Ok im using ME 2.1.0 with Serato 2.4.2 with a MacBook Pro OS X 10.6.8, 4 Gigs Ram, 500GB HD that spins at 7200 RPM. The problem is the Waveforms are very shaky and bouncy they dont run smooth, makes me feel like Serato is going to crash, I even am zoomed out of the waves to make the waves run a little slower and smoother but still im noticing it! In ME i have my cache down to like 400MB & im running my output monitor at 1280 x 720 so i have my quality slider down to like 60% i believe or 70% im not sure cuz I cant verify at this time! Its not just this version of ME that i get shaky waveforms i also got them in 2.0.2 & 1.7.2 What do i need to do or check? When i run Serato & ME nothing else is running on my mac. I have airport turned off i dont use Bluetooth, what else can i do??? If anyone can help me out i would highly appreciate it! Thanks! DJ Ricky Lee
