I finally have my recordings ready! Sorry for this late, huge submission:
Edit: I updated the links due to an unexpected/unset time limit noticed by me 2024-08-01. Now I have the SC-88Pro and SC-D70 too, so I'll try to include them sometime.

First, any recordings with "MIDI" in the filename denote use of actual 5-pin MIDI input when USB virtual MIDI would have been possible. Since the 5-pin MIDI connector should be all I used, the addition to the name was to be sure it was obvious, on those devices that had a choice. That was done to avoid ground loop noise in most cases, and in the digital audio cases, just because it was already connected for the prior analog recordings. Everything without the "MIDI" naming only has the 5-pin MIDI input, so you shouldn't be under the false impression that I had used another method of connection.
The only recordings I have not done at 96kHz are 44100Hz for the MU2000 EX from its SPDIF toslink (because that's its required rate) to the UA-4FX with its optical input. Those files are named with "44100Hz" to make them obvious. On the topic of the MU2000 EX, I set its UTIL->SYS->DigiOutGain to "+12". It doesn't clip with that and improves the dynamic range. I chose only to record it with the UTIL->SYS->Map set to "MU100Native", but doubt there's a difference for its GS sounds. I could be wrong about that, though. If you want two more sets of recordings (analog and digital), or another six songs, I will record them for you upon request.
The SC-8850 recordings all used the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu, since it's normally always connected there. I had tried other inputs on the STUDIO-CAPTURE, as well as on the UA-4FX because the SC-8850 MAP recording of Elise always showed significant 180-degree off-axis piano sounds between the right and left channels. That leads me to believe Roland purposefully used that to create the stereo piano effect, so I eventually gave up and sent you a recording from the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu for the SC-8850 MAP too. The SC-8850's other MAPs only had reinforcing waves for the Elise piano.
The SC-8820 recordings all used the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu.
The analog MU2000 EX recordings all used the STUDIO-CAPTURE inputs 15 & 16 attenuated at -10dBu, since it's always connected there.
The analog INTEGRA-7 recordings all used the STUDIO-CAPTURE inputs 5 & 6 with SENS set to 5.5dB, since it's always connected there.
The INTEGRA-7 USB Digital Audio recordings (named with "USB-DA") were done at 96kHz, though MIDI was played through its real MIDI input (due to already having been setup for the cleanest possible analog recording). I did an additional three songs, in which I hoped to show you what my patched QMIDIRoute with the INTEGRA-7 SuperNATURAL remapping qmr file will do, although they aren't what your after as they're basically realtime-edited versions of your files. These extras are USB Digital Audio recordings of the INTEGRA-7 with "QMIDIRoute" in their filenames. EDIT: Here's a link to the INTEGRA-7 MIDI files created by sequencing QMIDIRoute's output for your examination: https://1drv.ms/f/c/0ea455a97f6b04c3/EsMEa3-p … 01kaTw?e=ReV6tk
The SC-33 recordings all used the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu.
The SC-55mkII recordings all used the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu.
The PMA-5 recordings all used the STUDIO-CAPTURE inputs 13 & 14 attenuated at -10dBu. For them, I also turned on "MIDI Update" on the PMA-5's UI, just in case something wouldn't be set otherwise. For the "Batteries" recordings I used six Panasonic Eneloop AA batteries, and for the recordings without the name "Batteries", I used the BOSS R3W009-200 PSU it came with.
The SCP-55 recordings all used the STUDIO-CAPTURE inputs 1 & 2 with SENS set to 20dB. At first, in pure DOS I attempted GSPlay, but it had timing discrepancies, so I eventually installed it on a windows laptop. That allowed me to use my consistently-timed Linux MIDI player (audacious) by connecting the MCB-3's MIDI IN to the SCP-55 Synth virtually with midiOX. The MIDI IN is probably only intended for sequencing otherwise. The MCB-3's Phones output from DOS (with no mixer software) is quieter than all other modules turned up to max, and with windows 98 it's still quieter, but I was able to adjust volumes. A difficulty with the volume set too high in windows is obvious internal clipping. To work around that, I set "Playback" volume for "Synthesizer" to about 2/3 up with main "Volume" at max, and the "MIDI" screen's "MIDI Volume, "Chorus", and "Reverb" each at max. The other MCB-3 audio inputs were muted. It didn't make much difference, but I recorded using the laptop's charger connected (named "Laptop-PSU"), and then without that and only the laptop's battery power (named "Laptop-Battery").
The CM-500 recordings all used the STUDIO-CAPTURE inputs 1 & 2 with SENS set to 10.5dB, and the CM-500 was set to Mode "C", for GS ("CM-300") of course.
