From afar, Ahsun Sound Machines’ Hydrasynth Explorer doesn’t look very special, however once you delve into what it can do, you realize its potential. It includes the same 8-voice sound engine that the original Hydrasynth offers but is more compact and battery-powered, and 37 note polyphonic aftertouch mid-sized keys.
When it comes to creating sounds, the Explorer’s three WaveScan oscillators allows you to choose from 219 waveforms. While two of those oscillators can be combined with Mutators, giving you the freedom to bend, create and modulate the sound in a variety of ways. Each “mutant” allows you to choose from several processes: FM-linear, hard stack, pulse width, harmonic sweep, and more.
As for its filters, the Hydrasynth has two filters that can be configured in series or parallel. Most notably, the first filter has 16 different models, allowing for more customization. Whereas the second is 12db per octave with a continuous sweep from either low pass to high pass via bandpass, or low pass to high pass via notch.
The Hydrasynth Explorer’s other features include five low-frequency oscillators, five DAHDSR envelopes, 32 user definable modulation routings, pre- and post-effects, micro-tuning support, and CV/Gate interconnectivity.
In short, ASM’s Hydrasynth Explorer offers plenty of depth inside its compact structure.
