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.
