FM synthesis almost always sounds great with reverb and delay. So the Circuit Tracks is a great way to juice up some FM synthesis. My only true FM synthesizer is the Korg Volca FM. So I ran a cable into the first input and started this jam with the dry sound (with some playful filter sweeping). The Circuit is also sequencing it since it has so much more in terms of sequencing power. Then I get the Volca FM nice and wet with those tasty send FX. Finally I start bringing in the other elements from the Circuit Tracks via it's own synth and samples. I hope you enjoy!
