hi, i'm using acid and ez drummer, when i preview the grooves the sound is terrible, juddery distorted etc but when i drag n drop into the track it plays back fine (dropping out occasionally)
im using vista & apparently it supports boths progs, ive only got 1gig of ram, could this be the problem? or maybe the onboard soundcard?

i only want to use it for drums as i will record guitar bass etc direct into a digital porta studio

any help would be appreciated

thanks in advance
