i can send the session with just the midi track. i think mine only worked because i had the wah pedal selected. i am still not sure how to send data that does something like:
select a specific performance, select a particular slot and THEN select the Stomp. make the changes.
I am putting together a small reaper session with what I did to control the wah but for some reason it is not working now.
It might be my MIDI connection. My sound card (Lynx Aurora) does not have a full MIDI implementation so I am using one of the PoS USB to MIDI convertors.
