I have been using it for years.
It is the standard by which I judge all other softsynths.
It is easy to use, has quick right-click midi learn for all moduals and sounds great.
Additionally [thankfully] it has presets for classic synths like the SH-101, moogs, etc.
I have to admit I usually just use the presets since it is daunting to start from scratch with a modular setup and there is no limit to what you can do eighter.
I don't have the latest version. They made it nicer looking and added a few moduals but still the same.
