1: Classic square wave (pulse) form - [PWM 1] is adjusting.
2: Combined by A and B - [PWM 1] adjusts A, [PWM 2] adjusts B.
3 and 4: Complex square wave forms - [PWM 1] adjusts lower half wave,
[PWM 2] adjusts upper half wave.

ADSR Attack 17 or 73 0-127 Rise time of the ADSR envelope generator.
ADSR Decay 19 or 91 0-127 Decay time of the ADSR envelope generator.
ADSR Sustain 21 or 93 0-127 Holt level of the ADSR envelope generator.

PWM 1 25 or 76 0-127 Pulse width modulation 1, will be overwritten by [PWM 1&2].
PWM 2 23 or 95 0-127 Pulse width modulation 2, will be overwritten by [PWM 1&2].
PWM 1&2 10 0-127 Pulse width modulation 1&2, controls in absolute and not in relative
terms.
OSC Volume
(Pre Filter Volume)
20 or 92 0-127 Oscillator maximal level. The velocity and the envelope generator
(ADSR) modulate the volume to a maximum level set here.
DC Oset Wave 83 On: 64-127
O: 0-63
Bitshifter. The waveform will be shifted upwards by a xed level set
here. As soon the upper limit is reached the truncated part will be
inserted at the lower limit again. Thereby distorted and destructive
sounds can be generated.
