Chapter 5 Using MIDI
 
Receiving Control Change Messages
 
The VB-99 can receive Control Change messages to 
control specified parameters while a performance is in 
progress. Set the parameters to be controlled with 
 
 
 
Receiving Data
 
The VB-99 can receive data transmitted from other VB-99’s and data 
saved to MIDI sequencers.
In order to be able to convey the full range of expression that is 
possible during performance, MIDI provides for different types of 
MIDI messages. MIDI messages can be categorized broadly into two 
groups; messages handled on an individual MIDI channel basis 
(Channel messages), and those handled independently of MIDI 
channels (System messages).
 
Channel Messages
 
These are messages used for conveying the events that take place 
during performance. Normally, you can control most performances 
using only these messages. The action controlled with each MIDI 
message is determined by the receiving device’s settings.
 
Program Change Messages
 
These message are generally used for switching sounds; sounds are 
switched with Program Change numbers 1–128. Furthermore, with 
the VB-99, you can also use Control Change Bank Select messages 
together with the Program Change messages, allowing you to switch 
400 different patch numbers.
 
Control Change Messages
 
Control Change messages are used for enhancing performance 
expression. Functions are distinguished from one another with 
Control numbers; the particular functions that can be controlled 
varies with the MIDI device. With the VB-99, you can control 
specified parameters.
 
Note On Messages
 
These messages convey to the device the pitches and volumes at 
which sounds are played.
 
Note Off Messages
 
These messages instruct the device to stop sounds currently being 
played.
 
Bend Messages
 
These messages are sent to produce continuous changes in the pitch.
 
System Messages
 
System messages include Exclusive messages, messages required for 
synchronized performances, and messages designed to prevent 
problems with operation.
 
Exclusive Messages
 
Exclusive messages are used for handling sounds unique to a 
particular device and other such messages. Basically, you can 
exchange messages between devices of the same type from the same 
manufacturer. Using Exclusive messages, you can store parameter 
settings to sequencers and transmit parameter settings to other VB-
99s.
To exchange Exclusive messages, the Device ID numbers for each of 
the instruments must match.
