a little improvisation i did after improving the LFO phase modulation and arpeggiator functions of the Mellotronium: an ATMega328P-based mirco-synthesizer. there are plenty of improvements to be made, but it’s surprising how much you can make of these microcontrollers do. combined with a Roland RC-50, it’s music composition on the fly.
you’ll have to excuse the loud hissing noise. apparently the power supply of my netbook isn’t exactly quiet. it sounds a lot better using the battery pack or the wall wart.
