Brand
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.

Synths are electronic instruments designed for creating and shaping sound, from classic analogue-style tones to modern digital textures. Used for basslines, leads, pads and experimental sound design, they play a central role in many styles of music. If you enjoy hands-on creativity and exploring new sonic ideas, synths offer a powerful and expressive way to make music.

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.
Dual indicates that an instrument or module contains two identical or complementary sections. This can apply to oscillators, filters, envelopes, or channels, allowing parallel processing, stereo operation, or more complex sound design within a single unit.
A module is a self-contained unit designed to perform a specific function within a larger system. Modules are commonly used in modular and Eurorack setups, where each unit handles tasks such as sound generation, modulation, filtering, or control, allowing systems to be built and expanded piece by piece.
New Gear is unused and in original condition, supplied as it leaves the manufacturer. It is chosen for guaranteed reliability, full functionality, and the assurance of manufacturer support. For example, buying new ensures access to the latest design revisions, included accessories, and official warranty coverage.
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.
