That is very cool!
As an experiment, I used an olde Behringer FCB-1010 Midi board pedal and a couple Midi Solutions boxes to convert signals to sysex, etc etc.. One of the expression pedals was the throttle. The other was the brake. I then assigned the stomp-box type buttons to be the Switch toggles for the switches. It was fun!
If I had the time, I had considered using my Mainstage setup to automate a running session based on a playback music track
Your use of the Presonus unit is genius. Now I want to see if my Focusrite could do it
Or even the X-32 mixer software.
