#imitation Volca Keys Patches

The thing that gives it a tom sound is the EG with a short delay/release acting on the VCO pitch, making the pitch fall quickly with each note.

This creates a flute-like sound by oscillating a relatively low cutoff value to create a vibrato effect. The slow attack and delay make it seem more natural. Slight detune gives it some body. Turn peak up to boost the lower frequencies if you want.
