Korg's AI Synthesis on the Cheap
In the early 90s Korg wanted a synth that supported general MIDI and that could provide a cost effective intro into the same synthesis engine (or at least similar in this case) as their flagship 01/W synth. The Korg 03R/W synth module filled that void.
The AI squared synth engine in the 03R/W was not exactly the same as the 01/W and the two cannot share synth patches or sysex data. The 03R/W lacked the wave shaping functionality of the higher end 01/W line of synths.
