A new instrument from the void.
A new shape to sound.
It's a deeply configurable audiovisual instrument with unique sound design and dazzling, meaningful visuals.
Specifically, Hyphasia is an infinitely polyphonic, polytimbral, microtonal synthesizer built around phase sculpture synthesis. The audio engine is paired with a real-time rendering of the synthesis internals.
In short: the particles are the instrument.
PSS builds sound from scratch, exciting the spectrum to create a phase-coherent, loop-stable waveform. Resynthesizing the waveform many times a second enables rich modulation and stage-ready response.
A good metaphor is to imagine a phonograph. The record spins, but the tone arm stays in the same spot, playing back whatever's under it. Phase sculpture synthesis works by constantly swapping out the record with a new one, created fresh from the performer's input.
Hyphasia is in active development and ready to play on Windows, but changing rapidly at this time. Linux builds will be coming soon, followed by Apple.
If you've got a project or a performance that depends on a certain Hyphasia sound, back up the executable or plugin along with the state as the instrument's sound will change.
Hyphasia is a GPU-native synth. It requires a graphics card with Vulkan 1.3 support and at least 2 GiB of VRAM. Additional instances may require additional VRAM. Older or integrated GPUs may be limited.
On Apple platforms, Apple Silicon (M1 or later) is required.
Hyphasia supports 16-channel MIDI and dual-zone MIDI MPE with per-note expression.
Field notes⧉ and clips are mainly on Bluesky.
Hyphasia is available DRM-free on itch.io.
