ASM Hydrasynth Keyboard

Extensive modulation capabilities
With its 32-slot modulation matrix, Hydrasynth empowers you to create incredibly nuanced and expressive sounds. Synthesists at Sweetwater are particularly impressed with its envelope generators (five per voice), which offer delay and hold in addition to ADSR stages. Each stage of the envelope can sweep through exponential and logarithmic curves, which offers big creative potential for long, evolving modulations.
Like most of the functions on Hydrasynth, envelopes can be locked to BPM for tempo-synced modulations. Combined with the looping function, you can use the envelopes as LFOs with interesting waveshapes. And speaking of LFOs, Hydrasynth offers five LFOs per voice with 11 total waveshapes. That includes the 8-step LFO, which allows you to create your own custom waveshape.

Amazing performance potential with PolyTouch and ribbon controller
Whether you're performing or recording, Hydratouch delivers an incredibly expressive playing experience, especially when you dig into its PolyTouch capabilities. PolyTouch is a new method of polyphonic aftertouch sensing. You have full control over aftertouch curves, offsets, and release times, giving you big creative potential when using aftertouch to manipulate your sounds. A built-in ribbon controller expands your performance options further — it can control pitch bend or modulation amount, and a Theremin mode allows you to play melodies on the ribbon controller against whatever you're playing on the keyboard.

Deep synthesis with an intuitive interface
While the Hydrasynth engine is remarkably powerful, it's relatively simple to find and tweak the parameters you're looking for. On the front panel, you'll find a graphic representation of the audio path, with buttons to select each individual section (individual oscillators, mixer, effects, and so on). Selecting a section brings its associated parameters to the display, with eight encoders ready to tweak. In other words, every section of this synth can be accessed with a button press, no menu diving required.

Advanced real-time control via eight macro controls
One of the most popular aspects of software synthesizers is the ability to control multiple parameters simultaneously via macro controls, and the ASM Hydrasynth gives you that creative power in hardware form. You can customize its eight macro controls to tweak up to eight destinations simultaneously. And with a total of 170 modulation destinations to explore, you can easily use the macro controls to warp between completely distinct sound variations on the fly.
