Module reference

All 99 modules, one line each — the same descriptions the app shows in its add menu and quick-add palette. This page is generated from the module registry in the source code, so it always matches the build it documents.

Oscillator

Anti-aliased oscillator: sine/triangle/saw/square with pitch and FM inputs.

FM Osc

Two-operator FM (DX-style), 4x oversampled so high-index sidebands stay clean; ratio and index take CV.

Supersaw

Seven detuned saws (JP-8000 style) for huge unison leads and pads; detune and mix take CV.

PWM Osc

Variable-width pulse oscillator with a PWM input - an LFO here gives the classic moving-pulse sound.

Wavetable

Scans a bank of eight band-limited waveforms by Position + CV (PPG/Plaits lineage); mip-mapped tables stay alias-free up the keyboard.

Poly Synth

Self-contained 8-voice subtractive synth - play MIDI/QWERTY chords; osc into envelope-modulated filter, with cutoff/res/level CV.

Resonator

Karplus-Strong plucked string: trigger for plucks or feed audio to excite it; tuned by pitch CV.

Sampler

Record/playback looper: captures its audio input while Rec is high, then plays it back varispeed (Pitch CV) on Trig or loops; start point and level take CV.

Noise

White and pink noise with level CV - a source for percussion, wind, and sample & hold.

Chiptune

NES-style sound chip: fixed-duty pulses, bit-stepped triangle and LFSR noise; Gate hard-mutes like the real hardware. Proudly aliased.

Granular

Record up to 10s (Rec gate), then scatter it as a grain cloud: Position scrubs, Size/Density set the fabric, Spray blurs, Pitch transposes per grain.

Kick

Analog kick drum: swept sine with click and drive, switchable 808/909 character. Trigger to play.

Snare

Snare: tuned shell partials plus noise 'snappy'; Snappy balances body against the wires.

Hi-Hat

Metallic six-oscillator hat with separate closed (Trig) and open inputs; a closed hit chokes the open tail.

Clap

Hand clap: band-passed noise through the classic multi-pulse 'many hands' envelope.

Tom

Tom/drum: swept sine with skin noise; pitch CV turns one module into a melodic tom row.

Cowbell

808 cowbell: two detuned squares through a resonant band-pass.

Clave

Clave/rimshot: a short damped sine ping with an inharmonic partial.

Rimshot

808-style side-stick crack: two detuned clicks plus a noise snap, hard-clipped.

Ride

Ride cymbal: metallic cluster split into a bell 'ping' and high sizzle with a long tail.

Crash

Crash cymbal: metal cluster drowned in noise wash with a hard strike and a long, dark tail.

Formant

Vowel filter: three formant band-passes morphing A-E-I-O-U via the Vowel knob/CV. Talk-box and choral tones.

Lowpass Gate

Buchla-style low-pass gate: a vactrol opens filter and amp together for organic plucks. Ping to strike.

Amp

Amplifier (VCA): an envelope or LFO into CV shapes the level per note. With nothing in CV it simply passes at the Gain knob - it won't gate on its own.

Mixer

Four-channel mixer with per-channel level - sums audio or CV.

Crossfade

Morphs between A and B by knob + CV, linear or equal-power; works on audio or CV.

Pan

Equal-power panner: places a mono signal across L/R, with CV for auto-pan.

Attack-decay-sustain-release envelope, triggered by a gate; all four stages take CV. Patch into a VCA or filter CV.

Function

Maths-style rise/fall slope: an envelope when triggered, an LFO when cycling, with an End-of-Cycle trigger out. Rise/fall/curve/level all take CV.

Coin-toss gate: routes each trigger to A or B by probability - living, varying rhythms.

Logic

Gate logic (AND/OR/XOR/NOT): combine two clocks or gates into new rhythms.

Sample & Hold

Grabs the input voltage on each trigger and holds it (normalled to noise for random stepped CV).

Random

Clocked randomness: a probability gate, a fresh S&H voltage, and a bounded random walk. Prob and Step take CV.

MSEG

Draw your own envelope: up to 16 breakpoints in the on-module editor, looping free or tempo-synced, or one-shot from Trig. EOC out for chaining.

Chaos

Chaotic LFO: Lorenz attractor swoops, logistic-map staircases or a drunken walk - never repeats, always related. Slew rounds the edges; rate/chaos/slew take CV.

Sequencer

Seq 16

16-step CV/gate sequencer with forward/reverse/ping-pong/random playback directions.

Gate Seq

8-step probability trigger sequencer: each step fires with its own chance - grooves with controlled chaos.

Euclid

Euclidean rhythm: spreads Fills evenly across Steps, with rotation; Fills/Rotate take CV. Cycle out for chaining.

Turing

Looping random sequencer: Change morphs from a locked repeating CV loop to fully random; clocked.

Clock

Master clock with BPM and multiplier; Sync mode locks to the global transport so clocks start together.

Clock Div

Divides a clock by 2/3/4/5/7/8 simultaneously, with reset - the source of polyrhythms.

Clock Scale

Multiplies/divides an incoming clock (incl. x1.5, x2.5) staying phase-locked - dotted and triplet feels.

Swing Clock

Clock with shuffle: every second pulse lands late by the Swing amount - straight 16ths become a groove. Free or transport-synced.

Burst

One trigger in, a ratchet of 1-8 pulses out; Curve rushes or trails the spacing. Rolls, flams and stutters.

Shift Reg

Analogue shift register: each clock pushes the sampled CV down four outputs - melodies become canons. Input normalled to noise.

Arpeggiator

Hold a chord, get a pattern: up/down/up-down/played/random across 1-4 octaves, stepping on the transport or an external clock. Outputs pitch/gate/vel CV.

Piano Roll

Draw a looping clip (chords welcome) in the piano-roll editor; plays in sync with the transport. Voice 1 outputs pitch/gate/velocity; chords spread across four voices (V2-V4 pitch+gate).

Attenuverter

Dual scale + offset for CV: attenuate, invert, or add a constant; unpatched it's a manual CV source.

Slew

Slew limiter / glide: smooths CV with separate rise and fall; pitch CV here gives portamento.

Quantizer

Snaps pitch CV to a musical scale (major/minor/pentatonic...) in any key - turns random voltages into melody.

Octave

Transposes pitch CV by octaves/semitones and warps the volt-per-octave slope (microtonal).

Env Follow

Extracts an amplitude envelope (and a gate) from any audio - for audio-reactive modulation.

Comparator

Outputs a gate when a CV crosses a threshold (with hysteresis) - derive rhythm from an LFO.

Macro

One Macro knob drives four CV outputs, each at its own bipolar depth - move many parameters with one gesture.

XY Pad

Draggable 2D controller with X and Y CV outputs (uni- or bipolar) - hands-on two-parameter morphing.

Switch

Sequential switch: a trigger steps the output between inputs (forward/pendulum/random). Route chords or sources on the fly.

Scope

Inline oscilloscope: visualises a passing signal with a zero-crossing trigger; doesn't alter it.

Meter

Stereo peak/RMS level meter with peak-hold; passes audio through. Park it before the Output.

CV Math

Two attenuverted inputs combined four ways at once: Sum, Mult, Min and Max outputs. Modulation glue.

Track & Hold

Follows the input while the gate is high, freezes otherwise - Sample & Hold's smoother sibling.

Notes

A sticky-note for the canvas: type anything, it saves with the patch. Annotate your patching for future-you.

Spectrum

Log-frequency spectrum analyser: passes audio through while drawing 20 Hz-Nyquist bars with dB scaling. Park it anywhere in a chain.

Wavefolder

West-coast wavefolder: folds peaks back for added harmonics; fold depth and symmetry take CV. Best on sines.

Bitcrush

Lo-fi: bit-depth reduction plus sample-rate decimation, both CV-controllable.

Ring Mod

Ring modulator: multiplies the input by an internal (1V/oct) or external carrier for metallic tones.

Reverb

Six spaces in one: Classic, Small Room, Chamber, Hall, Cavern and Blackhole (near-infinite). Size sets decay; size/damp/mix all take CV.

Flanger

Swept short delay with feedback - from subtle comb shimmer to full jet engine. Rate/Depth/Mix CV.

Pitch Shift

Dual-tap delay pitch shifter, +/-12 semitones; Shift CV in octaves - an LFO warbles, a sequencer harmonises.

Looper

Gate-driven live looper: Rec sets the loop (up to 30s), Dub layers sound-on-sound with Decay, Clear wipes. Drive it from gates for hands-free looping.

Shimmer

Reverb with a pitch shifter inside the feedback loop - tails climb by Shift semitones every pass. Freeze locks an infinite, still-rising pad.

Vocoder

12-band channel vocoder: a voice into Mod In shapes the carrier (internal saw with Pitch CV, or patch your own). Shift bends formants; Sibilance keeps consonants crisp.
