Advanced Wavetable Polysynth

Fermenter

Flexible synthesis for everything from classic pads to modern textures. The heart of the Sourdaw ecosystem.

Stage 01 / Oscillation

Wavetable Synthesis

High-resolution oscillators meet deep wavetable architecture. Import custom waveforms or generate pristine analog primitives with clinical accuracy.

Interactive visualization ensures you see exactly how your sound is being shaped, giving you total control over the harmonic content of your signal.

Zero-Delay Filters

Modeled filter topologies provide everything from smooth ladder-style response to aggressive, screaming resonance.

Switch instantaneously between Clean, Moog ladder emulations, and high-resonance Acid models for surgical frequency control.

Stage 03 / Kinetic Motion

Advanced Modulation

Lifeless synthesis is a crime, so we gave you a deep modulation matrix with multiple LFOs and envelopes.

Visually plot Amp and Filter ADSR parameters, then map any LFO out to any internal target for complex, evolving textures.

Integrated FX Chain

Professional instruments deserve professional processing. Fermenter features an integrated suite of studio-grade effects.

Ships out of the box with custom-tuned Distortion, wide-plate Reverbs, and ensemble choruses for final polish.

Visual Routing

A clear, interactive graph of your signal path. Trace your sound from the oscillators through the warp engines to the final output.

Tracing starts from the active layers and visually connects through Warp engines. Active modules are highlighted with their respective color codes, giving you instant situational awareness of your signal flow.

Stage 06 / Morphing

Macro Morphing

Route multiple parameters to a single macro node for expressive performance. Interpolate between different sonic states with a single movement.

Interpolate seamlessly between starkly different sonic states—blend a raw analog Saw with a granular Vocal texture just by dragging a node. Build kinetic movement into your patches effortlessly.
