Hi,
In the early days of synthesizers, when they first were just sounds, and you turned a knob here and there, it was the fact that its sound was not "recognizable" that made it "spacy" or "alien". And, of course, a lot of work in that area, immediately went to connecting this with space and universe sounds, for the effect, and create an image that is not likely to be there, if we were able to check it.
But the image, and the foreign thought of it, was effective in scaring a lot of people to not like the early electronic music, and think of it as "cold", and 50 years later, this is still partially true.
Then one day, someone did a funny thing with Bach, and right after that, another turkey used knives and what not on a huge thing on stage and next thing you know ... no one gives a fart about the sounds anymore, since it's all "notes" and what not.
I have never thought of "human" this or that, in terms of the sound of something or other. Whether an effect is used or not, and the early progressive music was just full of these things, did not make the music any less real or obtuse, although most listeners can not accept it, because it is not radio sounding, or for this group ... DAW sounding.
If ever you want to check something that DAW folks have never been able to do, check CAN, and Holger Czukay in his first 3 solo albums ... the album "Tago Mago" is a bunch of cut and paste, and you do not think of human or alien, despite the incredible array of weirdness and sounds coming and going, and sometimes not making sense, but somehow, it all comes together and sounds fine, and for my ears, and this is the case with "improvisations", this was one of the things that made a lot of music interesting and far out. Compare this to the really long essays that Klaus Schulze has done for 50 years, and I do not find his stuff any less "human", than I do "alien" ... it's simply a "human at work" ... with his equipment and it happens to create something that we call ... MUSIC.
I always think of pop music when it's all too recognizable ... which is kinda dumb for me to think so, but it always feels weird and "cold", as opposed to the other pieces that come off more cogent and human, than otherwise. This is one of the issues I have with a lot of music done on DAW's, when it's very clear that its warmth content, is not replacing the machine sounds at all.
(Hopefully I am not too far off on this, and I wrote this fine)
