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.

Meaning
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

0-127
Pulsweitenmodulation 1&2, regelt absolut und nicht relativ.
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 Offset Wave
83
On: 64-127
Off: 0-63
Bitshifter. The waveform will be shifted upwards by a fixed 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.
