Hi Rik,
I just want to confirm, you have the Motu 828mk3, and it works with Windows XP. Have you got it to work with Windows 7 yet?
You have discreet channel control?
AND have you tried playing 5.1 audio files (muxed to a stereo audio file) and had the Motu unit split all of the audio signals out to 6 discreet channels?
(or am I misunderstanding how this is supposed to work)
If anyone else has these answers, that would be great too! I am just about to go and buy one.
Thank you,
J
