Korg 01/W keyboard synthesizer

Korg 01/W is series of workstation synthesizers manufactured by Korg. The first debuted in 1991, and were intended to replace the M1 and T series. The workstation/ROMpler was based on AI² (Advanced Integrated Squared), an improved version of the AI (Advanced Integrated) Synthesis technology found in the M1 (although the advancements of the core synthesis engine were arguably quite minor, except for the subsequently removed Waveshaping, see below). The success of the AI² architecture ensured it was used in the majority of subsequent Korg synths of the 1990s.
