You are right. I forgot, how old I am.
Oldschool for me, is what happened before the 90ies (in terms of music style). 303 acid chirps thus is more the modern area of electronic music.
But the factory presets of Pigments are more covering these Vangelis, Tangerine Dream, whatever esoteric stuff, what for me is some kind of meditation(or should I say go-to-sleep?) music.
