Ctrl & Prog Commands

[HarleyRider]

Within the Multipad creation Edit section (also true within Styles), I can change and add notes.  Using the Filter selection I can view additional commands such as Ctrl, Pitch Bend, and other commands.  I can then view and change these commands.  But I can not find any info on what the various Ctrl and Prog commands are.  For example, I can enter a Ctrl 7 and a "volume" description shows.  I can then adjust the volume of the entire multipad.  Where can I find additional information about the values of these Ctrl and Prog settings.

At this moment, I would like to create a multipad button that when depressed will play a guitar B note and pitch bend it up to a C note.  Can this be done, and if so, how?  Perhaps there are a lot of interesting things that could be done if I only knew how.
