[INFO DUMP] I am not sure if I would go with the term "a lot" when it comes to the midi-playback discrepancy. It can be wonderous to hear our music realized in the notation engine; and at the same time, two things can be true at once. Hearing it in the computer is not the same as hearing it live. Just because the computer can do it, does not mean it will have the same effect with an orchestra or if it will be played correctly by an ensemble as the computer has shown. (People have done comparison videos showing Musescore Audio engine vs. a real orchestra. You can hear the results and form your opinions.) It's why we inform ourselves on the properties of instruments and why we study instrument pairings so we have the best tools at our disposal for effective writing. _______________ Ironically, to ask "How do I write better?" is a subjective question and the only answer will be what is great/ good to you. In the literal sense, if you feel you are inefficient or that your music is not accomplishing the standards you want, then there in itself is some knowledge dissonance and it may be your writing process that hinders you. There are a few ways to do this, and asking these questions is more than okay (especially here!). Igor Stravinsky was quoted saying the following: "Good composers borrow, Great ones steal" It is a variation of a phrase both Picasso and T.S. Eliot used when describing their work. One way to learn is to look at the greats, or your composer ancestors. Look at their music and copy it by hand, or by mouse. See where they put the notes and see what instruments... then look at the results. Since you have some music theory training, analyze the harmony and see how they voiced a chord, etc! Try re-orchestrating something if you want; or come up with your own exercises. In the collegiate sphere, at an early point, we were given Bach harmonic progressions and had to write a melody on top in my undergrad. That was a few years ago. Speaking of, do understand that you won't become Wagner overnight. This will take time and that is okay. _______________ If you haven't already learned, most big composers did not compose for a large ensemble first. They composed for a reduced score, as in a simple grand staff for a piano, and wrote out the entire piece first BEFORE orchestrating it. Did you know Gustav Holst wrote The Planets for Two Pianos in 1914, FOUR years before the premiere? He wrote it for keyboard first and then orchestrated the famous work we know today. Starting small and being able to see all the pieces over 2-3 staves is a lot easier than trying to control 17+ staves at your first go. Thus, if you haven't, give this a try!
