Some videos of the synthesizer that was built during the 3-day synth-jam in Malmö 2011.
It consists of an Arduino with midi-shield, and a switch capacitor filter.
At first it had a nice 4-oscillator super-saw playing monophonically.
Later, 4 note polyphony was added, for a total of 16 oscillators!
At the end of Sunday it also had portamento, volume envelope, oscillator spread and pitchbend! All controlled via MIDI-CC.
Full schematics and source code soon avalible on
