Articulations and Dynamics do NOT sound the same exported in other programs (from Musescore MIDI file)
As a classically-trained composer writing orchestral music exclusively, I noticed that what sounds great in Musescore, doesn't sound the same in professional "Hollywood grade" sound libraries, or other notation programs like Notion 6. In fact, after careful study of music theory and examining the scores of Wagner, Stravinsky, and Beethoven--I rely on a combination of playback sound and informed "hypothesis" based on what I've observed (i.e. correlating notation symbols with sound during live performances/recordings)--I know that what sounds good with a real orchestra doesn't always sound good in a scoring software, so I rely on theoretical knowledge rather than midi playback for what is "realistically-correct"!
Know that I do use volume dynamics (p, mf, ff, sfz) and slurs (for violin bowing), along with pizzicato, staccato, and all standard articulations one finds in late-romantic German and Russian music.
That said, I write all parts based on how it sounds in Musescore, and often it's a shock to hear it in programs that claim "real samples from London Symphony Orchestra"--because the tempo is slower therein, the tremolo sounds thick and sloppy instead of a crisp, dry fluttering, and recently someone rendered my symphony in a mix of Hollywood sound library and Logic and the woodwinds are disproportionately louder than brass and strings (a single Clarinet isn't supposed to dominate Horns and Trombones!!!). I wrote my 1 clarinet in piano or mezzo-piano (mp) with 2 horns and 2 trombones in MP or MF (a trumpet comes in somewhere too).
My question/concern is: I am unsure if exporting to more "realistic" sound libraries is desirable anymore, since the music only seems to sound "perfect" in Musescore. Additionally, how does one truly know what one is writing will sound as envisioned, considering these pieces never sound quite the same in every software? Which is the "more accurate" version? How can you really know until you attend an orchestra rehearsal?
I am strictly-traditional, and execute musical craft according to 19th century ideals, values, and methods. Music must always be done with real performers/orchestra--and I absolutely-refuse to use digital "mixing" and turning a bunch of knobs on a mixing console because that isn't a composer's job--that is the place of producers making electronic music who speak of "frequencies". We traditional souls spend our lives learning the theoretical dimensions to produce Visions, and our form of "mixing" is called writing Italian phrases above staffs to indicate louder or softer!!!
I use musescore to write/engrave, and I did consider making MP3 files and selling them as "digitized orchestral music" in case no orchestral would perform these compositions. I deleted Notion 6 because 1) to actually "score" music therein is the most convoluted, confusing series of clicks, commands, imputs (totally NOT expedient or user-friendly) and 2) the "real orchestra samples" sound like a worn-out 60's Mellotron!!!
So I decided to go the traditional way, however, I must be sure that what I'm hearing is how it will sound then and there--any way to know this in exact precision? Any way to rest assured all will sound as envisioned?
