Cinnamon
A unique-sounding state-variable filter with simultaneous low-pass, band-pass, and high-pass outputs, voltage-controlled cutoff, Drive switch for input overdrive, and Character switches to modify resonance response.185

Capabilities 3
- Self-Oscillationself-oscillation
- At maximum resonance the filter self-oscillates, producing 0°/90°/180° phased sinewaves at LP/BP/HP outputs respectively.185
- State-Variable Filterstate-variable-filter
- Simultaneous LP (12dB/oct), BP (6dB/oct), and HP (12dB/oct) outputs; Drive and Character switches modify resonance response and waveform character.185

| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (3) | |||
| INPUT | audio | — | Audio input processed by the filter; gain controlled by the Input level knob.185 |
| LEFT CV | cv | — | V/Oct CV input affecting cutoff frequency; tuned to 1V/oct standard (tracking reliable only with Character switches off).185 |
| RIGHT CV | cv | — | CV input affecting cutoff frequency; modulation depth set by the Attenuator knob (fully CCW = no effect).185 |
| Outputs (3) | |||
| BAND-PASS | audio | — | Band-pass filtered output; 6dB/oct (1-pole), passes frequencies around the cutoff and cuts both high and low extremes.185 |
| HIGH-PASS | audio | — | High-pass filtered output; 12dB/oct (2-pole), cuts frequencies below the cutoff frequency.185 |
| LOW-PASS | audio | — | Low-pass filtered output; 12dB/oct (2-pole), cuts frequencies above the cutoff frequency.185 |
Parameters 7
| Name | Type | Range | Behavior |
|---|---|---|---|
| Attenuator | knob | — | Controls the modulation depth of the Right CV input on cutoff frequency. Fully counter-clockwise yields zero modulation.185 |
| CHARACTER | switch | — | Two switches that change resonance response character. Both down = sinewave; upper switch on = edgy/sharp; lower switch on = sawtooth. May disrupt V/Oct tracking when activated. Also changes waveform when self-oscillating.185 |
| CUTOFF | knob | — | Sets the cutoff frequency. The total cutoff is the sum of this knob's value and the two CV inputs.185 |
| DRIVE | switch | — | Switch that changes the gain range of the Input level knob. OFF (lower): gain range 0–2. ON (upper): gain range 0–10, likely to overdrive the input.185 |
| Input level | knob | ≥0 | Sets the input signal gain. With Drive OFF: gain 0–2. With Drive ON: gain 0–10. Heavily affects filter response and interacts with Character switches.185 |
| RESONANCE | knob | — | Emphasises the cutoff frequency. At maximum (fully clockwise), the filter self-oscillates at the cutoff frequency, producing a 0°/90°/180° phased sinewave at LP/BP/HP outputs.185 |
| TRIMMER | knob | — | V/Oct calibration trimmer for adjusting the V/Oct tracking of the filter.185 |
