Mangrove
Mannequins formant oscillator: a single-oscillator voice whose FORMANT control sweeps a movable spectral peak independent of pitch, with AIR (breath/noise) and BARREL (timbre/body) shaping. Ships with the bundled 2HP PPM expander exposing Impulse/Cycle/Sync behaviours for patch- programmable formant work.906
Capabilities 3
- FM Oscillatorfm-oscillator
- FM INPUT provides linear through-zero frequency modulation with CV-controllable depth via FM INDEX.906
- Formant Oscillatorformant-oscillator
- Mangrove shapes spectral peaks via FORMANT and harmonic density via BARREL, clocking an impulse at the given PITCH, with a VCA/overdrive on AIR and linear through-zero FM.906
- Voltage-Controlled Amplifiervca
- The AIR circuit integrates a VCA with overdrive and subtle wavefolding, controllable via CV through an attenuverter.906
Jacks 11 (6 in / 5 out)
| Name | Signal | Voltage | Description |
|---|---|---|---|
| Inputs (6) | |||
| AIR Input | cv | — | CV input for the VCA/overdrive/wavefolding circuit; accepts envelopes or audio-rate signals for AM and harmonic content control.906 |
| FM INDEX Input | cv | — | CV input for the FM depth multiplier; unpatched gives 100% modulation, positive voltages increase depth, negative voltages invert it.906 |
| FM Input | audio | — | Linear through-zero FM input from another audio source; depth is scaled by FM INDEX.906 |
| PPM TRIGGER Input | mixed | — | PPM expander jack; accepts audio or clock signals to override the SINE-to-TRIGGER normal and drive the IMPULSE oscillator externally.906 |
| SYNC Input | trigger | — | Hard-sync input that resets the oscillator cycle on each trigger.906 |
| V/8 Input | cv | — | Standard 1V/octave pitch CV input controlling the oscillator's fundamental frequency.906 |
| Outputs (5) | |||
| FORMANT Output | audio | — | Spectrally shaped wave-impulse output driven by all MANGROVE settings; the primary audio output.906 |
| PPM PWM Output | audio | — | 906 |
| PPM SAW Output | audio | — | 906 |
| PPM SINE Output | audio | — | 906 |
| SQUARE Output | audio | — | Raw square wave output affected only by pitch and FM; useful as a stable modulation or sync source.906 |
Parameters 7
| Name | Type | Range | Behavior |
|---|---|---|---|
| AIR | knob | — | Controls the VCA gain; increasing it raises output volume then drives the overdrive/wavefolding circuit to add odd-harmonic overtones. Has an attenuverter for external CV control.906 |
| BARREL | knob | — | Controls harmonic density and timbral weight; at noon produces triangular shapes, clockwise fills in even harmonics toward a ramp, counter-clockwise produces a sawtooth-like wave-impulse.906 |
| CONSTANT Switch | switch | — | Selects between constant wave and constant formant operating modes, fundamentally changing how FORMANT and BARREL interact and how pitch division/melody folding behaves.906 |
| FINE | knob | — | Fine frequency control extending pitch range by one additional octave.906 |
| FORMANT | knob | — | Sets the formant frequency, shifting the resonant spectral peak from contrabass through soprano; interacts with BARREL to define the harmonic impulse shape.906 |
| PITCH | knob | — | Sets the oscillator's fundamental frequency with coarse control; an additional FINE knob extends the range by one octave.906 |
| PPM Mode Switch | switch | — | Three-position switch on the PPM expander selecting impulse, sync, or cycle behaviour for the IMPULSE oscillator relative to the CORE.906 |
