Remote MIDI Control of the VS-2000
The VS-2000 can be controlled from an external MIDI device. Three types of MIDI
messages can be used for this purpose. You can use:
•
System Exclusive (“SysEx”) messages
—that can control most VS-2000 functions.
• Program Change and Bank Select messages
— to select scenes and effect patches.
•
Control Change m
essages—that adjust important input channel, track channel, FX
return channel, Aux and FX bus, Direct path, MASTER bus and MONITOR bus
parameters. You also can adjust effect and other parameters using NRPNs.
Remote Control of the VS-2000 with SysEx Messages
You can control the VS-2000 using SysEx messages in either of two ways.
Create SysEx Messages Manually
You can manually program the SysEx messages in an external MIDI device for
transmission to the VS-2000. This method requires an in-depth understanding of MIDI
programming—see the
VS-2000 Appendices
for details.
Capture and Return SysEx Messages
Every VS-2000 button-press, knob turn, fader move and so on can generate a SysEx
message that you can transmit from the VS-2000’s MIDI OUT/THRU connector. This
data can be captured by an external MIDI recording device and transmitted back to the
VS-2000. When you’re using the VS-2000 with a sequencer—as described later in this
chapter—the sequencer can record
any
actions you perform on the VS-2000, going
beyond even the extensive automation capabilities of the VS-2000’s Automix feature.
When the sequencer plays back, your moves are faithfully reproduced.
To transmit SysEx data from the VS-2000:
1. Using a MIDI cable, connect the VS-2000’s MIDI OUT/THRU jack to the MIDI IN
jack of the device in which you want to capture the VS-2000’s SysEx data.
1. Navigate to the MIDI parameter screen (Page 283).
2. Set MIDI OUT/THRU to Out.
3. Turn on the SysEx. Tx Sw (“SysEx Transmit Switch”)—this determines whether or
not SysEx data is transmitted from the VS-2000 as you operate its controls.
4. MIXER CONTROL TYPE sets the type of messages generated by the VS-2000’s
controls. Set it to Excl so that the VS-2000 generates SysEx messages.
The various types of MIDI messages are described in the
VS-2000 Appendices
. In the
Appendices
, System Exclusive messages are called “Exclusive” messages.
When sending and receiving SysEx or Control Change messages that control the
VS-2000, take care to avoid MIDI loops. In a MIDI loop, the same MIDI messages are
sent and received by the connected devices over and over, spiraling into nonsensical
settings in either or both devices. In many sequencers, a Thru feature passes MIDI data
back to the device from which it came—this feature should be turned off when working
with VS-2000 SysEx and Control Change messages.
NRPN
You can also store VS-2000 settings in an external MIDI device using the
VS-2000’s SysEx bulk dump capabilities—see Page 288.
