Korg’s 01/W workstation synthesizer debuted in 1991 as the follow-up to the popular M1. The O1/W was the second chapter in Korg’s workstation legacy. The O1/W was geared towards beginning home studio enthusiasts that wanted to take a step further into a more professional realm. Compared with the M1, the 01/W featured many enhancements including a more dynamic 16-track sequencer (the M1 only had 8-tracks), 254 real world sampled instruments to the M1’s 100, polyphony was doubled from 16 to 32 voices, and greater overall control.
