Est. MMXXVI — Four instruments in catalogue

Four synthesis
engines you can't
buy anywhere else.

Additive resurrected from the Kawai K5000. Vector morphing off the Yamaha TG-33. A phase-motion engine that exists nowhere else. And oscillators you build by typing a sentence. We make the instruments the industry skipped — and we make them deep.

The Catalogue

Four engines, four sounds.

No clones of the same five polysynths. Each title ships VST3 / CLAP / Standalone, runs offline, built on JUCE 8. Buy once, own it.

No. 01TR·SPK

Spektra-5000

The Kawai K5000, reborn in software

The first software recreation of the K5000 advanced additive synthesizer. 64 harmonics per source, six sources, spectral MORF morphing, a 128-band formant filter, all 37 original effects, and a librarian that reads real .KAA / .KA1 / .SYX banks.

TeeJee

The only TG-33 vector synth as a plugin

Four-waveform vector morphing on a responsive joystick, 2-op FM with anti-aliased oscillators, a band-limited wavetable engine, full MIDI, and a SysEx librarian that round-trips patches with real TG-33 hardware.

STRATA

Phase-motion synthesis — a genuinely new engine

Two DSP primitives nobody else has built: a per-partial modulation matrix, and phase-motion synthesis that swings crest factor while holding RMS invariant. 16-voice, MPE, unison, per-op spectral cutoff/resonance, 22 modulation destinations.

Triple Helix

Type a word. Get a sound.

A synthesizer with AI oscillators. Describe a sound in plain English and Triple Helix builds it — locally and offline via ACE-Step neural inference, or through the Claude API. 30,000+ lines of DSP, an 11-stage FX chain, a 32-slot mod matrix, 4 LFOs.

We build software synthesizers the industry hasn't gotten around to — and we build them properly, with the depth serious sound designers expect.

Not another reissue of the same five analog polysynths. The engines that got left behind: additive, vector, phase-motion, AI-generated.

Every instrument ships as VST3, CLAP and Standalone on Windows; macOS and Linux builds are planned. It works offline. There's no subscription and no cloud requirement — you buy it once and you own it. Each title carries its own about screen and developer credit, because real people wrote every line.
