Record Enable via Midi Control change from Controller??

[jallen]

Guys,

I using Pro-Tools LE 7.4 on a laptop for a live performance.

I have three instrument tracks set up. One track for Native Instruments Elektrik Piano, one track for Native Instruments B4 Organ, and one track for a Roland Sound Canvas sound module.

Depending on the song, I may have different tracks enabled or not. Sometimes, I only want the Elektrik Piano, sometimes I only want the B4 etc..

Now, I know to turn on or off tracks, I can simply hit the record enable button in Pro Tools on the lapto, but is there a way to do this via a midi control change or program change via a keyboard controller?? Any suggestions at all would be appreciated.
