| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (2) | |||
| CV IN | cv | — | Cutoff CV input. Voltage applied here modulates the filter cutoff frequency, scaled by the CV IN attenuator knob. Manual caption: "Patch cutoff CV signal here".431 |
| IN | audio | — | Audio signal input. Erica Pico Series modules have input protection against overvoltage. Manual caption: "Patch audio signal here".431 |
| Outputs (1) | |||
| OUT | audio | — | Filtered audio output. The VCF response (LP or BP, selected by the mode switch) is applied to the audio at IN; can self-oscillate at high resonance settings. Manual caption: "This is VCF output".431 |
