"GVCO"

"GVCO" [mp3 removed -- please listen on Bandcamp]

Using the Doepfer A-155 to make a "graphic VCO" - essentially a sequence of LFO signals played at audio rate to make a custom waveform.
I also played the steps at a slower speed to make tunes. The result was then treated with some voltage controlled effects and massaged in Ableton. Then drums and some softsynth riffs were added.
