ASM Diosynth Wind Synth: Hydrasynth Follow-up Features Wavescan & Sample Playback Oscillators
Mechanical keys, breath and bite sensors, and an internal gyro bring realism and expressiveness to your playing.
ASM has finally released the successor to the Hydrasynth, and it’s… a wind synth? In a surprise move, ASM has announced the Diosynth Wind Synth, which includes a sound engine based on Hydrasynth’s wavescan oscillators, plus additional sample playback for both realistic and sci-fi sounds.
ASM Diosynth Wind Synth
Ashun Sound Machines’ Hydrasynth is one of the top modern synthesizers. Unabashedly digital, its advanced wavetable sound engine is stunningly beautiful. ASM has released a number of variations on the Hydrasynth theme since the first instrument came out in 2020, with three different keyboard versions and a desktop model all available, plus limited edition colorways.

I’ve been longing for a new instrument from ASM for a couple of years now, and that day has finally come. The official successor to the Hydrasynth has been announced, and it’s… not the Leviasynth but the Diosynth.
Maceo, Blow Your Horn
Diosynth is a wind synthesizer. Like Roland’s Aerophone series and Akai’s EWIs, Diosynth Wind Synth combines digital synthesis with the expressiveness of acoustic wind instruments.

ASM’s new instrument offers six oscillators, four of which are based on Hydrasynth’s wavescan oscillators, and the other two dedicated to sample playback duties. ASM has sampled 128 unique reed, brass, fipple, and string-based sounds for the instrument. This includes rare instruments such as the contrabass flute, Eb Tubax, and Peruvian llama whistle.
The sound engine also features a 16-mode filter, noise generator, Growl section, EQ and insert FX, plus an extensive modulation section. It can do layers or splits of up to two sounds simultaneously. To help with patch programming, there is a companion editor for Mac/PC and iOS/Android devices.

The new wind synth includes 384 factory patches and 768 total patch locations, reportedly covering everything from “traditional wind instruments such as saxophones, trumpets, and flutes to synth leads, basses, and tempo-synced electronic textures,” according to ASM.
Keys to Success
Wind players should feel at home with the Diosynth, as it features mechanical keys that replicate the feel of real sax and wind instruments, according to ASM. It supports multiple fingering modes, scale/key locking, and octave keys covering over eight octaves.

In terms of expression possibilities, Diosynth includes breath and bite sensors, an internal gyro, X/Y joystick, two pressure pads, and three programmable switches.
Connectivity and Power
Diosynth appears to be fully stocked in terms of connectivity, with quarter-inch stereo output, eighth-inch headphone jack (both with dedicated volume controls), MIDI DIN in/out, USB MIDI and audio in/out, Bluetooth MIDI in/out, and Bluetooth audio-in for playing along with music streams. It also sports a built-in speaker.

Power comes courtesy of the included USB-C adaptor or by two 18650 rechargeable batteries (not included).
Price and Availability
I have to say, I was a little surprised to learn that Diosynth was a wind instrument and not a new keyboard synth. It will be interesting to see if any of the technology associated with the Diosynth, such as the sample playback engine, makes it into the Hydrasynth via a firmware update or into a new, future instrument.
Diosynth will be available in December 2025 with an MSRP of $1349 / €1449 / £1249. Each unit will come with a hard-shell case, cables, accessories, and a stand.
ASM instruments are available at Thomann*.
