Is there a way to disable the fake Adlib emulation with SBOS? It really sounds like butts. Like, out of tune butts. I know the ACE has a jumper of sorts that allows disabling it, but I'm wondering if there's a mod or something that could disable this on a Classic card too since both cards share the same GF1 chip.

My suggestion is to not use SBOS . Use another sound card that actually has hardware Sound Blaster compatibility along with your Gravis . IMHO, life is too short to waste with SBOS, if you have the choice (same goes for Mega-Em's Sound Blaster emulation).

As for jumpers :

Second that. Back in the day I even gave up on them entirely when I didn't have any other card available (and couldn't afford one either). At least the PC speaker worked...

Any decent SBPro2 clone would work fine next to the GUS - an ESS688 or ESS1868 would be entirely appropriate as that's basically making a two-card GUS Extreme 😉

Just make sure the GUS isn't on 220/7 (or 5)/1 and that the "SBPro2" is and you're good to go. Only question is which one does the (General) MIDI.

Those JP2 jumpers aren't on my card. I found that document once but it didn't match up with the one I have. JP2 is part of the expansion card's header.

These are the extra jumpers I was talking about:

The manual says nothing. 😖

The address jumper is down below. It's JP1. For shutting off the Gameport I use a parameter when initializing the GUS (ultrinit.exe -dj)

@the suggestions to get a real card instead of SBOS: Yea SBOS is probably a bad idea, but I wanted to try it out anyways. I was impressed that MegaEm didn't use a TSR, but it only does original SB Mono. Still pretty cool though! And it doesn't do a poor imitation of Adlib either (it doesn't try to emulate it at all, so you can pair it with a real Adlib). The MT-32 soundfont was neat on games that didn't rely on new instruments through Sysex commands.

But yea, getting a second card is absolutely in the plans. I'd probably use the second card for the gameport and MIDI to be honest. Thanks for the suggestions!

So far I'm liking it, but it's definitely an overrated card. I wouldn't recommend people paying the going price of auction sites for one. Jazz Jackrabbit and the other Epic Megagames games written to take advantage of the card do sound amazing though...!!
