UPDATE: On the audio track, if I right click a block, select controller assign and select a knob, then go to logic settings, control surfaces, controller assignment and step on a fcb1010 switch, it will work! This way, like on the real Helix machine, yoi have to assign the block byoass for each patch. The same way you have to program the snapshot in every patch. Snapshot from the syx file work on the midi track, the procedure i wrote works on the audio track in realtime. Probably the correct way is in between! I'll keep trying and let you know
