The oscillators can be modulated by the LFOs or the ADSR envelope generator. The two LFOs include controls for rate and waveshape: ramp, reverse ramp, triangle, sine, square, delay; and there is also a Sample + Hold feature. The two multi-mode filters include hi-pass, low-pass, and band-pass filtering with cutoff, resonance, keyboard tracking, envelope sensitivity (AR, ADSR or preset) and modulation (ramp, sine, square, s+h) controls plus an additional band-pass-only filter.
