Logic cannot play a full song without error of the demo content provided.

Question

I have airport turned off. No programs open, have had fresh defrag and cache cleanout. Logic is on my actual hard drive wich is a 320 gb western digital scorpio black 7200. I am using an apogee duet.
settings;
device duet
1/0 buffer 256
safety buffer on
recording delay -58 samples
universal track mode on
24 bit rec on
soft monitoring on
independent monitoring level on
process buffer range = small
scrub speed= normal
scrub response = normal
the track im playing ( to see how logic reacts as it has been poor in a few of my personal recordings - is the roots track 'marathon man' (stereo)
logic will just stop at third bar with an error message stating ' Disk is too slow or System Overload.
(-10010) '
this is a message i see so many times even in my own tracks. how can i overcome this premature stopping of audio flow? is it my computer specs, the specs in logic? im not sure. Does anyone know how to get my Logic 8 perforing at its peak?

Answer 1

Safety buffer must be off - on is probably only useful on G4 systems. On faster machines it can ruin performance. Also: Software Monitoring takes a lot more CPU than the more used & useful (hardly any to no latency) Direct (Interface) monitoring.
