Hi,
Thanks the project ! 
Dear Diamondj421,
I built this protools recording light. This working almost perefectly. If i setup on protools HUI protocol receive from: arduino_midi and send to:arduino_midi, then some protools command, for example: Time stretch or Scrubb, trigger false PAN (panorama) some tracks.
I found a not nice solution: HUI: receive from:Avid003, port1 send to:arduino_midi
This setup work perfectly, but not too beautyful !
And i added some line to code, because i need a relay for domestic sound (in studio). If rec ready or rec on, relay breaks audio, and if rec off, wait 200ms and relay closed. Audio listening in studio during playback(REC NOT). This need for actor to try (or test).
Can i switch OFF the midi sends? and then i can using first HUI setup (receive and send arduino_midi)
Thanks and Regards
Laszlo
