Elastic OSC is a synthesizer app based on the DSP code of the Mutable Instruments Plaits hardware oscillator module, one of the most beloved (and cloned) oscillator modules in the Eurorack modular scene! Like the original, Elastic OSC comes with a wide variety of possible sounds, from analog-style, FM, and additive sounds to physical modeling, percussive, and even drum sounds. 

Elastic OSC can be used in both monophonic and 8-voice polyphonic modes. You can play the app using the (on-screen) keyboard or an external keyboard or sequencer inside your DAW of choice.

The app focuses on ease of use, featuring two XY pads for intuitive sound manipulation of the OSC engine and the effects. Despite the simplicity of the cleaned-up interface, the sound possibilities are vast – thanks to 24 different oscillator models and the ability to automate parameter changes, as it is possible in all Elastic apps released so far.

A versatile Arpeggiator makes it easy to start with simple ideas or can already create entire sonic worlds.

Elastic OSC includes an integrated help system (tap “?”) to provide explanations for nearly every GUI element, the underlying DSP model, and most of the app’s functionality.
