My new (used) computer arrived so I can finally install GPO. (A real steal on eBay 3.2Ghz 1GB RAM, 200GB disk space, Soundblaster Audigy, all for 150 bucks US) The installation and registration went smoothly. Both Noteworthy Composer (my notation program of choice) and my stone-age Cakewalk 7 talk to Garritan Studio just fine, so everything is a go.
Now all my score files are still on the old computer so I have a lot of file moving to do before I can do any serious rendering. I did do a quick render of a Clementi Sonatina that I transcribed from piano to brass quintet, but as a first test render it's not ready for sharing until I do some more fiddling with cc1 in Noteworthy. At least I've established proof of concept that I can make cc1 envelopes in Noteworthy and have GPO pay attention to them, so it's all good.
Unfortunately, I'll be in San Fransisco for the weekend so it will be Tuesday before I get to dig into some serious GPO experimentation and learning sessions. I'll be back Tuesday with, hopefully, my first genuine GPO render.
