I'm just checking out A.I.R, a pretty decent and useful library, based on Kontakt Player 2.
But it's not even possible to edit attack and release envelopes!! There are a few preset modulation routings, but absolutely none of the basic editing functions to shape the sound.
I thought the Kompakt Instruments, with their fiddly browser and almost nonexistent modulation routings, were poorly specified, but this is even worse!
I mean, is this progress? Every hardware synth I've ever owned allowed you to edit envelopes to shape the sound. We are being forced to remain preset-bashers, because the current libraries in Kompakt (and to some extent Kontakt) are impossible, or so unfriendly, to edit.
Give me exs24 with its easy tweakability any day of the week. It hasn't had an update for years, but you can do a lot with it, and you don't have to squint to load a patch, either.
