I really want to invest in Symphobia or Embertone plugins at some point but can't afford it right now, I have Ableton suite though which includes basic orchestral samples (the solo instruments sound very fake though.) For piano I have the Addictive Keys Grand (came free with my soundcard) which is okay, and the Ableton grand which is about the same quality.
I've made a little demo here, any tips on how I can make the instruments sound juicier and more natural (besides playing with the velocities)? I'm struggling to get used to mixing/producing this sort of soundworld!
