I stumbled upon a super rare sound card on ebay the other day. It's some model from Crystalake, a company that is VERY hard to find info on.
I have been digging for hours looking for drivers. It's a Mad16 + CS4231 card and have managed to get it working for SBPro mode. But the Mad16 initialize doesn't seem to power up the MPU-401 at all and no MIDI plays. Does anyone know more about this combo of chips?
I can't even figure out what the jumper settings do so I haven't touched them. I hope it's on workable settings...
Under that printed Crystalake sticker I found the Opti 928 Mad16 chip.
