The XW-G1 is quite different from using an XW-P1. It is more to create rhythms and sounds more easily. But to be "perfect" it would have to be analog modeling. I needed to buy a Novation Mininova and, in the future, a Studiologic Sledge because the XW lack this feature. Now that I understand the theory of synthesis and the characteristics of the XW-G1, it is indispensable for my creations. The XW-G1 is rare comparing it to the XW-P1 and other synthesizers because it is a groove synthesizer. It's great for experimenting and creating electronic beats. The XW-P1 is more "conventional".
NOTE: I explain under my "style" of musical creation.
