Ashun Sound Machines (ASM) has introduced the Diosynth, an expressive wind synthesizer that they say combines a deep synthesis engine with a sample playback engine to blend the best of acoustic and electronic sounds.
Designed with wind players in mind, Diosynth features mechanical keys that replicate the feel of real sax and wind instruments—avoiding the flat button-style controls found on other wind synths. Multiple fingering modes, scale/key locking, and octave keys covering over eight octaves, provide a familiar and versatile playing experience.
For expression, Diosynth includes breath and bite sensors, an internal gyro, X/Y joystick, two pressure pads, and three programmable switches. Connectivity features include ¼” stereo output, headphone jack, both with dedicated volume controls, MIDI DIN In/Out, USB MIDI & Audio In/Out, Bluetooth MIDI In/Out, and Bluetooth audio-in for playing along with music streams. Users can listen via the built-in speaker or headphones.

osynth’s sound engine is based on the Hydrasynth, but with the addition of a sample playback oscillator. This expands the instrument’s sound design possibilities into more emulative territory, letting you create patches using sampled sounds, or combining realistic acoustic sounds with wavescan oscillators – and then running the result through a 16-mode filter.
It can also layer or split two sounds at once, combining four Hydrasynth oscillators and two sample-based voices.
For the Diosynth, ASM sampled 128 unique reed, brass, fipple, and string-based sounds, including rare instruments such as the contrabass flute, Eb Tubax, and Peruvian llama whistle. Diosynth includes 384 factory patches and 768 total patch locations, covering everything from traditional wind instruments such as saxophones, trumpets, and flutes to synth leads, basses, and tempo-synced electronic textures.
Diosynth is powered by an included USB-C adaptor or by two 18650 rechargeable batteries (not included). A companion Mac/PC editor and iOS/Android app streamline patch editing and live performance control. Each unit comes with a hard-shell case, cables, and accessories, along with a stand for convenient storage.

Pricing and Availability:
Diosynth is expected to be available in December 2025, priced at $1,349 USD / MAP: $1,099 USD.
As an actual wind synth/sax player, I was not asking for this. I hope it does ok out there.
This looks like another excellent synth from ASM, and one that probably leapfrogs over existing electronic wind instruments in terms of capabilities.
But I do wonder why this is their second synth line. Is there a big audience for wind instruments?
Also – I wonder if there’s any plans to make the expanded synth engine available to keyboard players!
Same engine, plus samples. Just another repack, really.
Although synths and synth users tend to take up quite a bit of the limelight there is a massive market for “other” electronic instruments
You’ll see them at any of the big music industry conferences. Electronic Wind Instruments, Accordions, Percussion… tons of stuff that are not synths, drum machines or eurorack
All the big dogs cater to it and always have. Roland, Yamaha, Korg, Akai, Casio. Plus a ton of smaller less well known companies that specify in one or two things
Stuff for working musicians. Definitely they make up a greater portion of the sales for these companies than us synth and drum machine people
Wow! How cool is that? Maybe I should learn the Böhm-system after all??
This looks awesome. I love my EWI USB, but have been interested in wind synths with onboard sounds. None have quite lived up to what I want, but I love the sound of the hydrasynth and it sounds like they’ve done a good job on the sample oscillator. Definitely interested.
Playing synth with a guitar is a near-ultimate path for getting tons of expression going. Woodwinds aren’t far behind it, especially here. It gives the term “pro” new depth. I do wonder about the likely buyer base. How many people are really playing full-sized woodwind controllers? Enough for several to be available, clearly.
Most seem to choose near-acoustic sounds, with synth things trailing. I have serious appreciation for Adrian Belew’s defining guitar-synth work. I think I’m casually scanning for the woodwind player who hits that kind of high mark. Ashun has clearly brought it within easier reach. Hell of a toy!
They could have chose a better sound.
Didn’t see this coming.
Er. I was hoping for a non wind-based instrument. At least ASM is no longer a one synth company with the launch.
This is not for me – but you have to give ASM credit for going from nowhere in a instrument category to completely dominating established players.
Now, how about a nice analog synth with poly aftertouch?
As a brass player who also plays a fair amount of keys, I do love using breath to control sound. As a non-woodwind player, I’m glad we’ve been seeing more breath controller options in recent years.
I was really hoping Photon would have seen the light of day by now. Perhaps one day.
Cool new windsynth with high end features and organic sounds. Will it be available in Europe too ?
