I've never posted any tunes here, but I've had GPO for more than a year now and I figured I may as well take a deep breath and hop in.
Here are a few tracks I've done lately that make heavy use of GPO:
Parergon Theme: http://www.willowtreeaudio.com/media/Parergon.mp3
This for an isometric PC RPG from Games for Insects. Strings are GPO, the rest of the orchestral stuff (toy glockenspiel, bass drum) is free G-Town samples. The synth stuff comes from Reaktor 4, Absynth 2 and hardware (*GASP*)...Triton, XV-5080 and XP-50.
This one was whippped up for the GANG composition contest. It's a little truncated because of the maximum entry length of 1:05. Again, GPO strings and some brass. The horns are layered with Edirol Orchestral horns because I didn't have enough time to figure out how to make the GPO horns sound ridiculously big by themselves. The snare is a SAM freebie. Synth stuff is Absynth 2 and the same hardware as above.
Needless to say, I love me some GPO strings.
Enjoy...feedback is appreciated.
