And without even using a single plug-in...
win 7 64bits, 16 Gb DDR3, 4 Raptor HDDs @ 10,000 rpm, one i7-920 @ 3.2G
3 delta 1010 soundcards
edit: I corrected the Sonar parameters, buffersizehdd ... and as a consequence it now works only in asio, no wdm for me, it's a pity since it has less latency with wdm than with asio
But it works
All in all, it's not bad, we'll see how it responds in terms of reliability and, especially, stability
I'll keep on testing it
