Hi Andrew,

You have to understand that a full orchestra score such as you describe will be extremely demanding no matter what solution you choose. With a dual G5, you have plenty of processing power, now you just need to add more RAM -- I would say 2 GB at minimum, but more is better.

I am able to get decent playback of a full orchestral score similar to the one you describe on my 1.42 Mac mini with only 1 GB of RAM if I do the following:

1) Scale back the polyphony on certain instruments, especially the percussion. Cymbal and timpani rolls will kill you unless you limit the polyphony.

2) Turn off the reverb.

3) Lower the sample rate.

4) Turn off scrolling playback.

5) Don't try to run anything other than Finale, iKey, and GPO Studio.

6) If worst comes to worst, you can always record one orchestral section at a time (winds, brass, perc, strings) then combine them in a multitrack audio editor.

Also keep in mind that allegedly significant performance tweaks for Mac from Native Instruments *are* in the pipeline.

Although I can't say I wasn't disappointed with GPO's shoddy Mac performance at first, I've learned to be patient and, for now, work around its limitations. It's still worlds better than Finale's SoftSynth output, and I don't at all regret the price I paid for it (much higher than the group buy price!). YMMV, of course, but it's simply not accurate to say that a dual 2.0 GHz G5 with 2 GB of RAM can only handle 10-12 GPO instruments.

Those of us on Macs are hoping that a new version of Kontakt Player

Yipes! And I have one gig of memory in my new 2.0 gig dual processor Mac. Does that mean if I upgraded to two gigs that I'll get 10 to 12 instruments? How generous! (read with extreme sarcasm). I'm starting a score with triple woodwinds, full brass, percussion and strings. I was hoping to buy Garritan but it seems ridiculous to even try with these limitations. I'm still tempted to buy GPO while the price is low, but it seems a dicey proposition since I wouldn't be able to use it very much.

Darcy, thanks for the notes on *channel* changes to get pizz. I told my friend and he says it works like a charm.
