Suggestions: 1) Use the Feedback parm in the VCA section for
distortion effects and/or 2) the Noise parameter in the MIX/VCF
section. If that's not noisy enough then 3) Crank up the FM Depth
parm in the Sync/FM section.

Remember, the FEG Depth setting interacts with the Filter Cutoff
value - make certain to adjust it when if you drastically reduce the
FC downwards.

Why?

Try raising the Filter Cutoff value in this instance.
