Chapter 5 Using MIDI
 
MIDI, an abbreviation for Musical Instrument Digital Interface, is a 
universal standard that enables musical instruments to exchange 
musical performance data, messages concerning changes in the 
sounds, and other information. Any device that conforms to the 
MIDI specifications can communicate (to the extent that is relevant 
to both devices) with any other MIDI device, even those that were 
made by a different manufacturer or that belong to a different 
category of instrument. 
Under the MIDI specifications, performance data produced by such 
actions as playing a keyboard or pressing a pedal is handled as MIDI 
messages.
Using MIDI, you can carry out the following operations with the VB-
99.
 
 
 
*
Use of MIDI requires that the MIDI channels of connected devices 
be matched.
 
Data cannot be transmitted to or received from other MIDI devices 
unless the MIDI channels are set correctly.
 
Operating from the VB-99
 
Outputting Program Change Messages
 
When a patch is selected with the VB-99, the VB-99 simultaneously 
transmits a Program Change message corresponding to the selected 
number. The external MIDI device switches its settings in response 
to the received Program Change message.
 
Outputting Control Change Messages
 
Data describing the action of an external device (expression pedal or 
footswitch) connected to the VB-99 is output as Control Change 
messages. These messages can be used for such tasks as adjusting 
external MIDI devices’ parameters.
 
Outputting Performance Data
 
The bass’s performance data can be output as Note messages and 
Bend messages, allowing you to perform through synthesizer sound 
modules and other devices connected to the VB-99. For more 
detailed information, refer to 
 
 
 
Transmitting Data
 
You can use Exclusive messages to transmit settings for effect 
sounds and other data stored in the VB-99 to other MIDI devices. 
This allows you to give another VB-99 the identical settings and to 
save effect sound settings to MIDI sequencers and other such 
devices.
 
Controlling the VB-99 from an 
External MIDI Device
 
Switching Patch Numbers
 
The VB-99’s patches switch immediately in response to Program 
Change messages received from external MIDI devices.
 
You can set the correspondence between MIDI Program 
Change messages and the VB-99’s patches with the 
 
 
55). Set this to ensure correspondence of the VB-99’s 
effect sounds with those of other MIDI devices.
 
The connections shown in the diagram below are used when playing 
your bass backed by an automatic sequencer performance. The VB-
99’s patches change automatically when a Program number is 
entered with the performance data at the point where you want the 
VB-99’s patches to change.
