Roland

Modern lines such as AIRA, Boutique, and Fantom keep those sounds alive while adding fresh capabilities. Roland’s legacy is reliability, innovation and cultural impact.

49-Key

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.

Analog

Analogue is sound generation based on physical electronic circuits such as oscillators, filters, and amplifiers rather than digital processing. It produces continuously variable signals with natural drift, saturation, and harmonic character, giving sounds a distinctive warmth and movement. Analogue instruments are valued for their hands-on control, immediacy, and expressive response in both studio and live performance environments.

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.

Voice

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.
