The Beefinator !
I have looked at your beefinator youtube clips a few times, its a great looking/sounding machine.
Its an Arduino synth engine driven through midi isn't it ?
I am also interested in audio projects, as part of my recent order I added a ribbon controller and some analog joysticks to build a novel interface for the well known Auduino synth.
I also have this ongoing very un midi keyboard project, it has a pretty powerful four oscillator synth engine where each oscillator can trigger, amplitude modulate or Frequency modulate any other oscillator, I just don't have a user interface that shows it off yet - or any musical talent, I am getting on there on the fist part, not so much on the talent part though.
