I use ableton live on a notebook acer travelmate2700 (pentium 4 3gb-512 mb ram) with a sound-card bca2000 of behringer.
in ableton use a channel audio for the base and another for the voice with fx in real-time.
the files wavs of the bases are of 40\50 mb and at times I feel some micro interruptions!!!, I have read on the manual that exists the function ram that directly loads the file in the ram,
does this resolve the problem?, have you had similar problems?
excuse me my bad English
