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.
The Important stuff
1981. 1984. 37-Key — A 37-key instrument is a compact keyboard designed for portability and space-efficient setups. It provides enough range for melodies, bass lines, and chord work while remaining easy to transport and fit on a desk or small studio rig. For example, a 37-key synthesiser is often used for live performance or desktop production where quick access and minimal footprint are more important than a full keyboard range.
. Monophonic — Monophonic is the ability to play only one note at a time. It is used for focused, expressive parts where pitch, articulation, and modulation are more important than chords. For example, a monophonic instrument is often used for bass lines or lead sounds, allowing smooth note transitions, slides, and detailed control over dynamics and movement.
. Synthesizer — 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..
