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.

Eurorack is a modular synthesis format with standardised dimensions, power connections, and signal levels. Eurorack systems are built from individual modules mounted in cases, allowing users to create highly customisable instruments tailored to specific sound design and performance needs.
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.
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.
