Thanks, DslSynth. It's funny - I actually don't like the first piece. I think it's a lousy improvisation, but I posted it anyway as a demonstration of a sound. It's actually a difficult sound to work with. Because of the release time, the eight voices are used up quickly, which results in very unappealing pops as notes are re-assigned. This patch is a good argument for twelve or even sixteen voices. It certainly made me think of the Prophet 12.
Regarding the second piece - it's so easy to achieve the melancholic. Whereas, joy requires such an effort, as if you're fighting all the elements to get there.
