you mean that it currently has 512kb chip installed on it? So 512kb ram.
I had put some extra 512kb 256k x 16bit fpm soj chip and run ok on 1mb, but did not notice any difference on midi, i could be wrong.

No. It has only 256k. Only 2 dip sockets are populated.

Check out this thread carlostex. fantasma had a similar problem with his GUS Classic, and the only solution was to upgrade the GUS RAM to 1meg.

Awesome. I just read through that threah and the problem seems to be the same as mine. Plus i also tried playing MIDI files that come with the drivers, and like with fantasma there are no problems. But with games it's a different problem.

Yeah, I had the exact same symptoms, it sure is a RAM issue. If you can't find anyone that sells those memory chips, I think that you can get them from some ISA video cards.

PS: I also have the CMI 8330, that's a good card too!

Yeah, you really need 512k minimum. 1Mb is best, then you can load the propats instrument samples without losing any sounds (they're higher quality and take up more sample ram).

Now some games seem to have missing instruments. Doom and Duke Nukem 3D seem to be missing the snare and cymbals. The digital part of the card is fine and plays .MOD files just great. It seems that only the wavetable stuff has some kind of trouble.

Actually, the 'digital' part is the 'wavetable stuff'. The GUS has 32 channels, 2 of which it normally uses for digital audio, but there's nothing really special about those hardware channels compared to those it normally uses for music. Normally with a MOD player you'll have 4, 8 or even 16 of those channels all playing from the GUS, in hardware via the onboard ram and GF1 chip, rather than being mixed in software on the cpu and output as a merged digital stream (such as on a SB16). It's quite neat, shame it never really caught on that well.

Hope you can pick up some extra memory to hear it at its best!

768Kb of RAM upgrade are on their way!
