Deimos

Deimos is a characterful synth plugin designed to be compact, quick and easy to use.

On the surface, Deimos functions like many other virtual analog synths, allowing users familiar with them to quickly find themselves at home. However, it goes beyond typical virtual analog capabilities and limitations, offering phase distortion/modulation options, more waveforms, and flexible modulation.

Almost all controls are accessible from the main panel to make exploring and tweaking sounds as immediate as possible.

Deimos was chosen as the synth for the monthly KVR One Synth Challenge during May 2026.
It's a friendly challenge where musicians limit themselves to a single synth plugin to create an entire track of music exclusively with it.
