ASM HydraSynth Desktop Digital Poly Synth 

The ASM 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. 

One problem with many desktop or rack synths is that you usually have to connect them to an external controller to play them.  The idea behind having a rack or desktop unit you can put anywhere is that it is out of the way. This is fine until you want to start doing some sound editing or adjusting it in real-time. Then you want a way to play it​​. We have included 24 polyphonic pressure sensitive pads that allow you to actually play the synth. With multiple pad layouts to choose from as well as multiple scales, playing the Hydrasynth Desktop is its own musical experience. 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 wavetables. Creating user wavetables is arduous or downright impossible. Unlike most wavetable synths, our oscillators 1 & 2 have our WAVELIST mode. This mode allows you to pick and choose 8 waves, from our 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 Mutants 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.
