That is a link to one of my tracks. Selfless shameless promotion LOL
But in all seriousness, the XS is a beast. If you read the replies you can tell what all I used, and I happen to use a pro1 and a XS in the same track. I use the XS in a significant amount of my tracks. It does crunchy/gritty bass extremely well, as well a decent lead type sound.
If you are wondering whether or not you think it's a good buy, the answer would be yes. For what it's worth, I rarely use it for the semi-modular capacity. It's cool that it can do that, but meh, not needed really.
