ASM Leviasynth: The Most Ambitious Synth of 2026?

video upload by Starsky Carr

"So much more than a DX7 on steroids. In this hands-on walkthrough I program the Leviasynth from scratch to show what Ashun Sound Machines' 16-voice hybrid synth (the long-awaited Hydrasynth successor) can really do: 8 oscillators per voice, 144 algorithms, 7 modulation types, I even demo wavetable-style tones, deep DHDSR envelopes and that gorgeous new analog filter.

I'll show you how it sounds, how it's built and exactly how to start programming it — from a classic Prophet-5 patch to dirty FM basses, glassy vintage-digital pads and modular-style generative patches. By the end you'll understand the workflow and whether the Leviasynth deserves a place at the centre of your studio.

🎹 ABOUT THE LEVIASYNTH
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
The ASM Leviasynth is a 16-voice, 8-oscillator algorithmic hybrid synthesizer from Ashun Sound Machines — the team behind the Hydrasynth. It pairs an advanced digital engine (144 algorithms, 7 synthesis types, 300+ waveforms, FM, phase distortion, phase modulation, pulse-width modulation and sync) with a brand-new pure analog 4-pole resonant filter featuring custom pre-drive saturation. Add 13 envelopes, 5 LFOs, a deep mod matrix, a 3-track sequencer, arpeggiator, Polytouch polyphonic-aftertouch keybed and ribbon controller, and you have one of the most powerful synths released in years. Available in keyboard and desktop versions."
