I am using the Helix to control a bank of external pedals using the VooDoo Hex. I control the VooDoo Hex loops using CC messages. Of course, I can use the command center to do this, but manually assigning multiple channel / CC messages to control each loop for each snapshot (or foot controller) is tedious. I doubt live programming the Helix directly using an external app (midi or FBV) is easy (please tell me if I am wrong). Is there documentation on the .hlx JSON format? I could write an GUI editor to facilitate editing the .hlx files then upload to Helix with the Line 6 editor. I can try and use samples to reverse engineer, but it would be better to get official docs.
thanks,
mark
