I think there’s nothing worse than a drum loop being full on smashed the way people are and do with things like the heat and the Sherman etc and especially now we have the Internet for people to show it happening in all its transient reducing glory, oh lol, full frequency distortion in one uncontrolled effort is awful IMO.
In ambient I’d use the heat on a very small send return basis and I’m betting with care and a Little engineering/experimentation it would sound great across a track if used sparsely, tbh i would buy a nice fx box over heat if all I was doing was ambient.
Throbbing ambient as Andreasroman mentions sounds interesting
