Nothing fancy, just a short 1.5 minute "let's see what GPO can do" demo that I did in the first 3 days of owning the software and looking through some of the tutorials.
A few different textures, a simple theme, and of course, some mallet percussion at the end. I'm a percussionist so I'm a fan of the marimba-- I might do an all percussion sequence next.
Software used: Sonar 4 Studio Edition
FX: just the ambience reverb
