4NTHRACITE

Industrial Kick Engine

Precision kick drum synthesizer with layered transient, noise, and saturation stages — driven by a 16-step pattern sequencer.

Euclidean Rhythm Generator

6-track polymetric drum machine that distributes hits evenly using the Euclidean algorithm, creating evolving polyrhythmic grooves.

Non-Linear Drum Sequencer

6-channel drum sequencer where a hand-drawn tempo curve controls how fast or slow each individual step plays.

Cellular Automata Sequencer

8-track drum sequencer driven by Langton's lambda cellular automaton — patterns evolve continuously based on a CHAOS knob.

Polymetric Beats

6-channel step sequencer where each channel runs at its own independent step count, producing natural polyrhythmic phase drift.

Snake Sequencer

Steer a snake across a sound grid with arrow keys. The trail it records plays back as a looping sequence with lo-fi bit-crush.

Ball Physics Sequencer

Bouncing balls trigger musical events on collision. Adjust gravity and damping to shape the rhythm's energy and density.

Kinetic Audio Physics Engine

2D physics sandbox where ball emitters bounce off walls and user-placed objects, generating non-repeating collision-based rhythms.

Turing 303

TB-303 style acid synthesizer driven by a 16-bit Turing machine shift register — from locked patterns to maximum chaos.

Pendulum Drone

Drone synthesizer whose timbre is modulated by a simulated multi-arm pendulum. Drag the bob; add motors for infinite oscillation.

Equal Division Arp Synth

Synthesizer tunable to any equal division of the octave — 5-EDO to 31-EDO and beyond — with a dynamically redrawn keyboard.

Fusion Architect

4-operator FM synthesizer driven by a stochastic chord navigation puck moving through a 2D harmonic tension space.

Topology Sequencer

Spatial sequencer on a 35×37 deformable mesh. Smudge the grid in real time to reshape the melodic contour of each column.

Paint Synth

Canvas synthesizer where painting directly produces sound. Vertical axis = frequency; a scanning playhead reads your brushstrokes.

Neural Topology Synth

Loads audio and extracts 8 spectral engrams distributed across a neural network. Mouse blends engrams across 40 oscillator voices.

Geometric Harmony Sequencer

Timeline canvas where placed chord blocks trigger polyphonic harmonies under a sweeping playhead. Just-intonation snap available.

Tonnetz Grid

Interactive Neo-Riemannian hexagonal lattice where adjacent nodes form triads. Click to record a path for melodic voice-leading playback.

Harmonic Mandala

Generative chord explorer displayed as nested harmonic rings. Hover to hear; click to record a looping sequence with Coltrane-style changes.

Stochastic Fusion Groove Architect

Stochastic groove generator simulating guitar, violin, and saxophone improvising over randomised chord progressions.

Maqam Step Sequencer

Step sequencer tuned to Arabic maqam scales with authentic quarter-tone microtonal intonation — rendered without rounding to 12-TET.

Edge of Chaos

Generative sequencer driven by a 5-neighbourhood cellular automaton. A roaming probe cursor collects live cells and triggers their pitches.

Granular Synth

Classic granular synthesis engine. Load any audio file; control grain size, density, drift, and direction for infinite textural variation.

Matrix Granular

Granular synthesizer built around a painted grid matrix. Paint cells to arm grain-trigger positions; a playhead fires them from your sample.

Live Loop Recorder

5-channel live looper with per-channel trim markers, SYNC mode, and a 16-step sequencer for triggering loops in time.

Shoegaze Processor

Live audio processor with granular pitch shift, feedback delay network reverb, and shimmer. HOLD freezes the wet tail indefinitely.

Spectral Editor

Partial-based additive synthesizer with a visual FFT editor. Drag, add, or delete sinusoidal partials; hear resynthesis in real time.
