This is a draft cheat sheet. It is a work in progress and is not finished yet.

Suggested Initial Position

Start Knob - Controls Audio Offset

Fully CCW
Start of file
Fully CW
End of file
Start CV input range: -5V to +5V

Speed Knob - Controls Playback

CCW: Backwards
CW: Forward
LED Unlit: Frozen
White: /8
Blue: x1
Orange: /4
Green: x2
Yellow: /2
Violet: x4
Press Encoder
Reset to defaul­t(press again for reverse default)
Press and Hold
Enter instrument select mode
Speed CV input range: -5V to +5V

Size Knob - Audio Sample Length

Size is relative to original sample length. If Size is larger than length determined by start knob, then entire length will loop. Further increase of Start results in length decrease regardless of Size knob.
Size CV input range: -5V to +5V
  

Blend Knob - Controls Engine Mix

File Mode (Source LED Off)
CCW
Phase Vocoder Only
CW
Mixes in granular engine
Live Mode (Source LED On)
CCW
Mixes in phase vocoder
CW
Mixes in granular engine
Blend CV input range: -5V to +5V

Pitch Knob (Indep­endent of Speed)

LED Blue: Original Pitch
CCW - Decrease
CW - Increase
Yellow: -1 Octave
Green: +1 Octave
Orange: -2 Octaves
Purple: +2 Octaves
White: -3 Octaves
 
Press encoder
Reset to default
Press and hold, turn
Jump octaves
Pitch CV input range: -5V to +5V

Overlap Knob - Grain Size / Spacing

Adjusts the size of the grains, as well as the amount of overlap between successive grains. As the grain size becomes larger than the space between grains (Density), the grains begin to overlap. Grain size ranges from 1% of the grain rate, to 600% of the grain rate.
Overlap CV input range: -5V to +5V

Density Knob - Amount of Grains

CCW
Single grain every few seconds
CW
Grains produced at audio rate
Density CV input range: -5V to +5V

Window Knob - Controls Envelope

Adjusts the amplitude envelope applied to each grain.
CCW
Softer
CW
Harder
Window CV input range: -5V to +5V
