ASM Hydrasynth

Wave Morphing Synthesizer

With the Hydrasynth Deluxe ASM (Ashun Sound Machines) presents a 16-voice digital keyboard synthesizer with Wave Morphing synthesis. The enormous variety of functions paired with the first-class sound testifies to the many years of experience of the development team. The specially developed "Polytouch Keybed" is a velocity sensitive 73-key keyboard with polyphonic aftertouch (MPE). The pitch and modulation wheels have also been ergonomically redesigned. With minimal menu work (paging) in mind, the user interface has been designed and functions placed one keystroke away. Eight encoders with LED rings and a large OLED display provide adequate access to all parameters and an optimal overview.

Thanks to the chord function and the very extensively programmable arpeggiator, you have two very powerful creative tools at your fingertips to work out your ideas on stage as well as in the studio. The Hydrasynth Deluxe comes from the factory with two preset banks of 128 sounds each; a total of five banks with a total capacity of 640 sounds are available. In addition, the Deluxe version has a multimode and can thus play two sounds (lower/upper part) with eight voices each on different MIDI channels at the same time. As with the original Jupiter 8, the mix between the two sounds can be adjusted directly with a knob.

A small highlight are the five analogue outputs for CV, Gate, Clock and two definable controllers, making this synthesizer the control center of a connected modular system! So that the synth itself can be the beneficiary of control voltages, two CV inputs have been implemented that sample up into the high audio range. Out with Gate and in with "Maths", assign this to the Cutoff in the modulation matrix; there are no limits to creativity.

Sound creation

Three full-fledged oscillators draw their base material from 219 waveforms. Oscillator 1 and 2 are furthermore capable of wave scanning, where up to eight waveforms can be crossfaded respectively morphed. By means of four "mutants" the oscillators can be further shaped; besides FM, three different types of pulse width modulation (PWM), Hard-Sync and Harmonic-Sweep there is Wavestack. With the latter you can create assertive unison/supersaw sounds with only one oscillator. The repertoire is rounded off with a noise generator and the ring modulator.


With two different filters that can be operated in parallel or in series, nothing stands in the way of detailed sound shaping on the Hydrasynth. The first filter covers eleven different filter models (including 12/24 dB lowpass, highpass, vocal). The second filter is a state-variable filter with a slope of 12 dB and is continuously variable from Lowpass via Bandpass to Highpass (similar to the SEM filter).


The last link in the signal chain are four effect blocks to give the sound the final touch. The first and last effect blocks each contain the same selection from Chorus, Flanger, Rotary, Phaser, Lo-Fi, Tremolo, EQ, and compressor (with sidechain). In between, Delay and Reverb (five respectively six variations) can be activated.

Modulation & Controller

What would such an oscillator and filter setup be without modulation! Five loopable DAHDSR envelopes and five synchronizable LFOs with several waveforms and trigger modes including a sixth vibrato LFO provide plenty of movement in the sound. Besides some fixed modulation connections, almost every parameter in the Hydrasynth Deluxe can be modulated via the modulation matrix, which comprises 32 slots.

Absolutely performance-suitable and a guarantor for even more fun with the instrument is the 67 cm long Ribbon Controller, which can not only be used to modulate other parameters, but also offers a completely different and also new method of note input in Theremin mode.

Utility Shelf

Included is the so-called Utility Shelf, the removable metal piece extends the free space on the right half of the case a few centimeters, so a laptop or other musical instrument finds the necessary space on the Hydrasynth Deluxe.
