Not that we would want to use GM.DLS if we had a choice, but still. I have a few variants of the CMI8738 and noticed that what the driver calls "C-Media MIDI Synthesis" is just a softsynth using the GM.DLS patchset. (I renamed it GS.BAK and ran DXDIAG, which did not play music until I renamed it back.)

Can all PCI sound cards access a softsynth that can use Microsoft's GM.DLS patchset? Or just the models that were specced for it? I notice that it sometimes shows up in the MIDI tab (under Multimedia) as an option but doesn't always.

The older VXD drivers have an OPL2 MIDI device and a Softsynth device that uses a 3 MB DLSWAVE.DAT, but I haven't tested it because the digital output stopped working on my CMI-8738. I have another CMI-8738 with digital but I won't be able to install it until the weekend.

PC1: Win98SE - Via Apollo Pro Mobo - Pentium II 233 - 256 MB - Voodoo 3 1000 - Acoustic Edge PSC706
PC2: Win98SE - ASRock 775i65G R3.0 - Celeron 2.2 GHz - 2048 MB - Geforce FX5700 - Audigy 2 ZS

That's interesting. My drivers are VxD, but nothing happens when I select FM synth in the DOS games, and there's no FM option under the MIDI tab. I'll have to find some older drivers if it's true that the CMI-8738 has an embedded OPL3.

Last VXD with FM Synth I could find: http://web.archive.org/web/20060117220544/htt … w9x191cfull.zip

WDM: Never used except for dogbert's unofficial CMI WDM driver http://code.google.com/p/cmediadrivers

Tried to see if there's any difference between VxD and WDM drivers?
