Pony VCF
Space-conscious lowpass filter and volume processor. A combination of VCF + VCA + Mixer that lets you mix three different sound sources and shape their tone and levels. Built around the SSI2144 FATKEYS chip with temperature-compensated Q and frequency, and resonance-compensated volume.330

Capabilities 3
- Low Pass VCFvcf-lowpass
- 330
- Mixermixer
- Three audio inputs each attenuated by individual faders and then summed before the filter. Output normalized to IN3 for feedback.330
- Voltage-Controlled Amplifiervca
- Integrated VCA located at the end of the signal chain after the filter, controlled via Volume CV IN with normalization from CV1 Mode Switch.330
Jacks 8 — 7 in / 1 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (7) | |||
| Audio IN 1 | audio | — | 330 |
| Audio IN 2 | audio | — | 330 |
| Audio IN 3 | audio | — | Audio input 3. The module output is normalized to this jack for easy feedback patching.330 |
| CV1 | cv | — | Controls Cut-Off and/or VCA Volume depending on CV1 Mode Switch setting.330 |
| CV2 | cv | — | Controls the filter Cut-Off frequency.330 |
| Resonance CV IN | cv | — | 330 |
| Volume CV IN | cv | — | Controls VCA volume. When nothing is plugged in, normalized from the CV1 Mode Switch (either CV1 signal or 10V constant).330 |
| Outputs (1) | |||
| Audio OUT | audio | — | Main audio output. Normalized to Audio IN 3 for feedback patching.330 |
Parameters 7
| Name | Type | Range | Behavior |
|---|---|---|---|
| Audio Mixer Volume 1 | fader | — | 330 |
| Audio Mixer Volume 2 | fader | — | 330 |
| Audio Mixer Volume 3 | fader | — | Controls volume of Audio IN 3. The module output is normalized to IN3 for easy feedback patching.330 |
| CV1 Attenuator | menu_setting | — | Controls the amount of CV that goes from CV1 IN to the Cut-Off.330 |
| CV1 Mode Switch | switch | — | Selects what is normalled to the Volume CV IN jack when nothing is plugged in. Lower position: CV1 is sent to Volume CV so VCA only passes signal when voltage is present at CV1. Upper position: 10V is sent to Volume CV so VCA always passes signal. A jack plugged into Volume CV IN disconnects the switch.330 |
| Cut-Off | menu_setting | — | 330 |
| Resonance | menu_setting | — | Sets the manual resonance (Q) of the filter. Output level is compensated against resonance so perceived volume does not fall when resonance is raised.330 |
