Background: I have a Roland FP10 digital piano that I'd like to use as a midi controller, ie connected to a laptop running a daw, then out to headphones/speakers. I'm far from being a serious musician and really just want to play around with an expanded range of tones, rather than restricted to the few instruments built in to the Roland.
This might be a silly question but how does a daw generate its sounds? Does each daw come with its own "samples" of the instruments, with the quality of those sounds dependent on the particular daw? Or do all daws use the Windows GS wavetable synth (and if so, is it possible to replace those sounds with a better quality set)? The only time I've done anything with midi was with a freeware Windows app (I forget the name), which used the GS wavetable, so sounded very poor,hence wondering if all daws do the same.
On a related note (pardon the pun), if I wanted additional tones, over and above the "general midi" instruments, what should I look for in a daw? Specifically I'm interested in 80s/90s pop/synth sounds.
