Oh yeah! I saw seb do some of that on 3 of his ambient tracks and I've decided to try that out and it worked perfectly, it took some experimenting though with the
Pulverisateur and Heisenberg but after 1 week I got them both to work out. Plus the curve is my favorite tool to use in AudioTool behind the quasar, slope and reverb. If I am feeling feeling the tone but if I think there is something missing, I'll add the stereo enhancer and a gravity.
I don't remember the names but I have them on favourites - I haven't really been on AT for a while. I suggest just picking out perks which only last a few seconds long and can be polished up with a curve to produce no gritty texture, especially if you are adding a quasar as a reverb. Otherwise, it can get muddled up with the lower frequencies.
