This is a great freebie. Most of the presets sound like wind or string instruments. It is a very pleasant calm sounding synth, but you could probably get some more harsh sounds out of it too. More presets would be nice, but the ones provided are a good start. The interface is nice, clean and simple. If you know your way around, you'll figure it out in no time. Beginners should have a good time learning a bit about making sounds too.

I don't know if a good way to judge a new instrument is by how usable presets are that were created by using the randomization button are, but Padawan's are great. It came up with some nice wind sounds synths, to one that sounded like someone mumble-singing in the shower to someone making gun sounds with their mouth.

So if you are looking for nice, airy pads, download Padawna. This is another great, usefull product from Tweakbench.
