Ripples
Visualization filter_response
Capabilities 2
- Voltage-Controlled Amplifiervca
- Internal VCA on the LP4>VCA output, controlled by the GAIN CV input (0V = silence, 5V = unity gain).249
- Voltage-Controlled Filtervoltage-controlled-filter
- Multimode VCF with BP2, LP2, LP4 outputs and integrated VCA on LP4; self-oscillates as a sine oscillator at maximum resonance.249
Jacks 9 — 5 in / 4 out
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (5) | |||
| FM | cv | — | Cutoff frequency CV input, attenuated and polarized by the FM attenuverter knob.249 |
| FREQ | cv | — | 1 V/Oct cutoff frequency CV input, calibrated for keyboard tracking. At maximum resonance with no input, Ripples self-oscillates as a sine wave oscillator.249 |
| GAIN | cv | ≥0V | VCA control voltage for the LP4>VCA output. 0V silences the signal; 5V applies unity gain. Values above +5V are progressively compressed.249 |
| IN | audio | — | Audio signal input. DC-coupled at the input; the internal connection to the VCA stage is AC-coupled.249 |
| RES | cv | — | Resonance CV input, added to the RES knob setting. +4V starts self-oscillation; voltages above +5V are non-linearly compressed.249 |
| Outputs (4) | |||
| BP2 | audio | — | 2-pole band-pass filter output.249 |
| LP2 | audio | — | 2-pole low-pass filter output.249 |
| LP4 | audio | — | 4-pole low-pass filter output. At maximum resonance with no input, produces a clean sine wave during self-oscillation.249 |
| LP4>VCA | audio | — | 4-pole low-pass output processed by an internal VCA, controlled by the GAIN CV input. The ideal end-of-chain output for subtractive synthesis.249 |
Parameters 3
| Name | Type | Range | Behavior |
|---|---|---|---|
| FM | knob | — | Attenuverter that adjusts the amount and polarity of frequency modulation from the FM input.249 |
| FREQ | knob | 18Hz – 18000Hz | 249 |
| RES | knob | — | Controls resonance level. Self-oscillation occurs at about 80% of the course of this potentiometer.249 |
