Hello

I just bought a MacBookPro 15" to use with my MADIface. The problem is I cannot record 64 channels at the same time. I use the card to record all channels from a Soundcraft Vi6 mixer using its madi output. I have to reduce the channels to less than 60 for Nuendo to be able to record. If I arm all 64 tracks i can only record for about 5 sec before nuendo shows an error message (to many tracks recording). Even at 60 tracks it is not totally stabile. I have to go below 56 tracks to be safe. At 60 tracks I get an 88% cpu usage.

I suspected this to be an OSX issue, as the task was no problem for my 2 years old Dell laptop... I installed WinXP SP3 on the Mac and I can now record all 64 channels without any problem. The machine is also a lot more responsive under Windows. All tracks recording I get an 30% cpu usage.

Another concern is that the expresscard gets very hot!! is this normal/safe?

best regards
