I ended up buying cheap ($10) MIDI USB cables and they work perfectly fine.  The only other thing I used the WaveCenter card for was SPDIF for my Pod Pro, but since that also has line out, I just connect it to my main audio card.

Mandremo, did you ever get the WaveCenter PCI card working correctly with 64-bit Windows 7?  Or does it still blue-screen when you try to shut down?

Eric, did you ever get the WaveCenter PCI card to work correctly with 64-bit Windows 7?

Has anyone gotten the WaveCenter PCI card to work correctly with 64-bit Windows 7?

Or is it still buggy?
