Brand
Kurzweil is an American music technology brand best known for high-end keyboards, synthesisers, and digital pianos, with a strong heritage in sound design and expressive playability. The company was founded in the 1980s by Ray Kurzweil, with an early focus on advanced sampling and realistic instrument emulation.
They’re particularly respected for their V.A.S.T. synthesis engine (Variable Architecture Synthesis Technology), which allows deep sound shaping and complex signal paths, making Kurzweil instruments popular with professional players, composers, and studios. Their keyboards are often used for stage performance, film scoring, and serious production work, blending classic sounds with powerful modern synthesis.
For SynthForSale, Kurzweil sits firmly in the premium keyboard and synthesiser category — instruments built for musicians who value depth, realism, and long-term reliability over quick presets or trend-driven features.

A 76-key instrument offers an extended playing range that sits between standard keyboards and full piano-length designs. It is used for expressive two-handed playing, complex arrangements, and layered parts while remaining more portable than an 88-key instrument. For example, a 76-key keyboard is often chosen by performers who need wide range and flexibility without the size and weight of a full piano keyboard.
Keyboard refers to electronic keyboards used for playing, composing, and performing music, ranging from simple digital keyboards to advanced synthesizer-based instruments. On SynthForSale, keyboards include instruments designed for studio production, live performance, and home use, often featuring velocity-sensitive keys, built-in sounds, MIDI connectivity, and integration with computers and other hardware. They are commonly used across electronic, pop, ambient, film, and experimental music, and can function as standalone instruments or as controllers for software and modular setups.
Portable keyboards and pianos are lightweight, compact instruments designed for easy transport without sacrificing playability. They deliver a wide range of sounds, built-in features, and practice tools, making them popular with beginners, students, and travelling musicians.
Many models include battery operation, onboard speakers, and connectivity options, so you can play anywhere — at home, on stage, or on the move. Despite their smaller size, portable instruments often feature weighted or touch-sensitive keys for expressive playing.
Perfect for learning, rehearsing, or performing, portable keyboards and pianos combine convenience with versatility.
