I use Ableton live a lot to jam and to DJ, and using the mouse to
control all the parameters got in the way quite often. You can’t
select a scene and turn a knob at the same time, switching between
views was tiresome. I first thought about building a midibox, but then decided to build my own midi system
using an AVR microcontroller, which I’m more used to. Blueloop helped me a lot
with the schematics, showing me a nice trick to control LEDs using the
same matrix as for the switches (this is not integrated yet,
though).
