The instruments

A precision kick drum synthesizer built around layered synthesis stages. The core generates a pitched transient from a tunable oscillator with pitch envelope; the transient & noise layer adds attack click and body noise; the destruction & rumble stage applies saturation and low-end resonance for industrial weight.

A 16-step pattern sequencer with accent and reverse modes controls when the engine fires.

A 6-track polymetric drum machine that distributes hits evenly across steps using the Euclidean (Bjorklund) algorithm. Each track shows its pattern as a necklace of dots around a circle — active hits glow in the track colour, the current step is highlighted with a clockhand needle.

Each track has its own step count (K), so tracks naturally loop at different lengths, creating evolving polymetric grooves. Each hit triggers a synthesised drum voice with carrier oscillator, FM modulator, AM modulator, noise layer, wavefold distortion, and resonator. Sample override per track.

A 6-channel drum sequencer where a drawn tempo curve controls how fast or slow each individual step plays. The curve runs FAST (top) to SLOW (bottom) and is drawn directly on a canvas above the step grid.

The BAL button calculates timing deficit from drawn changes and randomly compensates by speeding up untouched steps — keeping the total loop length equal to the global BPM.

An 8-track drum sequencer driven by Langton's lambda cellular automaton rule. Each of the 16 cells holds a state 0–7 mapping to a rhythmic subdivision: 0=silent, 1=single hit, up through triplets, quadruplets, and 32nd-note bursts.

The CHAOS knob sets lambda — how ordered or random the CA's evolution is. Patterns mutate every N loops; any track can be frozen. Click cells to manually set states.

A 6-channel step sequencer where each channel runs at its own independent step count (4–32), naturally producing polyrhythmic phase drift. A 7-step channel against a 5-step channel creates a 35-step composite before repeating.

Per-step pitch nudge, just-intonation snap, and swing control allow fine timing and harmonic shaping of each channel.

An arcade-style sequencer where you steer a snake across a grid with arrow keys. The grid is seeded with coloured cells mapped to 4 synth slots. As the snake consumes cells it records a sequence of sound events; Play loops back through the recorded trail.

Bit-crush and sample-rate reduction quantizer for lo-fi textures. Pattern generator seeds the grid with interesting initial configurations.

A physics-based sequencer where bouncing balls represent musical events. Each ball has a pitch and synth voice; wall and ball collisions trigger notes. Adjust gravity and damping to change how long the bounce energy sustains.

A 2D physics sandbox where emitters launch streams of balls that bounce off walls and user-placed objects. Every collision triggers a sound event whose pitch and timbre is determined by the emitter preset and collision geometry.

Non-repeating rhythms emerge from simple initial conditions — the same setup never plays identically twice.

A TB-303 style acid synthesizer driven by a 16-bit Turing machine shift register. At 0% probability the register loops identically (stable pattern); at 50% it randomly flips bits (maximum chaos); at 100% it mirror-flips.

Click the LED bit-row to write pitch values directly. Features sawtooth or square waveforms, resonant 303-style low-pass filter with envelope modulation, portamento, accent, and reverb.

A drone synthesizer whose timbre is controlled by a simulated multi-arm pendulum. Each arm's angular position modulates an audio parameter (filter cutoff or wavefolder drive). Drag the bob to set it in motion; hold to dampen.

Arms can be equipped with motors to sustain oscillation indefinitely, creating self-modulating evolving drones.

A synthesizer tunable to any equal division of the octave (EDO) — from 5-EDO to 31-EDO and beyond. The keyboard dynamically redraws for the selected EDO, accurately rendering microtonal pitches.

Notes can be played as arpeggio (up / down / up-down / chord / random) or programmed in a 303-style step sequencer.

A 4-operator FM synthesizer driven by a stochastic chord navigation engine. A puck moves through a 2D tension space selecting chord targets that feed pitch into the FM operators. Selectable FM algorithms; operator 4 has self-feedback.

SCATTER mode maximises harmonic unpredictability, pushing the puck to distant chord targets and creating dissonant, evolving FM textures.

A spatial sequencer on a 35×37 deformable mesh grid. Rows = MIDI pitch; columns = time slices. A smudge brush distorts the mesh in real time; the sequencer reads pitch from a selected column — deformation above/below rest maps to semitone pitch shifts.

Moving between columns changes the melodic contour entirely, allowing you to sculpt a landscape of different melodies and navigate between them.

A canvas synthesizer where painting directly produces sound. Vertical axis = frequency; horizontal axis = time. A scanning playhead converts painted pixels to amplitude at the corresponding frequency.

Draw melodies as strokes or create rich spectral textures through layered colour. Different brush colours map to different timbres.

Loads an audio sample and extracts 8 spectral "engrams" — FFT frequency snapshots from evenly-spaced moments. These are distributed across a visual neural network of hundreds of nodes.

Moving the mouse probe blends nearby engrams in real time, driving 40 simultaneous oscillator voices. The entire timbral space is defined by your source audio.

A timeline canvas where chord blocks are placed by clicking. A block's horizontal position and width sets start time and duration; vertical position and height sets pitch range. A playhead sweeps left to right triggering polyphonic chords.

Double-click to add a block, drag to move, resize from edges. Just-intonation snap aligns pitches to pure harmonic ratios.

An interactive Neo-Riemannian Tonnetz — a hexagonal lattice where pitch classes are arranged so harmonically close notes sit physically close. Right = perfect fifth; diagonal = major/minor third. Any triangle of adjacent nodes forms a triad.

Hover to preview pitches; click nodes to record a path that plays back as melody or voice-leading.

A generative chord explorer displayed as nested rings radiating from a central root. Each ring expands outward by applying harmonic rules (perfect intervals, Coltrane changes, Zappa extensions) to the previous ring's chords.

Hover to hear; click to record into a looping sequence. Playback direction: forward, backward, or ping-pong.

A stochastic groove generator simulating a small fusion ensemble. A chord progression displayed as blocks is randomisable. Three voices — guitar, violin, saxophone — each generate idiomatic phrasing over the changes.

A live-play mode lets you improvise alongside the generated ensemble. Per-instrument volume control.

A step sequencer tuned to Arabic maqam scales with authentic microtonal intonation. Maqams include Nahawand, Hijaz, Bayati, Rast, and others. The pitch rows update to reflect each maqam's specific interval ratios including quarter-tone steps.

Notes placed with 0.5-step resolution; rendered accurately without rounding to 12-TET.

A generative sequencer driven by a 5-neighbourhood cellular automaton where each live cell corresponds to a scale degree. A circular probe cursor collects cells inside it each beat and triggers their pitches. The CA evolves continuously.

Up to 12 scale degree slots; scan modes: random, left-to-right, top-to-bottom. Sample override per slot.

A classic granular synthesis engine. Load any audio file; a read-position pointer moves through the sample. The engine continuously fires small grains; SIZE, DENSITY, and envelope shape determine texture.

DRIFT causes the read position to wander. Grains can play forward, reverse, or alternating. Pitch transposition is independent of playback speed.

A granular synthesizer built around a scrollable grid matrix. Horizontal = time, vertical = pitch offset. Paint cells to arm grain-trigger positions; a moving playhead fires grains at armed cells from a loaded audio sample.

SCATTER randomises read position for cloud-like texture. Transient detection intelligently maps sample regions to the pitch axis.

A 5-channel live looper with integrated step sequencer. Each channel records from any audio input and plays back as a continuous loop. Channel 1 is master; SYNC auto-stops recording on channels 2–5 at the master loop length.

Each channel has a waveform display with draggable start/end trim markers (down to 5ms). A 16-step sequencer at the bottom triggers any channel per step, synced to global BPM.

A live audio processor for lush, cascading ambience. Processes mic or file input through three stages: granular pitch shifter (harmonic colour), feedback delay network (dense diffuse reverb), and shimmer (pitch-shifts reverb up an octave and feeds it back into the FDN).

HOLD freezes the current wet tail indefinitely, sustaining infinite reverb pads.

A partial-based additive synthesizer with a visual editor. Load audio to extract sinusoidal components via FFT partial tracking — each partial appears as a dot on the frequency/amplitude canvas.

Drag partials to change frequency or amplitude; draw new ones from scratch; delete existing ones. Playback resynthesizes the current partial set in real time.
