ASM

ASM (Ashun Sound Machines) is a modern synthesiser manufacturer best known for the Hydrasynth range. The company was founded by engineers with long experience in digital synthesis and instrument design, with a clear focus on expressive control and deep sound design rather than retro emulation.

ASM synthesisers are centred around wavetable-based digital synthesis combined with very powerful modulation, polyphonic aftertouch (or polyphonic pressure), and performance-focused controls. The Hydrasynth instruments are widely respected for their flexibility, modern sound, and ability to respond dynamically to how a musician plays, making them popular with sound designers, electronic musicians, and forward-thinking keyboard players.

For SynthForSale, ASM fits into the modern digital synthesiser category — instruments designed for musicians who want depth, expressiveness, and contemporary synthesis tools rather than vintage analogue recreations.

Tags

Digital

Products using digital sound generation, processing or control. Digital instruments can offer precise recall, extensive polyphony, sampling and complex synthesis methods, often combining a wide tonal range with compact hardware and flexible modulation.

Polyphonic

Instruments capable of playing multiple notes or voices at the same time. Polyphony supports chords, layered pads and overlapping notes, although the available voice count and how voices are allocated vary between instruments.

Synth

Products centred on electronic sound generation and synthesis. This tag brings together keyboard, desktop, modular and performance instruments that create or substantially shape their own sounds rather than serving only as controllers.
