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.

A synth, short for synthesiser, is an electronic instrument used to create and shape sound using oscillators, filters and modulation. Synths can produce everything from classic analogue-style tones to complex, evolving textures used across many styles of music. If you enjoy exploring sound design and creating unique voices rather than simply reproducing traditional instruments, synths offer a deeply creative and expressive way to make music.

8-voice indicates that an instrument can play up to eight notes simultaneously. It is used to perform chords, layered harmonies, and sustained parts without notes cutting off. For example, an 8-voice synthesiser allows complex chord voicings or evolving pad sounds to be played smoothly while maintaining clarity and balance across each note.
Desktop refers to instruments designed for tabletop or studio use rather than keyboard-based performance. Desktop units are compact, self-contained devices controlled via knobs, buttons, sequencers, or external controllers, making them ideal for studio workflows and modular setups.
A synth is an electronic instrument that creates sound through electronic signal generation and shaping. It is used to produce basses, leads, pads, textures, and effects by controlling oscillators, filters, envelopes, and modulation. Synths are central to electronic music and modern production, offering flexible sound design for both studio work and live performance.
Synth for Sale has over 1000 used synths and gear like that for sale. We bring these products to you via our trusted partners, retailers and direct with independent sellers in the UK.
A voice is a single complete sound path within an instrument, typically made up of an oscillator, filter, amplifier, and modulation. It determines how many notes can be played at once and how each note is shaped. For example, an instrument with multiple voices can play chords and layered parts, while each voice handles the sound of one note independently.
Wavetable is a method of sound generation that uses a collection of digital waveforms stored in tables. It is used to create evolving and complex tones by smoothly scanning or switching between different wave shapes. For example, wavetable synthesis can be used to produce moving pads, shifting basses, or textured leads that change character over time.
