Lowpass Filter
The pages for lowpass and highpass are identical except for their filter type. Each is based on Supercollider's 12dB/octave SVF filter.
The filter also has an LFO available, with selectable waveform, rate and range.
Control Modes
There are 2 different control modes for the filter, set by K2 (CTRL):
Filter
| Control | Function | Description |
|---|---|---|
| K2 | CTRL | Switches control mode |
| K3 | Filter mix (OFF / 50% / ON) | Provides control over filter routing.OFF passes the dry signal only and switches the filter off. The 50% setting routes half of the signal through the filter. ON routes the full signal through the filter. |
| E2 | Frequency (20Hz-20kHz) | Sets the filter cutoff frequency |
| E3 | Resonance (0 - 0.98) | Controls the filter resonance |
LFO
| Control | Function | Description |
|---|---|---|
| K2 | CTRL | Switches control mode |
| K3 | LFO waveform | Selects the LFO waveform shape |
| E2 | LFO rate | Synced to clock; 1.00 = 4 beats |
| E3 | LFO range (0-16, unipolar) | Implemented using frequency * 2^range |
