The sound engine is designed for maximum flexibility. At the same time, we designed the user interface in a way to allow you to edit the patch quickly with a minimal amount of paging and many workflow shortcuts.

​Utilizing an advanced wavetable synthesis engine, 3 Oscillators, dual Wave Mutators and 2 filters that can be configured in series or parallel, the tone generating capabilities are unmatched.

As for the performance capabilities, The Hydrasynth Desktop / Rack has 24 polyphonic pressure touch pads so that you can play the unit without needing to connect a keyboard or other controller. Using multiple pad layout modes as well as quick to access scale modes, the Hydrasynth Desktop / Rack is easy to make music on.

​The Hydrasynth Desktop / Rack comes with rack ears so that you can mount it in a standard 19" rack.
