You can do a lot of different sounds with it. In the beginning you will probably get those FM type sounds out of it, but when you start to understand it you can make sounds that aren’t sounding FM at all.
But you will need to spend many hours with it to grasp everything. That’s how it’s been for me at least. I have not grasped everything yet, but I’m getting there. The filter is an amazing feature that makes it even more versatile.
The best tip I can give you if you buy it is to get some good sound packs and learn from those sounds.
