Create new automation envelope with each take?

Does the Guitar Port VST Plugin actually process audio or does it just control the hardware Guitar Port? Sorry, I had to ask because I'm not familiar with it.

Just a thought... Maybe try installing Gearbox. From what I've read it seems to be an upgraded Guitarport. It might solve this issue - maybe.

This really has me scratching my head... So lets test a couple of things: Record some guitar/wah licks, and then: Route the *recorded* MIDI (from the 2nd track) to a 3rd track, and arm that 3rd track to record MIDI. Disarm your original tracks, and hit the record button on the transport. - If you are sending/routing MIDI, Reaper should record the MIDI coming out of the 2nd track into the 3rd track. -If you get MIDI recorded, the problem is that your VST is not responding to MIDI (for whatever reason). -If you don't get MIDI recorded into the new track, then somehow, the MIDI routing isn't happening. We're not trying to make it "work" at this point, but trying to isolate the problem.

A breakthrough! 

VICTORY! 

The param button, yes! Glad you got it solved! The next person who has a similar issue can read about your adventures and find the solution. :)
