The only TG33 vector synthesizer as a plugin. Four-waveform vector morphing via a responsive joystick, 2-op FM with anti-aliased oscillators, a band-limited wavetable engine, and a full SysEx librarian for the real hardware.
Drag the joystick · A:50% B:50% C:50% D:50%
The Yamaha TG-33 had a joystick. Push it around, and four sound sources — A, B, C, D — morphed and blended in real time. FM could dissolve into wavetable, pulse could bleed into saw. It was expressive, intuitive, and nobody turned it into a plugin. Until now.
TeeJee faithfully recreates the TG-33's vector engine and extends it with modern sound quality, a built-in effects rack, and round-trip SysEx transfer with the original hardware.
Four independent sound sources (FM, saw, pulse, wavetable) blend via a responsive on-screen joystick with 50-step level and detune sequences. Real-time morphing that no subtractive filter can replicate.
Two-operator FM synthesis with oversampled oscillators achieving −48 dB aliasing. Clean, precise FM that the original 12-bit hardware couldn't deliver.
A band-limited AWM wavetable engine provides alias-free waveforms across the entire keyboard range. Verified alias-free at all frequencies through automated testing.
Transfer patches between TeeJee and the real TG-33 hardware via SysEx. The codec is tested 18/18 — every parameter round-trips correctly. Import, organize, audition, and export banks.
A 16-slot effects chain with drive, EQ, modulation, delay, and reverb modules. Build your own signal flow per patch or use the factory effect presets.
52 carefully curated factory presets spanning ambient pads, gritty leads, deep basses, percussive keys, evolving textures, and organ variations. Each showcases the vector engine's range. Plus a built-in random patch generator.
