Korg launched the O1/W series of workstation synthesizers in 1991 as the successor to the M1 and T series. In addition to the O1/W, which was only available until 1994, the 01/W FD, the O1/W PRO, the O1/W PRO X and the rack versions O1R/W, O3R/W and O5R/W were also available. The technology is based on AI2 (Advanced Integrated Squared), an improved version of the AI (Advanced Integrated) synthesis technology found in the M1. The sound generation is almost identical, but 16/32-voice instead of 8/16-voice, and there are more samples in the 6 MB ROM, including 254 different vibration shapes/multisamples and 118 drum sounds. The instruments also have two effect processors and a built-in sequencer.

The O1/Wpro workstation corresponds to the 01/W FD with a non-weighted 76-key keyboard. However, the sample memory has been expanded from 6 to 10 MB ROM. It therefore has 32 oscillators, which can be configured as 32-voice single sounds or 16-voice double sounds. Harmonies are added to the waveforms and resonance-like effects are achieved using a waveshaping envelope. Envelopes are available for the oscillator (OSC), waveshaping (WS), filter (VDF) and amplifier (VDA). The modulation options are extended by the LFOs and the play aids. There are two independent effect processors, each with 47 different algorithms, which create reverb and echo programs, chorus, exciter, enhancer, flanger, distortion, phaser, rotary speaker, equalizer and combination effects, 16-fold multi-timbrality, 200 sound programs and 200 program combinations with possible extensions.
