Architecture

Instrument architecture

A production-grade wavetable synthesizer — not a preset player. Every layer is addressable.

WavetableBank

256 frames × 2048 samples with linear and spectral crossfade between positions.

Voice engine

Multi-oscillator wavetable synthesis, ADSR, state-variable filter, and modulation routing.

Import & export

Vital .vitaltable, Serum .fxp, WAV cycles, Ableton param JSON, SFZ, MIDI, and reelpack/ bundles.

.reelwt .reelpreset reelpack/

Offline rendering for pipelines

PyO3 bindings let Studio render notes headlessly — import a table, route modulation, export stems without opening a UI.
