Just did a 2.5 hour set on Friday with the new 1111 update on OSX10.3.5. I've got a 12" powerbook with 786mg of ram.

Man, I gotta hand it to you guys/gals at Serato..... you really came through on this one. I didn't check the precise drift fix by doing the same track mapping to both decks, but after using it to record my 2.5 hour set in a completely controled recording situation, I had no trouble with beatmatching what so ever. A+++ in my book, you finally achieve what Stanton and NI couldn't, from the bottom of my heart, thank you!!!!!! I can finally use this nifty software to record my dj mixed CDs!!!!
