ROYGBIV Bass
The bass from Boards of Canada’s ROYGBIV.
The FM amount on VCO-A should be quite subtle. If you notice, its probably too much.
Try attenuating two different LFOs with the Mixuverter and VCA-B. Then sum, and patch the result to VCO-A FM-2 and VCF FM-3.
Also try setting VCF mode to LP1 or 2 for more growl.
