The renowned 61-key Roland D-50 digital synthesizer, which debuted in 1987, is credited with creating Roland’s “Linear Arithmetic” (LA) synthesis. This creative technique created a unique sound palette with lush pads, realistic textures, and distinctive digital timbres by fusing digitally synthesized sustains with sampled attack transients. In addition, it has a joystick for in-the-moment sound manipulation, built-in effects like chorus and reverb, and contributed to the sound of late 1980s music.
