What PolyRex does
The instrument takes its starting point from analog polysynths of the early years of the form that the developer admires, keeping the glowing chorus, drifting movement and a soft but punchy filter.
Key features
- Vintage polysynth voicing. The core sound draws on classic polyphonic synthesizers, with a chorus-driven, drifting character and a filter that is soft but punchy.
- Modern reworking. The vintage voice is processed through the developer’s own colorful approach, so the sound is pushed further than a straight recreation.
- Warped and textured sounds. The sound set reaches from unstable tape-style keys to glassy plucks and warped chords, as well as pads and basses.
