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.

A 49-key instrument offers a balanced keyboard size that supports expressive playing while remaining manageable in size. It provides enough range for two-handed performance, chord work, and melodic lines without the bulk of a full-sized keyboard. For example, a 49-key synthesiser is often used in studios and live setups where versatility and portability are equally important.
Polyphonic is the ability to play multiple notes at the same time. Polyphonic instruments allow chords, layered harmonies, and complex musical passages, making them suitable for pads, harmonic textures, and expressive performance.
A synthesizer is an electronic instrument that generates and shapes sound using oscillators, filters, envelopes, and modulation sources. It allows sounds to be created from scratch, altered in real time, and controlled through keys, sequencers, or external controllers. Synthesizers are used to produce everything from basses and leads to pads, textures, and experimental sound design in both studio production and live performance.
