The MIDIMAN cards work okay. I have a DMAN 2044 that I have used with GS. Their drivers have some glitches in them that require work-arounds sometimes. In my case, whenever I rebooted the machine, GS would not output sound through the MIDIMAN card unless I initialized the driver with another program first. You also sometimes get crackling noises on output (this didn\'t have anything to do with the hard drive speed -- I have U2W SCSI drives). Overall, the MIDIMAN products are a bargain if you can live with the glitches. I couldn\'t, which is why I bought my Aark 20/20.
I used to use the DMAN PCI - not bad, not great - y\'know, you get what you pay for ...
It\'s a little soft on volume - I don\'t %100 trust the drivers - that\'s why I switched, plus, although pretty good, the sound wasn\'t quite what I was looking for. I originally bought it because my other SC wasn\'t \'giga compatible\' and I needed a decent, (yet cheap 8-) DirectX SC for Giga
