Hello David.
I've just started using GPO with Finale and have heard the same crackles. One thing that seems to help is to have Finale on the screen and hide all other open applications, including GPO itself. Turning down the knob for "Quality" on the Abience plug-in helps as well. With larger Finale files it seems to help to run playback set to Non-scrolling.
It will be interesting to see what develops as more and more of us begin to use GPO.

Hello, I hope to tap some wisdom about dealing with Garritan Personal Orchestra. I just got it and have been fooling around with it. It is really fine -- better at orchestral instruments than Reason (which itself is rather good). And relatively easy to learn.
However, I am having some problems getting it to work without making crackling sounds, which, I suspect, are memory/processor issues.
I am on a Mac, using GPO within Digital Performer. It works rather well, by the way, within Finale, especially with the new version of Finale having an "optimize for GPO" setting (which reassigns some velocity/continuous control data). There are also some issues with GPO and its use of CC #64 for tenuto -- which means it can't be used for sustain on piano.
GPO recommends at least 1GB of RAM. I have 1.5 GB. They ask for a minimum of a G4 733 MHz processor. I have a G4 1.33 MHz.
GPO's stand alone player is rather useless for me, with only one instrument at a time, and no sequencing. Might be great for live playing, but I don't do that. But they offer a Digital Performer plug-in, and also a VST plugin, and a studio player for use within Finale.
For a few chamber situations I have tried it in, it works very well. I am working right now on something with saxophone, so I am using a good saxophone patch within Reason, and using GPO for the other two instruments (piano and bassoon), running the whole thing with Digital Performer. No problems.
To test GPO, though, I am trying to put into DP Beethoven's 3rd symphony (Scherzo). Unless I run it dry, without any reverb, I get processor/ram crackles. It doesn't fail, but it just makes awful crackling sounds during the fuller sections. I have checked some of the GPO forums, and I hear this is a problem even with faster G5s and 2GB+ of memory. I have tried some recommended tricks -- reducing polyphony, simplifying the orchestra. I have tried bypassing GPO's "ambience" plugin (nice sound, but seems to be a huge memory hog), using Apple's (inferior) AU reverb plugin instead. I also tried messing with DP's hardware configuration settings (these are very confusing to me, but I think I have good settings).
Are there any GPO-on-a-Mac experts out there who might be able to help me get more performance out of GPO right now, especially for orchestral things?
Maybe we Mac folks need to wait until we can all have 2-3 MHz dual processor G5s with 3-4 GB of RAM? Or hope that GPO comes up with a better way of managing its demands, especially on a Mac?
Any help would be greatly appreciated.
