the 12 Step definitely sends CC as well - pressure, tilt, velocity... It's a really nice controller for CC.
I've been using it hooked up to Live to play pad parts and it's SO good - the CC control allows me to morph the sounds a little, adds a random musical element that's not just on/off. Am going to have lots of fun with that...
the bit that still looks like it's impossible in this version of the firmware is to assign a different CC channel to the tilt or pressure on each button - so I can't have volume on one, feedback on another, pan on another... It's programmed by scene (which makes perfect sense if you're using it for what it's designed for!).
But, I am going to set up a few banks of LP1 controls on it using the note on/off triggers, so I've got a back-up, and don't have to ever go back to using my old pre millennial midi controller again
I think I'm going to try out the 12 Step playing pads + bass idea on a gig soon. It has lots of potential
