On Axe-FX II this worked properly, there was an on and off value.
I think that even the third party MIDI spec for the III states that the SysEx commands don’t set the state but rather simulate footswitch press event.
doesn’t matter what you send. What it does depends on previous state. There’s no on or off value. That was the reason why I ended up not using Axe-FX III live.Send a single value on separate CC#'s and Play and Stop work as expected. The trick is to send only the "On" value for the button or switch on press and no "Off" value on release.
