System setting
MIDI
The VGA-7 uses the following MIDI messages.
• Program Change messages transmit commands for
switching Patches.
• “Control Change” messages, which can be used to
convey changes in various effects, control the volume,
and switch effects on/off.
• “System Exclusive” messages (carrying data specific to a
particular device), used to save patch data on an external
device, or to reload patch data saved on an external
device back into the VGA-7.
About MIDI Channels
MIDI has sixteen channels 1 – 16, and MIDI messages will be
received by the instrument (the receiving device) whose
channel matches the channel of the transmitter.
When the Omni mode setting on the receiving device is set to
ON, then MIDI messages can be received, regardless of the
MIDI channel of the sending device.
* Factory settings have the MIDI channel set to Channel 1 and
Omni mode ON.
* The MIDI channel and Omni Mode settings can be modified.
(p. 48)
Program Change
“Program Change” is a MIDI message that is generally used
to switch Patches.
The VGA-7 uses Program Change messages to select patches.
By connecting a MIDI foot controller such as an FC-200 (sold
separately), you can use your feet to transmit Program
Changes and select patches. (refer to p. 43)
Transmitting/receiving VGA-7
settings
VGA-7 user patches / divided pickup settings / system
settings can be transmitted as MIDI exclusive data to an
external MIDI device, and this data can be re-transmitted
from the external MIDI device back to the VGA-7.
The action of transmitting MIDI exclusive data is called bulk
dump , while receiving it is called bulk load .
By using a MIDI sequencer that is able to record exclusive
data, you can transmit data to the MIDI sequencer and save it
on floppy disk or other media. Alternatively, you can directly
connect two VGA-7 units via a MIDI cable, and transmit or
receive parameters directly.
* Even if the MIDI channel is set to “Omni ON,” Exclusive
messages cannot be received if the Device ID differs.
Be sure to match the Device ID when sending and receiving
data. (refer to p. 48)
The Device ID is set to “1” at the factory.
BULK LOAD
Receives the VGA-7’s data from an external device.
Connection Examples:
Receiving settings that were stored on a sequencer
fig.48
* For details on sequencer operation, refer to the owner’s manual
for your sequencer.
Receiving all settings from an external device
To receive data that was transmitted via Bulk Dump (p. 41)
with the “1 ALL” or “2 PATCH (ALL)” setting, use the
following procedure.
1. Select the Parameter Number: 6 LOAD.
2. Send the data from the transmitting device (sequencer).
While the data is being received, the following display
will appear.
fig.49
3. When this display disappears,
press [SELECT/VALUE ▲] (EXIT) to end the procedure.
The display will indicate “U01.”
* If you press [TUNER], [VARIATION/EDIT], [GK], or
[SYSTEM] instead of pressing [SELECT/VALUE ▲] (EXIT),
you are returned to where you were before [SYSTEM] was
pressed, and the data existing before the load will sound until
you change patches.
