The Hydrasynth Desktop delivers the complete Hydrasynth synthesis engine in a compact, keyboard-less format designed for desktop production and modular integration. This unique model replaces traditional keys with 24 velocity and pressure-sensitive color LED pads that feature Polytouch® technology, offering scale and alternate layout modes for creative performance approaches. The pad-based interface opens up new possibilities for beat-making, chord triggering, and experimental playing techniques.

With 8-voice polyphony and the full Hydrasynth sound engine, the Desktop model provides all the sonic capabilities of its keyboard counterparts in a space-efficient package. The control interface is optimized for desktop use with dedicated sections for arpeggiator control (4 knobs), comprehensive macro control (8 knobs and buttons), and performance filtering. While it lacks the ribbon controller of the keyboard models, it maintains professional connectivity with extensive CV/Gate integration and complete MIDI implementation.

This model excels in studio environments where space is at a premium or where integration with other hardware is priority. The steel construction ensures durability despite the compact form factor, while the comprehensive connectivity options make it an excellent choice for hybrid setups combining traditional and modular synthesis approaches.
