I almost forgot to mention...
Out of a lotta chips the tracker has, well, so far right now, I do notice key chips not in yet, the Sega 32X's sound chip, the SH-2, that adds 2 additional DAC channels, heard from Knuckles' Chaotix's songs via videos, and, of course, the Sega Saturn's sound chip, the SCSP, A.K.A., the YMF292, which has 32 sound channels that can be used in either FM synthesis, kinda said to be stronger and more advanced than prior key FM sound chips, by comparison, or by PCM digital audio recording and conversion.
I felt very awful the two systems launched too close to each others' dates, the 32X in the US, and the Saturn's launch in JP a day later, and because of it, the 32X's lifespan's been unfortunately cut short, and that hindered its potential a lot, being an add-on for the Genesis, and not even the greater potential with it plugged in to the Sega CD.
I wonder how much better Sonic 3's both halves would've been as one whole 32X game alongside the original split into 2 16-Meg carts, the latter's second half having its lock-on cart built in?
I could imagine seeing enhanced graphics by the 32X's capabilities, such as having one additional layer for backgrounds in pretty much every Zone in there, as the cases with Spider-Man: Web of Fire and the cancelled 32X version of Disney's Pinnochio(which looked better compared to the Genesis' version, just only saying), and lots more on-screen sprites, and much bigger sprites that could've been for bosses, even for the Kyodai Eggman Robo, the game's final boss at Death Egg Act 2 after the penultimate and final major boss, Death Ball.(Note: It still counts as a MAJOR boss, NOT a mini-boss. I can tell because it played the major boss music in all prior Zones)
If anyone could even conceive a 32X enhanced port of Sonic 3's both halves into one game that actually uses the 32X's capabilities one day, well, I'd be greatly elated to see it come to reality.
But enough of it. Moving on...
I could presume the YMF292's FM sounds were recorded and compressed into the PCM's audio channels, because even though the FM sound pallet sounds a lot more beautiful to hear, as the cases for sounds heard from Sonic R and Sonic 3D Blast's Saturn port, they're not completely heard crystal clear, as in, straight from the chip's FM channels themselves. A good guess, from my perspective and small insight, the latter's sounds were used as a soundfont of its own, rather than the chip's FM channels.
Of course, to better hear how those sounds were, I do have YouTube video links about them here...

Some sounded rather less stellar, but others sound like they're better enhanced by the chip itself, example being the Continue sound effect sounding a lot more beautiful than before.
You could tell the difference from those recorded into the Saturn's PCM channels, and from the Genesis' channels' crisp and clear audio themselves via your ears.
I would REALLY love to see and have those chips added to Furnace. All that potential those chips still have, are still regarded, ignored, and taken for granted by a lotta people lately, as with loads of sound chips before that tracker's launch. If anyone could take the time to talk to TildeArrow about that, well, it would really help to add to the tracker's ever-growing collection.
