Chapter 15 Using External MIDI Devices

Adjusting Effects

You can use MIDI Control Change messages transmitted from an external MIDI controller to control effects.

1.Press [PLAY (DISPLAY)].

2.Hold [SHIFT] and press [F5 (SYSTEM)]. The System menu icon appears in the display. If the System menu icon does not appear, press [F6 (EXIT)].

3.Press [F4 (MIDI)]. If “MIDI” does not appear in the display above [F4], press [PAGE] until “MIDI” appears, and then press [F4 (MIDI)].

4.Use[ ], [ ], [ ], and [ ] to move the cursor to “Control Type” and use the TIME/VALUE dial

to select “C.C.”

Control Type

This selects the type of MIDI messages that will be used when transmitting mixer settings to an external MIDI device, or when MIDI messages from an external MIDI device are used to control the mixer.

Off: MIDI messages related to mixer operation are not transmitted or received.

C.C.: The mixer is controlled using Control Change message.

Excl: The mixer is controlled using Exclusive messages.

5.Use[ ], [ ], [ ], and [ ] to move the cursor to “C.C.Eff,” and use the TIME/VALUE dial to

select “On.”

C.C.Eff (Control Change Effect)

With this set to “On,” the effect is adjusted when control change messages are received.

6.Press [PLAY (DISPLAY)] to return to the Playlist display.

*If you wish to use Control Change messages to edit effects, use NRPN (Non Registered Parameter Numbers). For more information, refer to the “MIDI Implementation” (Appendices p. 82; NRPN references begin on Appendices p. 83).

MIDI Machine Control

The VS-1824 supports MIDI Machine Control (MMC). This means that when two VS-1824s are synchronized, or when a VS-1824 is synchronized with a MIDI sequencer that also implements MMC, operations such as Play, Stop, Fast Forward, etc., can be accomplished by operating only the Master device.

MMC messages include transport control functions and location information, but not actual synchronization signals. Synchronizing with MMC is done in a loop configuration, with an MMC master device sending the command to start the MMC slave device which, in turn, sends sync signal (usually MTC or MIDI Clock) back to the MMC master device. An MMC setup requires two-way MIDI communication and the proper setting of the following parameters on the VS-1824: Device ID, MIDI Out/Thru, SysEx RX, SysEx Tx, MMC Mode (Master, Slave, or Off), Sync Gen, and Internal Clock. For more information on these settings, take a look at the synchronization example using Cakewalk and the VS-1824 (p. 210).
