Supplier's Notes:
The ASM Hydrasynth Deluxe is the new flagship Hydrasynth. Offering a dual-engine setup with a total of 16 voices plus an all new 73-note keybed featuring ASM's much sought after PolyTouchr polyphonic aftertouch functionality, clearly in a class of its own. With essentially two Hydrasynths in one instrument, KeySplit and Dual voice mode patches with 8 independent voices each are possible. You also have separate balanced stereo audio outputs for each of the two parts. The easily accessible 4 octave ribbon controller adds for truly expressive playing. The Hydrasynth Deluxe of course offers CV/GATE I/O for interfacing to modular and other voltage controlled synths. There's a ton of potential for sound creation, using ASM's WaveScan oscillators together with the Mutator waveshaping section and user configurable filters. A plethora of LFO's and Envelope's plus Insert and Master Effects makes this a dream sound creation tool and quite possibly the ultimate synthesizer and controller combo for your rig.

Supplier notes:
The HYDRASYNTH keyboard is both a sound designers dream synth as well as a performing musicians ideal. The sound engine is designed for maximum flexibility. At the same time, we designed the user interface in a way to allow you to edit the patch quickly with a minimal amount of paging and many workflow shortcuts.

Utilizing an advanced wavetable synthesis engine, 3 Oscillators, dual Wave Mutators and 2 filters that can be configured in series or parallel, the tone generating capabilities are unmatched.

As for the performance capabilities, The HYDRASYNTH keyboard has our proprietary Polytouch keybed that offers polyphonic aftertouch over each note, giving you the type of expressive control found only in certain vintage synths.

Add to this a 4 octave ribbon controller and ergonomically designed pitch and mod wheels and you have expression and control that is not equaled in any other hardware synthesizer on the market.

The new ASM Polytouchr keybed allows not only the standard velocity and aftertouch found on other keybeds but it also supports fully polyphonic aftertouch.

In recent years companies have been trying to find ways to give the keyboard musician more ways to better express themselves. The problem is that their solution is almost never a keyboard, so you have to learn a new technique to play them.

The Polytouch keybed features a high quality, standard sized keys, so you can start playing it instantly.

The tone generation capability is the heart of any synthesizer.

The 3 oscillators allow you to choose from a selection of 219 single cycle waveforms.

Wavemorphing is a feature usually found on synths with preset wave tables. Creating user wavetables is arduous or downright impossible. Unlike most wavetable synths, the oscillators 1 & 2 have our WAVELIST mode.

This mode allows you to pick and choose 8 waves, from the bank of 219, arrange them in the order you want, and then morph from one to another.

Oscillators 1 & 2 are routed into our MUTATORS. The Mutators allow you to modulate, bend and sculpt the sound in new (and old) ways.

Each MUTANT allows you to choose from the following processes:

FM-Linear - for making classic FM sounds. Choose multiple FM sources, including external inputs.

Wavestack- creates 5 copies of the incoming sound and allows you to set a detune amount.

Hard Sync - This gives you those classic hard sync sounds. Try hard syncing a morphing wavetable for some fun.

Pulse Width - This will pulse width modulate ANY input sound.

PW - Squeeze - This is a different form of pulse width mod that creates a smoother sound.

PW-ASM - this mode divides the incoming wave into 8 slices and allows you to set how much pulse width mod will happen in each section.

Harmonic Sweep - this will sweep the harmonics of the incoming sound.

The Mutant's can also generate its own waveforms in both FM and Sync modes so that you do not have use another oscillator....Of course the routing is flexible so you can choose the other oscillators as mod sources if you like.

The 3 Oscillators are fed into a mixer along with the Noise generator and Ring Modulator.

The Mixer allows you to mix levels as well as pan the input source.

There is a balance control that allows you to choose how much signal of each source is routed to filters 1 and 2.

The filters can be set to be parallel or series for ultimate flexibility.

If oscillators and tone generators are the heart of a synthesizer, the filters are the soul.

The Hydrasynth has two filters that can be configured in series or parallel.

The first filter has 11 different filter models, giving you multiple options for tailoring your sound.

The second filter is a 12db per octave has a continuous sweep from Low pass to bandpass to high pass, similar to the way the classic SEM filter worked.

5 DAHDSR Envelopes.

An advanced sound engine needs plenty of modulation sources. Our 6 stage envelopes feature Delay, Attack, Hold, Decay, Sustain and Release stages.

The time settings for the stage can be set in seconds or in time divisions, giving you envelopes that play in
sync to your song.

You can also loop the envelopes to create LFO's whose shape can be voltage controlled in the modulation matrix.

The modulation capabilities on the Hydrasynth are endless.

With 32 user definable modulation routings, you will have plenty of ways to use the 29 modulation sources and 155 modulation destinations.

Almost everything in the synth engine can be a modulation destination including the effects and arpeggiator.

The Modulation matrix points themselves can also become modulation destinations.

Notes: Desktop version of the mega Hydrasynth. The same amazing synth engine, paired with polyphonic, pressure-sensitive touchpads, making it an interesting creative alternative to the keyboard version.

Supplier's notes:
The HYDRASYNTH Desktop / Rack has the same great sound engine as the HYDRASYNTH Keyboard. The sound engine is a sound designers dream synth as well as a performing musicians ideal. The sound engine is designed for maximum flexibility. At the same time, we designed the user interface in a way to allow you to edit the patch quickly with a minimal amount of paging and many workflow shortcuts.

Utilizing an advanced wavetable synthesis engine, 3 Oscillators, dual Wave Mutators and 2 filters that can be configured in series or parallel, the tone generating capabilities are unmatched.

As for the performance capabilities, The Hydrasynth Desktop / Rack has 24 polyphonic pressure touch pads so that you can play the unit without needing to connect a keyboard or other controller. Using multiple pad layout modes as well as quick to access scale modes, the Hydrasynth Desktop / Rack is easy to make music on.

The Hydrasynth Desktop / Rack comes with rack ears so that you can mount it in a standard 19" rack.
