Synthesizers

Award-winning and versatile — for any sound

Heisenberg

Four-operator phase-modulation synthesizer with flexible modulation matrix and dynamic control. Perfect for digital pianos, bells, basses, and experimental textures.

Pulverisateur

Versatile virtual-analog synthesizer with three oscillators, dual filters, and full modulation. Ideal for classic subtractive synthesis, basslines, leads, and pads.

Space

Spectrum-based wavetable synthesizer with two blendable slots and stereo tools. Perfect for evolving pads, textures, and animated leads.

Bassline

Monophonic bass synthesizer inspired by the 303, with a built-in step sequencer. Create squelchy, resonant basslines with Accent, Slide, and Groove for classic acid grooves.

ToneMatrix

Visual step-sequencer and simple synthesizer. Click to place notes on a 16×16 grid, add groove, and route MIDI to other synths. Perfect for melodic patterns and experimental sequences.

Gakki

High-quality curated sound library with versatile character. Perfect for adding organic and natural instruments.

Drum Machines

From retro classics to modern percussion

Machiniste

Powerful drum machine with extensive sound design capabilities. Create everything from classic drum sounds to experimental percussion.

Beatbox9

Classic 9-channel drum machine inspired by the iconic 909. Build complex rhythms with professional-grade drum synthesis.

Beatbox8

Classic 8-channel drum machine inspired by the legendary 808. Perfect for creating tight, punchy rhythms with full control over each sound.

Effects

Shape and transform your sound

Quasar

Plate-like reverb effect. Create lush, evolving spaces with pre-delay, filtering, decay, and diffusion controls.

Pulsar

Stereo delay with per-channel pre-delay, filtering, and internal LFO modulation. Build large stereo spaces with rhythmic movement.

Rasselbock

Resampler with sequencer grid and seven built-in effects. Route through one master or separate per effect outs, reverse, pitch shift, and create experimental patterns.

Helmholtz

Comb filter with five tuneable resonant frequencies. Creates dramatic resonances, especially reactive to noise and impulsive inputs.

Gravity

Single-band compressor with visual feedback and gain reduction meter. Control threshold, ratio, knee, attack, and release with RMS or peak detection.

Quantum

Multi-band compressor designed for mastering. Four bands with adjustable crossovers, per-band bypass/mute/solo, and spectrum analyser.

Curve

6-band EQ with spectrum analyser. Boost or attenuate different parts of the spectrum.

Orbit

2-band EQ with spatial control of the stereo field.

AutoFilter

Dynamic filter driven by an envelope follower or sidechain input. Creates rhythmic movement and ducking effects automatically.

Exciter

Spectral enhancer that splits the signal into bands, applies distortion to higher frequencies, then recombines. Add presence and clarity to your tracks.

Panorama

Independent left/right pan and level controls for fixing imbalances and designing stereo movement.

Ring Modulator

Multiplies two signals to produce metallic or robotic timbres. Perfect for experimental textures and robotic sounds.

Stereo Enhancer

Widen the stereo field and enhance spatial perception in your mix or master output.

WaveShaper

Drawable transfer curve for designing distortion with precise control over harmonic content. Perfect for unique distortion shapes and extreme sound design.
