So, about those other SB compatible cards. Where do you get your information on those? I went down some rabbit holes with some of those... the Yamaha cards look good... That one you linked looks legit too. I looked at some of them and found the Yamaha chip, but some don't seem to have it? I could just be missing it. Do you think any of them are better than a real SB 16? I want max compatibility. I kinda stopped looking at those because I don't want to deal with any edge cases...
I too, went down the rabbit hole after buying a ViBRA 16, not knowing that the real value is in the SB16 cards containing the Yamaha OPL chip.
As for the cards that "don't" seem to have it, I'll clear this up. When Creative first released the SB16 the OPL synthesiser was a standalone chip Creative obtained from Yamaha. At the beginning of 1993, they began integrating the YMF-262 FM chip into their CT1747 sound processor for their "Value Edition" SB16 cards, and the CT1747 chip doesn't have Yamaha's "OPL" logo on it; possibly due to Creative at that time who have yet obtain the rights to use the logo. However, that card does have a real OPL FM synth built into but no longer as a standalone chip.
Creative continued to use the OPL synth on their soundcards, including on their earlier AWE32 soundcards, right up until 1995 when they released their own, cut-down FM synthesiser called the CQM, which tries to emulate the samples the Yamaha OPL uses. But overall, Creative's implantation was not great. Reason they took the shortcut then was competition in the sound card market was getting tough, and attributed to this, costs.
Also, something worth mentioning if you are thinking of getting an AWE32 soundcard. Creative did released a SB32 sound card, and the most important part here is this is not to be confused with the AWE32. The SB32 is a significantly cut down AWE32 that would begin the cheaper ViBRA line-up, all containing Creative's CQM FM synth, which some
true AWE32 soundcards does have too.
While this may sound bad for us, there is a good news in choosing the right card. To tell if the card (SB16 or AWE32) does have Creative's CQM chip, look for the chip that says "CT1978" anywhere. This will be the CQM chip and that's the one you should be avoiding if you want the best quality. Regarding the "hanging notes" MIDI bug, cards with DSP v4.04, 4.05 (like yours), and 4.16 has no bug, including the cards with a CT1747 DSP chip.
Lastly, if you are interested in it, the AWE64 range. They all don't have the OPL FM synth, but even that alone still doesn't undermine how good the AWE64 sounds, compared to the AWE32. All of the AWE64 cards also has no "hanging notes" MIDI bug.
Where I got my info on all of this?

- Wikipedia also has some relevant details on the Soundblaster cards that may not have been covered elsewhere. They also have an audio clip comparing the OPL-3 vs CQM.
- Vogons also have some good discussions going on, although I try to avoid a lot of the drama that pops up anywhere in any thread, lol
- https://theretroweb.com/ - It's like a Wiki for old computing related stuff, including obscure hardware
Additionally, this comparison video went as far as including ESS' own FM synth, which actually sounds excellent, like Yamaha's.
Looking at the card you just bought, that looks extremely similar to mine, with the hardware volume dial at the expansion slot, lol. Mine is just a pinch newer with a different model number, made in 1993, and unfortunately, possibly a CT1741 DSP. Haven't tested mine just yet, due to the motherboard I am going to use is still missing a CPU; need to find a Coppermine, Mendocino, or Coppermine-T CPUs, which is not easy where I live.
