The KORG 01/W FD Keyboard is a potent 61-key workstation synth from the early 1990s, displayed in a sleek black finish. It has an improved AI² synthesis engine with more waveforms, effects, and polyphony, building on the success of the M1. The 01/W FD was a popular studio instrument for pop, R&B, and electronic music because of its rich pads, changing textures, and adaptable sounds.
