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. Read more about Korg 03R/W ai2 Synth Module
This is a set of MIDI files that can be used to make a Roland GS device emulate an Roland MT-32 (some better than others). This is similar to the MT-32 to GM MIDI files, only this is GS to MT-32. The Roland GS device in question must contain the original Roland MT-32 tones in order for this to work. There is also a MIDI file to reset the device back to the standard Roland GS settings. This file is a self-extracting Pkzip file.
Roland MT-32 to GM General MIDI Conversion MIDI Files
The Roland MT-32 was developed and sold well before the time of General MIDI. This is a set of MIDI files to set the Roland MT-32 and MT-32 compatible modules to patch sets that more closely emulate the General MIDI specification. There are a few MIDI files included here that only work with the CM-32L, CM-64 and the LAPC-I. There is also a set of MIDI files to set the Roland "D" series synths (D-5, D-10, D-50 and so on) into GM mode. This is a self-extracting DOS Pkzip file.

This seems to be the same Roland serial MIDI driver that came with the MPU-401, but it works just fine for the SCC-1 considering that the SCC-1 is a true MPU-401 compatible MIDI interface (meaning it actually supports both UART mode and the normal “intelligent ” mode).
I would say that the House of Synth is indeed a great place to get your vintage synthesizers from...I would recommend it even for my mother in law :) Thank for giving me the opportunity to get such a great piece of machinery!!!
