THE NEED I HAD The problem is easy to understand: I wanted to drop my PC keyboard + mouse during live performance in order to be focused on music/sound/live. The only way to solve my problem was to use an hardware to control Ableton Live, but not only that, I need a feedback from it too. But I need a lot of pots/knobs, a lot of multicolor lights, a lot of buttons... I need a big hardware without multifunctional knobs, sub-menu you have to choose to change the function of this button etc etc
