Bleepotron

Another machine joins the merry throng.

The Bleepotron is a MIDI synth kit that uses a dsPIC digital signal processor. It's a very easy build and has a great lo-fi sound. It's even possible to edit patches and save on it!

I housed mine in an old vid box.

I ran through all it's presets sounds here.

(sorry about the crap loop)
