No, but it depends on the amount of memory on board. Does your Max have the full 1MB? If not, Doom maps its music to use less instruments.
Maxing out Max' memory is rather easy though - you just need a single 512kB SOJ chip from something like a PCI S3 VGA.

(And OPL emulation will always be awkward on GUS, sad but true.)

ah what a bad luck
i got a box full of trident,s3 virge, and cirrus logic vgas
and.they all got 256k chips

can you shoot me a link from ebay? i tried searching 512 soj and there are diferent ones say dinamic and other saystatic

If it says something like 514256 or something similar and it fits, you're fine. These are 256k*16bit chips AFAIK. Many 1->2MB cards have two soldered plus two sockets of them.

Like this:

514256 would be 128 kbytes, since it's 4 bit x 256k. You need to look for a chip that says xx16256.

e.g. this one: https://www.ebay.de/itm/323005054065

I see where you're going and I can only hope I didn't mislead Pabloz but there's a Macronix card in my hand, has a pair of 514256s and a pair of 514260s, and reports 2MiB.
This other S3 Trio64 from the same drawer has four soldered 514260s, reports 2MiB. And AFAIK there's no PCI 512k S3 Trio64 (what it would be if the chips were indeed 128k ones).
And they work in high res modes that need much more than 512kiB RAM. I'm not a big fan of these chip markings.

Judging from this pic from the amoretro.de website http://www.amoretro.de/2012/06/gravis-ultraso … ax-rev-1-8.html

One needs a AS4C256K16 DRAM IC to reach 1MB and they are available on ebay for 8GBP here: https://www.ebay.co.uk/itm/282819934730 , that's what I would get

All pics I see on the web of MAX cards use 256kbyte/16bit DRAM chips so this means that the card is using them in 8bit mode so the capacity doubles at 512kbyte. That's my take on it.

SEARCHED EVERYWHERE...this is what i found so far, per your comment the second one in the list should work? but says 256k edo

each videocard that had memory sockets and this is what i found:

diamond stealth2000 - OKI M5416258A-3J
trident - 516256J04SM6 EDO040604DEE
trident - siemens HYB514175BJ-60

I have this very chip in my GUS Max v2.1.

awesome!!!

THANK YOU, I just installed one of those on my gravis and now sounds are much better, i hear the drums, the flute with the imp song.

how to you recognize in DOS if the 1mb was installed? is there a command or just by hearing as it detects it automatically on gameplay

My favorite easy way is to start Impulse Tracker. It detects the sound card, including its memory and displays it right on the splash screen.

But the GUS driver pack's (that you downloaded) setup.exe can even test it.

The GUS is always a difficult card to get going... Especially a MAX due to the increased resource utilization. Common practice is to remove all other devices, set the GUS up to use as few resources as possible. Recording and playback can share DMAs (and I think IRQs) if you don't intend to record on the card. Once you've got it going, put other cards back in and configure as necessary.

yes either use the driver's setup to test for ram or see if the attached GUSDRAM program works for the MAX - it tests the ram fine on my Classic card

Detects 1 MB just fine on my GUS MAX 2.1
