Model 72 over four pages, learned in Logic Pro from the AU.

Page 1 is the filter: Cutoff, Resonance, Envelope Amount and the filter envelope's Attack, Decay and Sustain on knobs 1 to 6, feedback level on knob 7 and Doubling spread on knob 8. Buttons: Filter Mod on 1, the 33% and 66% switches (filter keyboard tracking) on 2 and 3, feedback on/off on 7 and Doubling on/off on 8.

Page 2: Osc 1 Range, Waveform and Volume, Osc 2 Range, Tune, Waveform and Volume, and Osc 3 Volume. Buttons: Osc 1 on/off on 1, Osc Mod on 2, Osc 2 on/off on 4, Noise Colour on 7 and Osc 3 on/off on 8.

Page 3: Osc 3 Range, Tune and Waveform, Noise Volume, Master Tune, LFO Rate, Mod Mix and Glide. Buttons: Osc 3 keyboard tracking on 1, Osc 3 on/off again on 2, Noise on/off on 4, Noise Colour again on 5, LFO Waveform on 6, Noise/LFO on 7 and Legato on 8.

Page 4 is the amp envelope: Attack, Decay and Sustain, with the Release switch on button 1.

The Range and Waveform knobs click through all six positions but are not labelled, so the plugin's panel shows which one you are on.
