An Expression Powerhouse For Sound Designers and Musicians Alike - The ASM Hydrasynth 49-Key Digital Polyphonic Wave Morphing Synthesizer

The HYDRASYNTH keyboard is both a sound designer's dream synth as well as a performing musician's ideal. The sound engine is designed for maximum flexibility. At the same time, AMS 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 keyboard has ASM's proprietary Polytouch keybed that offers polyphonic aftertouch over each note, giving you the type of expressive control found only in certain vintage synths. Add to this a 4-octave ribbon controller and ergonomically designed pitch and mod wheels and you have expression and control that is not equaled in any other hardware synthesizer on the market-- today or ever.
