Hi guys, We've been working on a module at uni for experimental music systems and having great difficulty working out how to assign presets and the likes to midi as well as volume levels. Just can't get our heads around it. We have lent a Novation Zero sL MkII controller and would ideally like to assign the levels and the preset buttons to different controls and was wondering if anyone could lend a hand in laymans terms?

I've attached the patch for reference. Much appreciated
