Elastic OSC is now available across all major platforms: macOS, Windows, iOS and Android. Design sounds anywhere — on your phone or tablet — then continue shaping them in your desktop workflow. One synth, every device.

An 8-voice polyphonic macro-oscillator based on Mutable Instruments Plaits, reduced to just four core parameters across all 24 oscillator models.

The four core parameters map to an expressive XY pad for fast, intuitive sound exploration. A second XY pad gives direct control over the built-in effects — immediate, playful, and fun.

The desktop version works as a plugin on Mac(AU/VST3) and PC(VST3). Tested in Ableton Live, Bitwig, Reaper, Cubase, FL Studio, and Logic Pro. MPE support and multiple LFOs are already included for free in the Desktop version.

A versatile Arpeggiator and full parameter automation make it easy to build entire sonic worlds.
