For me and my ambient taste this is by far the best Mirage library so far.
It really uses the options of the 3 soundsource library with great presets that get you instantly going.
I especially love that there has been really much work and thinking going into the preset naming, so far for me every preset simply sound like I would expect from the naming. That helps so much for finding the sound you are looking for.
Of course this is mainly about pad and drone ambient preset but the few plucks/rhythmic movements/textures are nice and usable too. Interesting that while all pads, athmos, drones and so on all go into one category "pads" there is a small extra texture section.
I have not even come close enough to look into the soundsources (which are not that much and divided again in an unusual way with air/mid/low/vocal) more in detail cause the presets are really capturing attention so far.
