| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (3) | |||
| FREQ CV | cv | -10V to 10V | CV input for cutoff frequency; added to the FREQ knob position and scaled by the ATTEN attenuverter. Tracks 1V/oct across up to four octaves.1065 |
| INPUT | audio | -5V to 5V | 1065 |
| RES CV | cv | -5V to 5V | CV input for resonance; voltage is added to the RES knob position.1065 |
| Outputs (1) | |||
| OUTPUT | audio | -5V to 5V | 1065 |
Parameters 3
| Name | Type | Range | Behavior |
|---|---|---|---|
| ATTEN | knob | — | Attenuverter that scales and optionally inverts the FREQ CV input signal. Far left passes 0V to -10V; far right passes 0V to +10V.1065 |
| FREQ | knob | — | Sets the filter cutoff frequency, also known as the corner frequency or -3dB down point.1065 |
| RES | knob | — | Sets the resonance (Q) of the filter; when turned fully clockwise the filter self-oscillates, producing a pure sine tone at the frequency set by FREQ.1065 |
