ASM (Ashun Sound Machines) Hydrasynth Deluxe
1 800.00 street price

The Hydrasynth Deluxe is the flagship model in the Hydrasynth lineup, offering the most comprehensive feature set and maximum polyphony. This professional-grade synthesizer features a full-sized 73-key semi-weighted keyboard with revolutionary Polytouch® polyphonic aftertouch technology, enabling individual note expression and control. The instrument delivers exceptional versatility with 16 voices in single mode and supports sophisticated multi-timbral operation with 2 layers of 8 voices each in multi mode.

The Deluxe model stands out with its ability to split and stack voices, making it ideal for complex performances and studio work. Its extensive control surface includes a comprehensive set of knobs for real-time parameter manipulation, including dedicated sections for arpeggiator control, macro assignments, and performance filter control. The inclusion of a ribbon controller with theremin mode adds an extra dimension of expression, while backlit pitch and modulation wheels provide precise control in any lighting condition.

Connectivity is extensive, featuring both USB and traditional DIN MIDI with full MPE support, comprehensive CV/Gate inputs and outputs for modular integration, and multiple audio outputs including both rear balanced outputs and front-mounted headphone connections. The robust steel chassis construction ensures durability for professional use.
