Hey,
Yeah, Macs and PCs both do the same thing, they crunch numbers. The current Mac is supposed to be super fast, but a PC will overtake it eventually....then Mac will overtake the PC, and the PC will overtake the Mac etc. One is not inherantly better than the other. They both steal (or 'license', if you want to be politically correct) stuff from other companies and each other, they both have good and bad software, and they both can be used to download porn.
MOTU are notorious for making great professional stuff that runs lika a champ on the Macintosh, then to earn a few more bucks they write half-assed PC drivers and market it to Windows users.
Just go to their website...you can see Macintosh ALL OVER THE PLACE: Digital Performer, Unisyn, Mach 5 (Mac-only apps), links to Apple's site, information about compatibility with OSX.x, G5 compatibility, articles about famous Mac/Motu users, etc.
Please don't misunderstand me, I'm not pissed off at Motu for being Mac advocates; if I were to get a card for a Mac, they would be the first people I would go to. My beef is that they market these great products as being compatible with Windows, and this is simply not the case. People see all this wonderful hardware, the little WDM or XP logo at the bottom of the box, and buy it not knowing that they have a potential disaster on their hands.
At my last job I had to play with two Motu products: the 828mkI and an older 2408 with with 324 card. Some of our computers wouldn't boot with the 324, and the 828 wouldn't allow us to monitor anything through the headphone port. The Cuemix software crashed all the time when you tried to change settings, like what port to sync to or using the 'legacy mode' for non-WDM software...we wrote emails and called Motu all the time trying to figure out what was wrong, we didn't once get someone on the phone or an email reply.
If you get your 828 to work on your PC, I tip my hat to you in congratulations...
Good luck!
Nick
