencer from the VS-1680 (VS-1680 as master), it

will not be possible to synchronize the VS-1680 from

the sequencer (VS-1680 as slave).

Using MTC

This section explains how the VS-1680 can be synchro-

nized with a MIDI sequencer that implements MTC

(MIDI Time Code). When using MTC, you can choose

to have the VS-1680 be the master that controls the

MIDI sequencer, or to have the MIDI sequencer be the

master that controls the VS-1680.

Frame (Appendices p. 63)

NTSC Format (Appendices p. 64)

SECAM/PAL Format (Appendices p. 64)

MTC Type

The VS-1680 can work with the following types of

MTC. Check the specifications of the MIDI

devices that you are using, and select the appro-

priate type of MTC on the VS-1680.

30: 30 frames per second non-drop format.

This is used by audio devices such as ana-

log tape recorders, and for NTSC format

black and white video.

29N: 29.97 frames per second non-drop format.

This is used for NTSC format color video.

29D: 29.97 frames per second drop format. This

is used for NTSC format broadcast color

video.

25: 25 frames per second. This is used for

SECAM or PAL format video, audio equip-

ment, and film.

24: 24 frames per second. This is used for

video, audio devices, and film in the US.
