MIDI continuous controllers may seem confusing at first, but they are really very 
simple once you understand them. You probably already know that there are 16 
MIDI channels per MIDI cable. Information on a MIDI channel will only be 
received by an instrument set to receive that channel. MIDI channels are usually 
associated with different sounds. In this way, up to 16 sounds per MIDI cable can 
be separately controlled.
Each MIDI channels uses three basic types of messages; note on/off, preset 
changes, and continuous controller messages. When you play the keyboard, the 
Xboard transmits information about which notes were played and how hard.
The Xboard can also send continuous controller information from its 16 knobs, pitch 
and mod. wheels as well as aftertouch from the keyboard (key pressure applied after 
the notes have been pressed). These controls are used to add more expression or 
control.
The controller knobs send out information on separate continuous controller 
numbers. There is a set of 128 continuous controller numbers (0-127) for each 
MIDI channel. Some continuous controllers, such as modulation wheel, volume, 
and pan have standardized numbers. For example, volume is usually sent on 
continuous controller #7.
Normally, the Xboard controller knobs and wheels transmit on a single MIDI 
channel, but each of the 16 knobs and wheels can be programmed to transmit on 
a different MIDI channel if you so desire. See 

 for more information.
