The HydrasynthDesktop / Rack has the same great sound engine as the Hydrasynth Keyboard.

Offering 8-voice polyphony, "Mutator" waveshaping, and a 32-slot modulation matrix, the ASM Hydrasynth Desktop is truly a next-generation virtual analog synthesizer for modern music producers.

Rivaling the sonic capabilities of many popular software synthesizer plug-ins, each voice features three WaveScan oscillators offering 219 different waveforms, with four Mutators total for extensive waveshaping. There's a ton of potential for creating nuanced, nonlinear sounds - the five ADSR envelope generators offer delay and hold and can have either linear or exponential curves between stages, and the five LFOs offer a total of 11 waveshapes plus delay, fade in, and smoothing. Factor in 24 performance pads with polyphonic aftertouch, plus CV/Gate connectivity, and the ASM Hydrasynth Desktop could be the versatile module your synthesizer rig is waiting for.

Extensive modulation capabilities
With its 32-slot modulation matrix, the Hydrasynth Desktop empowers you to create incredibly nuanced and expressive sounds. Synthesists are particularly impressed with its envelope generators (five per voice), which offer delay and hold in addition to ADSR stages. Each stage of the envelope can sweep through exponential and logarithmic curves, which offers big creative potential for long, evolving modulations.

Like most of the functions on Hydrasynth Desktop, envelopes can be locked to BPM for tempo-synced modulations. Combined with the looping function, you can use the envelopes as LFOs with interesting waveshapes. And speaking of LFOs, Hydrasynth Desktop offers five LFOs per voice with 11 total waveshapes. That includes the 8-step LFO, which allows you to create your own custom waveshape.

Advanced real-time control via eight macro controls
One of the most popular aspects of software synthesizers is the ability to control multiple parameters simultaneously via macro controls, and the ASM Hydrasynth Desktop gives you that creative power in hardware form. You can customize its eight macro controls to tweak up to eight destinations simultaneously. And with a total of 170 modulation destinations to explore, you can easily use the macro controls to warp between completely distinct sound variations on the fly.

Deep synthesis with an intuitive interface
While the Hydrasynth Desktop engine is remarkably powerful, it's relatively simple to find and tweak the parameters you're looking for. On the front panel, you'll find a graphic representation of the audio path, with buttons to select each individual section (individual oscillators, mixer, effects, and so on). Selecting a section brings its associated parameters to the display, with eight encoders ready to tweak. In other words, every section of this synth can be accessed with a button press, no menu diving required.

  • 24 RGB pads with polyphonic aftertouch, which also offer quick access to secondary functions via "SHIFT + Pad"

  • 5 LFOs per voice, with 11 waveforms - Sine, Triangle, Saw Up, Saw Down, Square, Pulse27%, Pulse13%, S&H, Noise, Random, and Step
  • Powerful arpeggiator with 8 modes, including chord and phrase modes
  • 32-slot Mod Matrix provides ample options for manipulating your sounds

gloves without a gauntlet
Color: (001) Black / Black / Reflective, Size: Medium
Needed short gloves with no gauntlet - these are great! Not super thick, but I didn't want heavy gloves for walking. Fit just as expected, I used the measurements suggested on the UA website. So far, good quality and holding up well. I plan on getting another pair!

Worked perfectly for a long, cold run!
Color: (001) Black / Black / Reflective, Size: Medium
These worked perfectly! They aren’t the warmest but do the job for long cold runs in Texas. I ran a half marathon in 40 degree weather with these on and they kept me warm. They are a bit smaller in size, similar to what other reviewers have said. But I’m a small woman with small hands so the size medium I ordered were perfect. They were warm enough that I took them off at about mile 6. So overall, I’d definitely recommend for a light coverage, snug fit, glove.

Decent UA gloves pricey for the quality
Color: (001) Black / Black / Reflective, Size: Large
The thickness isn’t what I thought it would be. They’re ok for warmth as long as it isn’t single digits or in the negatives. They’re durable so far and grip is good. The size and fit are good for smaller to medium sized hands. It is also good for pressing your phone screen.
