    ASM Hydrasynth Explorer Synthesizer

    The ASM Hydrasynth Explorer proves that great things come in small packages — battery-powered ones, no less. This 8-voice polyphonic wave morphing synthesizer squeezes the full Hydrasynth sound engine into a compact, grab-and-go format, complete with a 37-note PolyTouch keybed, MPE compatibility, and enough modulation routing to keep sound designers happily lost for hours. Once you get your hands on it, you'll wonder why you ever needed a bigger synth.

    ASM Hydrasynth Explorer A Sound Engine That Refuses to Think SmallASM Hydrasynth Explorer A Sound Engine That Refuses to Think Small

    A Sound Engine That Refuses to Think Small

    Despite its portable frame, the Explorer's synthesis engine is anything but miniature. Three WaveScan oscillators per voice pull from a library of 219 waveforms, while four Mutator waveshapers let you push, bend, and mangle those waveforms into something entirely your own. With dual filters configurable in series or parallel, you have serious tone-shaping horsepower at your fingertips.

    • WaveScan Oscillators with 219 Waveforms: Each of the three oscillators per voice can scan across a massive palette of waveforms, giving you access to wavetable, FM, WavePWM, and subtractive synthesis methods all from one box.
    • Dual Filters Per Voice: A multimode filter (11 types) and a variable LP/BP/HP filter work together in series or parallel, giving you tight, surgical tone control or wide, sweeping filter textures depending on your mood.
    • Four Wave Mutators for Deep Waveshaping: With seven Mutator types — including FM-Lin, WaveStack, Hard Sync, and Harmonic Sweep — you can take any waveform from silky smooth to gloriously chaotic without breaking a sweat.

    Modulation and Performance That Means Business

    If you're the kind of player who likes to make every note do something interesting, the Explorer will feel like home. Its 32-slot modulation matrix, five envelope generators per voice, and five LFOs per voice give you a level of expressive, per-note control that most hardware synthesizers simply can't match — polyphonic aftertouch included.

    • PolyTouch Polyphonic Aftertouch Keybed: The Explorer's proprietary 37-key PolyTouch keybed senses individual pressure per note, giving you the kind of expressive, per-voice control previously reserved for high-end vintage instruments and, apparently, people with very sensitive fingers.
    • 32-Slot Modulation Matrix with 170 Destinations: Nearly every parameter on the Explorer can be a modulation destination, and with five ADSR envelope generators and five LFOs per voice — each with 11 waveform options — your modulation possibilities are effectively endless.
    • 8 Macro Controls for Real-Time Sound Morphing: Assign up to eight parameters to each macro knob and reshape your patches on the fly. Combined with MPE compatibility and pitch/mod strips, live performance gets a serious upgrade.

    Portability and Connectivity That Goes Wherever You Do

    This is where the Explorer really earns its name. Battery-powered operation via 8x AA batteries means you're not looking for a power outlet in the park, on the tour bus, or at 3am in a studio without a free socket. But portability doesn't mean compromising your setup — the Explorer still connects directly into modular ecosystems without hesitation.

    • Battery-Powered Operation: Run the Explorer on 8x AA batteries for genuinely cable-free performance and studio sessions. It's a full-featured professional synthesizer that can technically operate from a corner store purchase.
    • CV/Gate Connectivity for Modular Integration: Plug directly into any modular or semi-modular synthesizer setup using the Explorer's CV/Gate I/O, making it a surprisingly flexible centerpiece for hybrid modular-hardware rigs.
    • 640 Preset Locations with Category Search and Microtuning Support: A deep preset library with category-based searching keeps your sounds organized, while MIDI Tuning Standard file support opens the door to alternate temperaments and microtuning experimentation.

    The Explorer Is Worth Every Bit of the Hype

    The ASM Hydrasynth Explorer delivers one of the most complete and expressive hardware synthesis experiences at its price point — all in a battery-powered, compact form factor you can take anywhere. Whether you're a sound designer, live performer, or modular enthusiast, this synth doesn't just punch above its weight class; it's competing in an entirely different league.

    Frequently Asked Questions

    Yes, the Explorer features ASM's proprietary PolyTouch keybed, which delivers polyphonic aftertouch on all 37 keys independently. You have full control over aftertouch curves, offsets, and release times, making it one of the most expressive hardware synthesizers in its price range.

    The core sound engine is identical across both models. The main differences are form factor and key size: the Explorer has 37 mid-sized keys and battery-powered operation, while the Keyboard offers 49 full-sized keys and is designed more for stationary studio or stage use.

    Yes, the Hydrasynth Explorer is fully MPE (MIDI Polyphonic Expression) compatible. This allows it to receive per-note expressive MIDI data from MPE controllers or send that data to compatible software and hardware.

    The Explorer has a relatively intuitive interface for the depth it offers. Each section of the synth is accessible with a single button press, with no deep menu diving required. That said, its synthesis engine is genuinely deep, so beginners with an interest in sound design will find plenty of room to grow without hitting a ceiling anytime soon.

    Yes, the Explorer includes CV/Gate connectivity, allowing it to integrate directly with modular and semi-modular synthesizer setups. This makes it a versatile centerpiece for hybrid rigs, whether you're using it as a controller, a sound source, or both.
