there was a post on this list that went into great detail about how , most of the time, the "cpu too slow" message could be traced to the logic audio device setup system creating erroneous configuration data. this data is refernced in the system folders (sorry about the registry thing, it wasn't the registry). what was causing mine to flip out was the device setup determining that my soundcard had more ins and outs than it really had and storing this info in the system folders. ifollowed the instructions in the post, corrected the info, and LAWP has worked quite well since, outside of the occasional error or two. if I can find that particular post again, I will definitely repost it. Onyxashanti > After reseting my virtual audio drivers in the registry, Logic worked like a dream. It screams on my laptop. I am able to play back about 26 audio tracks with no sync problems, and a few effects thrown in. the waveplayer is a godsend because it WORKS!! no latency, no crackling. yeah it could use some work, but it works...NOW! Midi is rock solid. I don't have to setup audio buffers every time I want to record. it is customizable to an extreme. Where did you get this information on reseting virtual audio drivers in the registry and/or what exactly did you do? Thanks, john
