The ASM Hydrasynth Desktop is where wavetable wizardry meets hands-on performance. This compact powerhouse delivers the same legendary sound engine as its keyboard sibling but reimagined for producers and sound designers who prefer their synths rack-mounted or perched on a desktop.
With 24 polyphonic aftertouch pads, an advanced wavetable synthesis engine, and modulation options that would make a modular enthusiast blush, this synth is built for those who refuse to compromise on sound quality or creative control.
Sound Design Without Limits
The Hydrasynth Desktop doesn't just give you synthesis tools — it gives you a complete sonic laboratory. At its core are three oscillators with access to 219 single-cycle waveforms, but the real magic happens when you engage the WAVELIST mode. Unlike traditional wavetable synths that lock you into preset tables, the Hydrasynth lets you handpick any eight waveforms and morph between them however you like. It's like being a DJ, but for individual sound waves.
Three Oscillators with WAVELIST Mode: Choose from 219 waveforms and create custom wavetables by selecting eight waves, arranging them in any order, and morphing smoothly between them with the WaveScan parameter.
Dual Mutators for Sound Sculpting: Route oscillators 1 and 2 through powerful mutators including FM-Linear for classic FM tones, WavStack for instant detuned thickness, and PW-ASM for dividing waveforms into eight individually modulatable slices.
Flexible Dual Filter Architecture: Shape your sound with Filter 1's sixteen models (including modern and vintage ladder filters, MS-20, and vocal formants) and Filter 2's continuously variable SEM-style sweep from low-pass to band-pass to high-pass, configurable in series or parallel.
1,024 Patch Memory with Smart Organization: Store your sonic creations across eight banks of 128 patches each, with sorting by number, name, or category, plus a Favorites browser for instant access to your go-to sounds.
Unleash Your Modulation Mayhem
The Hydrasynth Desktop transforms every sound into a living, breathing organism with five LFOs, five envelopes, and a 32-slot modulation matrix that connects 35 sources to 191 destinations. The LFOs feature a step mode with up to 64 programmable steps, essentially giving you five mini step sequencers to automate anything your imagination can conjure. Envelopes can loop to function as additional LFOs, and nearly every parameter — including effects and arpeggiator settings — can become a modulation destination.
Five LFOs with 64-Step Sequencing: Each LFO offers ten standard waveforms plus a step mode that lets you program intricate patterns up to 64 steps long, complete with delay, fade-in, and one-shot modes.
Five Six-Stage DAHDSR Envelopes: Go beyond basic ADSR with Delay and Hold stages, adjustable slope curves, tempo sync, and envelope looping that transforms them into voltage-controlled LFOs.
32-Slot Modulation Matrix: Connect any of 35 sources to any of 191 destinations with bipolar or unipolar scaling, and route modulation slots to themselves for mind-bending meta-modulation.
Comprehensive Connectivity: Interface with modular gear via CV/Gate (supporting 1V/oct, 1.2V/oct, and Hz/V standards), traditional hardware via MIDI In/Out/Thru, and your DAW via class-compliant USB MIDI.
Rack Royalty Ready to Rock
Who says rack synths can't be expressive? The Hydrasynth Desktop/Rack shatters that stereotype with 24 velocity and pressure-sensitive RGB Polytouch pads, giving you genuine polyphonic aftertouch without needing an external MPE controller.
With multiple pad layouts and instant access to 60 scales (including microtonal flavors), this desktop unit becomes a playable instrument in its own right. Eight assignable Macro controls let you morph between sonic universes with a single twist, while the arpeggiator’s RATCHET and CHANCE parameters inject rhythmic chaos and happy accidents into your patterns.
24 Polytouch RGB Pads: Play expressively with velocity and polyphonic pressure sensitivity across multiple pad layouts and scale modes, all without connecting an external keyboard.
Eight Performance Macros: Each Macro knob and button can control up to eight destinations simultaneously, enabling complete sound transformations with minimal movement — perfect for live performance.
Advanced Arpeggiator with Phrase Mode: Beyond standard arpeggiation patterns, explore 64 preset phrases with adjustable length, step offset, and modulatable parameters including ratcheting and chance-based triggering.
Rack-Ready Metal Construction: Mount it in a standard 19-inch rack with included ears or let it live on your desktop — the solid steel and aluminum build handles life on the road.
Your Next Sound Design Obsession
The Hydrasynth Desktop is built for seamless integration into any setup. Its durable metal chassis, featuring steel top and bottom with aluminum side panels, fits neatly into 5U of rack space (rack ears included).
It’s ideal for producers seeking modular-like flexibility without the mess of cables, performers needing expressive control in a compact form, and sound designers pushing beyond creative limits.
