The Doepfer A196 PLL is one of my favourite modules. Unpredictable as hell. But once you find a way to tame it, it can really sound awesome. In this case it generates some kind of overtones that resemble a bowed string instrument in my opinion. I also like to use odd measures, should do that more often.
This post is pre dated. One of the purposes of this website is to put all my musical productions into one place. In order to get my archive more or less accurate, I chose to date stuff that was produced before the launch of this website at or around the time they were originally published.
