Features
11 Synthesis Engines
| Engine | Description |
|---|---|
| Subtractive | Hybrid anti-aliased oscillators (ADAA + BLEP) with ZDF filters |
| FM | Free 3x3 operator matrix, PM + true FM |
| Wavetable | Mip-mapped, ADAA, Hermite interpolation, in-app editor |
| Granular | Grain synthesis with real-time cloud visualizer and live capture |
| Spectral | FFT freeze/blur/shift/gate/morph with resynthesis |
| Physical Modeling | Karplus-Strong, bow, blow, strike |
| Phase Distortion | CZ-style synthesis |
| Formant | Vowel synthesis with morphable vocal targets |
| Sample | Single-cycle, multi-sample, loop playback |
| Neural (RAVE/DDSP) | Latent-space navigation with GPU inference (CUDA) |
| Genetic Breed | Evolutionary sound design via crossover and mutation |
Sound Architecture
- 64 voices with 16 unison per note, per-voice panning and analog drift
- 6 filter types: SVF, Moog Ladder, Comb, Formant, Phaser, Diode (ZDF topology, f64 precision)
- Modulation: 256-slot matrix, 32 audio-rate LFOs, 16 MSEGs, chaos modulators, 8 macros
- Effects: FDN reverb, convolution (GPU), delay, chorus, distortion, EQ, vocoder, stereo widener
- Arpeggiator with ratchet and probability, clip sequencer with parameter locks
- 8 scenes with morphing, N-preset morph space (Wasserstein optimal transport)
- Quality governor: Live / Studio / Render modes
Technology
- DSP: Zig 0.14.x — f32 pipeline, f64 ZDF filter integrators, SIMD vectorization, comptime LUTs
- UI: Svelte 5 (Runes) + Vite + TypeScript, WebKitGTK WebView, dark theme with neon accents
- Plugin: CLAP 1.2.7 with hand-written bindings, per-note modulation, thread-pool extension
- Audio: JACK (PipeWire), ALSA direct, multi-output (stereo + 8 aux)
- Threading: Lock-free work-stealing thread pool, dual-mode scheduling
Accessibility
- Native screenreader support (ARIA labels on all controls)
- Full keyboard navigation (Tab/Shift-Tab/Arrows/Enter)
- High-contrast and colorblind modes
- Scalable UI (125%/150%/200%)
