Resynthesis drum machine

Every drum, synthesized.

Drop in any hit - a kick, a snare, a conga - and Rhythmica rebuilds it as its own synth patch instead of playing the sample back. Every layer stays editable, and a step sequencer plays the kit.

The Rhythmica editor: a 909 kit on the step grid, with an Osc kick, a Partials ride, a Particles shaker and an Analog conga page around it

Resynthesis

Drop in a hit. Get back a patch.

Samples are frozen. A synth patch moves: retune it, shorten it, push its drive, and it still sounds like itself. Rhythmica measures a recording and writes the layers that make it.

Drop a recording

A one-shot from your library, or a slice cut from a break. Press Resynthesize and pick the sound it lands on.
It is measured, not guessed

The body's pitch sweep and level are read off the hit; the click and the ring become phase-locked partials. No model in the loop.
Edit what came out

The result is plain layers - an Osc, a Partials bank, curves you can drag - in the same editor as everything else.

Sources

Eight ways to make a sound.

Each zone is a stack of layers, each layer one source with its own FX chain. A kick is not a special mode - it is a layout you can take apart.

Osc page: a kick's pitch and amp curves over its waveform

Osc

Basic shapes or band-limited harmonic tables, written by hand or by formula. Pitch, amp and drive move on curves you draw.

pitch 1.2 kHz -> 48 Hz / drive curve / formula tables

Play the Osc preview

Partials

A bank of sine lines, each with its own pitch, level and decay. Cymbals, rings and clicks rebuilt line by line.

128 phase-coherent lines / per-line decay / formula mode

Play the Partials preview

Particles

Hundreds of tiny impacts shaped by a density curve and a material. Shakers, claps, sizzle.

761 hits / density 700 / seeds, metal, hands

Play the Particles preview

Struck

Physically informed: an exciter - impulse, noise, impact or particles - driving up to three modal bodies.

exciter + 3 bodies / hardness / damping

Play the Struck preview

Analog

Circuit-level ports of classic drum machine voices: pinged resonators, gated VCOs, filter pings.

909 / 808 voice ports / tune, decay, tone

Play the Analog preview

NoiseColoured noise through its own filter and curves. Snare wires, air, tails.Play the Noise preview
MetalStacked square oscillators beating against each other - the 808 hat, and everything past it.Play the Metal preview
SamplerWhen a recording is the right answer: slices with start and end, under the same FX and modulation.

Sequencer

A drum machine, not just a synth.

Every zone gets a lane, level with its row in the kit. Program a groove, lock any parameter to a step, and chain patterns into a song.

The step grid: a 909 techno pattern across nine zones

P-locksAny parameter, set per step.
ChanceProbability and ratchets on every step.
GrooveSwing, rate from 1/4 to 1/32, and a time bend across the bar.
PatternsSixteen per kit, chained, synced to the host.
ZonesUp to sixteen, with choke groups and a key each.
MacrosEight per zone and eight for the kit, all host-automatable.

Specs

Under the hood.

Formats: VST3, AU, CLAP, LV2, Standalone

Kit: 16 zones, each a stack of layers + FX

Modulation: Matrix: macros, velocity, curves, MIDI CC, pressure, bend, key, random

Render: Deterministic: a patch plays back bit-identical, every time

FX: Per-layer and master chains, multiband splits

Export: The selected zone as WAV, the sequence as MIDI

History: Undo / redo across the whole kit

Presets: Kits with their patterns, samples embedded
