 Using the same proprietary Roland "fundamental generator" chip, the possible waveforms include 16' pulse, 8' pulse, and sawtooth waveform.The -24 dB per octave voltage-controlled filter is self-oscillating, with string-pitch tracking.In addition to the same ADS Envelope Generator found in the Polyensemble and Bass, there is a triangle wave LFO to modulate pulse width or the filter cutoff.
