alexbogran on Extreme glitches on Ezmix 2

So i Just bought ezmix 2 and the metal bundle as well as the ambient guitar packs and some strange reason, i keep getting really really bad delay and or loud audible glitches. Some don't glitch as much but, other are almost impossible to play. I'm running my guitar through a scarlet2i2 and i'm using my PC laptop. I've tried to increase the latency over and over, and i even tried to download an other ASIO driver, but still no luck. its very strange. also my computer Usage spikes every time i open one one of your programs. but i only get glitches through ezmix i have no trouble with ezdrummer.
id appreciate some help!
