ok, here's the thing: the Beatstep (not the Beatstep PRO) has a beastly problem - the encoders, of which there are a ton, they're meant for one thing and one thing only, to step through tiny values. So each little click is one half step, because they're meant for setting the internal sequencer. Well, this makes this unit almost completely useless as a generic MIDI controller because you can do a complete revolution of the knob and only make it through an octave and a half. That means you're scrolling for days if you map it to any normal control like a pan or a volume.
As a result, the market is full of these once $150 controllers which are now like $50 because no one wants them. This unit needs some Stray to help give it new life, some kind of interpolation script to assist with knob accelleration, and do something cool with the pads. It's a really nicely built unit, metal and high quality encoders and pads, it was just very poorly implemented. I would totally ship you my unit to use to build a script that'll redeem the life of this guy.
