DR2
drum synthesizer with an extra wavetable shaper to add higher harmonics to the sine-base. Uses wavetables made with the wavetable creator "Creator" (1024 waves of 1024 samples long each) Seperate envelopes for pitch, volume and noise levels. Volume envelope can be fed to the end-LP filter (E2C knob) Noise part has it's own SVF filter with cutoff, resonance and selectable mode(LP,HP,BP,NOTCH) Best to trigger this with a trigger instead of a gate.
