The first minute, if not both parts, of this song came from submissions to some of the Battles earlier this year. I remember one seemed to revolve around the semi-hidden Iter synth which I pushed into all sorts of strange feedback. The second half has a lot of fun with the delay effect, random LFOs, short delay times, and who knows what else.
I like this track as just more proof of the OP-1’s wonderfully peculiar personality. Nothing else out there is going to make this.
Some light effects (reverb mostly) added in Logic afterwards.
