no, there are no sampled loops, licks, eads or whatever: everything is edited note per note. a little exception to this are the rolls (timpani and cymbals), which are short looping sounds controlled using expression MIDI Control Change (#11)
Agreed with all comments above except the “you should do soundtracks” one.
This piece could so do with a little stereo depth. I could really get lost in it then, but right now, with these in-ear buds, the lack of stereo detail is really obvious. It’s the final “au naturale” touch I think. Those places some of the others have picked up as “sketchy” or as gaps would fade away nicely I think.
I agree you probably won’t be able to produce soundtracks on demand and still enjoy your work. I wonder where purely creative orchestral scores might make money? I think you might need to look to the old composers to see how they pulled it off (music as political diplomacy perhaps?).
