First Cut OP-1 by bkbirge published on 2012/01/13 08:11:24 +0000 After about 2 hours learning the functions on the OP-1 here's the first track I've made with it, this is a cool little workstation synth for sure. Those of us that grew up in the era of cassette 4 tracks will be comfortable with the workflow, fun stuff. 4 tracks. Drum pattern from grid sequencer on left, same pattern on right but pitched half step lower. 3rd track is bass/synth and 4th track is the string synth engine with heavy spring reverb.
