Hello, my friend Lumiere Eleve (https://hooves.social/@lumiere) is a MIDI developer who has made reproducible MIDI's of the Chex Quest 3 OST (all 19 tracks made reproducible with the exceptions of E3_M2) along with SC-88 renders.
The full renders can be listened to on Youtube:

And can be downloaded on their Mastodon (https://hooves.social/notes/agm0lpbzvbfd0aqn) in lossless WAVPACK or lossy OPUS/OGG
Visualizations of the reproducible renders are also slowly being rolled out on their channel:

All reproducible MIDIs can be downloaded here (https://drive.google.com/file/d/1Z6si0vzpH5pLnIjKQ6NXu23DBnVhuM16/view?usp=sharing)
The tracks were rendered in Octavia Cambiare (https://github.com/ltgcgo/octavia/), also developed by them.
These are listed as collaborations between me and them, but my part was only in bringing the tracks to their attention and ripping them from the original game.
In my opinion these are the best renders of the soundtrack I could find online by far, official or fan render.
I hope you enjoy them!
