i use cubase5.1 (32bit) , i5 processor, 6giga mem ,win 7 64bit .clean os . when certain projects open , ( indeed a lot of channels but the cpu is not at half its power ) and the asio time overload is crawling its way up …
btw , the same project , opend on muce simpler sound cards - worked great .
what could it be ? a messed up vst or maybe a not good enough fw card ? ( t.i chip but not top of the line )
