Midi Commands inter app

  • Hello, guys!
    I'm new with MIDI stuff, and you guys know how hard it is to learn all the operational stuff.
    I'm struggling for weeks trying to use Bias Fx with an App called Set List Maker.
    I use Set List Maker live to trigger backing tracks, so I can play guitar and sing over them.
    Recently ive dsicovered the app have the hability to send and receive MIDI commands, and it can do automation too. For example: I can create an automation in a song, so in the chorus the distortion pedal turns on automatically, and so on.
    I am able to make bank changes, but I can't make control commands like turn on/off a distortion inside a bank...
    Do you guys know how can I do it?
    Sorry for my bad english.
