I got a MacBook Pro yesterday - 2.2ghz, 4GB RAM, 200GB 7200rpm HD.

I've been using Logic Mainstage (1.0.2) with it, and I've found that a buffer of 128 is an ABSOLUTE minimum, so that I don't get constant dropouts/clicks. Ideally, it needs to be set to 256, but the latency isn't too good from there upwards, so I'm trying to keep it to 128 if at all possible.

But, I've only been doing 2 instruments layered - piano, strings, with a couple of plugins on each, and I have to be very careful how many notes I sustain etc., for fear of dropouts. The CPU meter is constantly above halfway even with simple playing, and often approaches 80%+. I'm having to watch the CPU meter all the time and watching the notes I play/sustain - not good!

Also, I loaded a Yamaha piano sample (included with Logic Studio) into the Explore/Instruments top piano, to replace the Bosendorfer (which plays fine at a medium buffer level), but the Yamaha refuses to play at all, even on the highest (unplayable) buffer setting. It stutters like crazy.

As my machine is high spec (full 4GB RAM, 7200rpm HD, 2.2ghz Intel Core 2 Duo), can someone please help me to optimize everything so that I'm not playing live with terrible latency, and so that I don't have to watch what I'm playing (and watch the CPU meter) all the time. Surely I should have enough power for just a standard set using Mainstage (just a couple of layered sounds at any one time - I'm not talking 20 instances of Sculpture here!).

Thanks for any help and advice anyone can give me.
