Region Modes / Sliders / Knobs
[ SOLO | STEP | RAND ]
- SOLO is the default mode and scans the entire region
- STEP subdivides the region and steps through divisions sequentially at the Dur rate
- RAND subdivides the region and steps through divisions randomly at the Dur rate
(Brightness) Darken the region to effectively attenuate the gain of a region (useful when mixing several regions)
(Blur-Sharpen) Below 0.5 = smooth noise/partials | Above 0.5 = enhance noise/partials
(Downsample) Pixellate image == audible bit-reduction
(Tremolo Depth) Amount of brightness modulation to apply == audible tremolo
(Tremolo Rate) Rate of brightness modulation == audible tremolo rate
