Parameters 18
| Name | Type | Range | Behavior |
|---|---|---|---|
| Aliasing | menu_setting | 0% – 100% | Progressively disables anti-aliasing technology to introduce aliasing artifacts; at 0–25% only upward pitch-shift aliasing is affected; beyond 89% extreme alias mode emphasizes aliases.869 |
| Attack Time | menu_setting | 0s – 99s | Sets how long the envelope takes from gate/trigger receipt to reach full level; can be modulated by CV inputs.869 |
| Bit Depth | menu_setting | 1bit – 32bit | Reduces effective bit depth of playback from 32 down to 1 bit (including fractional bits from 1.0 to 10.0) for lo-fi degradation; can be modulated by CV inputs.869 |
| Channel Mode | menu_setting | — | Selects how a channel responds to triggers and interacts with other channels; options are Master, Link, Stereo/Right, and Cycle.869 |
| Crossfade Width | menu_setting | 0.01V – 10V | Controls the voltage range over which crossfades between Crossfade Group members occur; small values yield sharp transitions, large values yield gradual overlapping transitions.869 |
| Level | menu_setting | -90dB – 6dB | Sets initial channel output level; supports linear and exponential amplitude modulation via CV inputs.869 |
| Loop Mode | button | — | Three-position button cycling through Loop Off, Normal (loop repeats while gate high, stays in loop during release), and Gated (loop exits on gate fall, plays to end during release).869 |
| Loop Start | menu_setting | — | Sets the loop return point; can be modulated by CV from -1.00 to +1.00; minimum loop length is 4 samples.869 |
| Mix Output Level | menu_setting | -89.9dB – 6dB | Sets channel level in the mix output independently from the individual output level; setting to Off removes channel from mix entirely.869 |
| Pan | menu_setting | -1 – 1 | Sets the stereo position of the channel in the mix output; can be modulated by CV from -40.0% to +40.0% per volt.869 |
| Phase Modulation Index | menu_setting | 0 – 1 | Sets the intensity of the selected phase modulation source; can be modulated by any CV input with gain from -51.2 to +51.2 samples per volt.869 |
| Pitch | menu_setting | -8octave – 5octave | Sets the initial transposition of a channel relative to the originally sampled pitch; can be exponentially modulated by any CV input with gain from -2.00 to +2.00 octaves per volt.869 |
| Play Mode | button | — | Cycles through 1 Shot mode (sample plays to end on trigger), Gate mode (sample plays while gate is high), and allows Latch mode via button hold; affects all zones on a channel.869 |
| Release Time | menu_setting | 0s – 99s | Sets how long the envelope takes to decay to zero after gate fall; can be modulated by CV inputs.869 |
| Sample End | menu_setting | — | Sets the playback stop point within the sample; position can be modulated by CV inputs with gain from -1.00 to +1.00; positive CV moves end toward end of sample, negative toward beginning.869 |
| Sample Start | menu_setting | — | Sets the playback start point within the sample; position can be modulated by CV inputs with gain from -1.00 to +1.00; positive CV moves start toward end, negative toward beginning.869 |
| Sampling Level | menu_setting | -30dB – 24dB | 869 |
| Sampling Time | menu_setting | 0.1s – 600s | 869 |
