i am sure that frank zappa on his synclavier in the late 80s could have done a cool OST for pretty much any game.
it would've been interesting, at any rate.
he did the bedroom producer thing atleast 10 years before any of us. only that it cost $100.000++++ back then.
the synclavier had its own qualities and intricacies that are incomparable with later tech, i guess (i heard it`s more like resynthesis), but basically, it`s soundfont v0.1.
we have way too many options. we really only need time and experimentation. i mean, if you wanna do it with heart.
if you wanna do it with speed, you need the libraries.
easy, right?
