Khorlo is a free experimental synth from JAS-I built around eight physically modelled strings struck by eight independent impulse pluckers that rotate around a 3D cylinder. Instead of the usual oscillators and envelopes, the sound and rhythm come from how the pluckers hit the strings, so it works as a self-generating rhythm engine as much as a synth.
Features
- Eight independent strings and pluckers, each rotating at its own speed, for overlapping polyrhythms and evolving patterns.
- Pluck height changes the tone in real time, from bright and thin to dull and round.
- Six modulation shapers you can draw by hand, usable as envelopes or LFOs.
- Deep modulation matrix where almost any parameter can be a target, including other modulators.
- Four assignable macros, plus velocity, mod wheel and aftertouch support.
- Ten built-in effects (chorus, delay, phaser, reverb, distortion, EQ and more) in a reorderable rack.
- 3D interface with visual customization, plus a Performance Mode for weaker machines.
It’s suited to generative music, polyrhythmic percussion, ambient textures and unusual basses, less to people who just want quick presets.
Compatibility
