Mangrove

Whimsical Raps (Mannequins)

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)

NameSignalVoltageDescription
Inputs (6)
AIR InputcvCV input for the VCA/overdrive/wavefolding circuit; accepts envelopes or audio-rate signals for AM and harmonic content control.906
FM INDEX InputcvCV input for the FM depth multiplier; unpatched gives 100% modulation, positive voltages increase depth, negative voltages invert it.906
FM InputaudioLinear through-zero FM input from another audio source; depth is scaled by FM INDEX.906
PPM TRIGGER InputmixedPPM expander jack; accepts audio or clock signals to override the SINE-to-TRIGGER normal and drive the IMPULSE oscillator externally.906
SYNC InputtriggerHard-sync input that resets the oscillator cycle on each trigger.906
V/8 InputcvStandard 1V/octave pitch CV input controlling the oscillator's fundamental frequency.906
Outputs (5)
FORMANT OutputaudioSpectrally shaped wave-impulse output driven by all MANGROVE settings; the primary audio output.906
PPM PWM Outputaudio906
PPM SAW Outputaudio906
PPM SINE Outputaudio906
SQUARE OutputaudioRaw square wave output affected only by pitch and FM; useful as a stable modulation or sync source.906

Parameters 7

NameTypeRangeBehavior
AIRknobControls 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
BARRELknobControls 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
Zones
Sawtooth
Triangular
Ramp
  • Sawtooth -100–0%Counter-clockwise from noon makes the wave-impulse sawtoothed in character.906
  • Triangular 0–0%At noon (12 o'clock) the waveform is triangular.906
  • Ramp 0–100%Clockwise from noon introduces even harmonics, transitioning toward a ramp waveform with increasing intensity.906
CONSTANT SwitchswitchSelects between constant wave and constant formant operating modes, fundamentally changing how FORMANT and BARREL interact and how pitch division/melody folding behaves.906
FINEknobFine frequency control extending pitch range by one additional octave.906
FORMANTknobSets the formant frequency, shifting the resonant spectral peak from contrabass through soprano; interacts with BARREL to define the harmonic impulse shape.906
PITCHknobSets the oscillator's fundamental frequency with coarse control; an additional FINE knob extends the range by one octave.906
PPM Mode SwitchswitchThree-position switch on the PPM expander selecting impulse, sync, or cycle behaviour for the IMPULSE oscillator relative to the CORE.906
