There\'s been some recent discussions about \"what makes orchestral mockups sound good\" and I still really believe it has mostly to do with composition and orchestration and balancing than anything else. To give an example I\'ll post a mockup of part of the Star Wars \"Across the Stars\" love theme I did some time ago. No expression whatsoever was allowed: no volume changes, no x-fading sample programs. Everything you hear is velocity switched.
Of course this could be improved quite a bit with expression and using x-fading programs, EQ\'ing and paying more attention to reverb - also I think I left out most of the woodwinds because I couldn\'t figure out what they were doing in the tutti
Anyway, I think it still has an impact on the listener and still sounds, if not good, then at least decent in this very rough state.
