Independent shopping perspective
The Korena take
Hydrasynth Keyboard is a 49-key wave morphing synthesizer centered on Polytouch polyphonic aftertouch: pressure can shape notes individually within a chord. Its 8-voice wavetable engine combines wavemorphing oscillators, a fixed-wave third oscillator, dual filters, and extensive modulation for detailed patch building. The four-octave ribbon, pitch and modulation wheels, eight macro controls, and balanced stereo outputs give hands-on access to performance changes and studio routing. MIDI, USB MIDI, and multiple CV/Gate standards support connected hardware and software setups.
Strong match
Who this is for
- Performing chords where pressure changes need to affect individual notes independently.
- Building animated patches with wavemorphing, five LFOs, five envelopes, and 32 modulation slots.
- Connecting a keyboard synth to MIDI, USB MIDI, or multiple CV/Gate standards.
Consider the trade-offs
When to look elsewhere
- Players who need more than 49 keys on the instrument.
- Setups needing an unweighted key action; this model uses semi-weighted keys.
