Logic Crashing, Too much audio? Options

[jen123456]

Hi boys,
Logic keeps crashing. I've got a G5 dual processor power mac. I'm trying to play a song that has lots of audio and plug ins etc. but everytime it crashes as soon as it starts playing. Have I got the settings wrong? I wasn't sure how I should have the buffer settings and whether I should be chaning these for recording and then again for playback? I've tried playing around with these but I'm not sure what I'm doing and if this is even what I should be doing? Just read another post...should I buy an external hard drive?

Any ideas?

Jen.

Ok I'm a bit of a computer idiot but here goes....

1) Which OS are you running;

Mac OS X 10.4.3 (8F46)
Kernel Version: Darwin 8.3.0

2) How much RAM do you have

2 x 1GB

3) What is your HD size and how much of it is abvailable?

Macintosh HD:
Capacity: 233.64 GB
Available: 108.69 GB

4) Which DP G5? Not sure about this, does this answer it?
Machine Name: Power Mac G5
Machine Model: PowerMac7,3
CPU Type: PowerPC G5 (3.0)
Number Of CPUs: 2
CPU Speed: 2.3 GHz
L2 Cache (per CPU): 512 KB
Memory: 2 GB
Bus Speed: 1.15 GHz

5) By crashing, do you mean that Logic is quitting or that it pops-up a dialog saying "too many... Continue"?

Yeah Logic shows and warning and says it must stop, there's no option to continue

6) Logic Express or Logic Pro. which version?
I've got Logic Pro 7 (I bought the 7.1 update but when I tried to install it it said that newer versions of the software were already installed so I didn't).

I've been using a Yamaha grand piano sample in my song and that seems to take ages to load up and save etc. 10 x longer than any of the audio....i wonder if that's the problem?

Thanks for your time and help. Jen

(Also someone suggested that I should look at the CPU info...do you know where that is?)
