yes! having a reference book like that is really great!and, there's some free stuff on line here:www.dolmetsch.com/musictheory42.htm it's been so long since i took orchestration, i don't even remember all the clefs. was trying to relearn them a month or so ago - but forgot what i wrote about 'secrets to learning clefs.' it's on one of these threads around here. you know when you hear a great orchestration. rimsky-korsakov seemed to be one of the greats - so you might google him and see if there are any excerpts of his book on-line. this stuff must be SO much fun when you get really fast at it. just like orchestration for movies. john williams must be the one to look up for that! and, a few others. also, i vaguely remember seeing a program that played the london symphony orchestra instead of midi sounds. it's probably $1000. or something - but, i'd go to a school where they have something available to you for free. don't know what west chester university is coming up with for theory classes - but they have a BRAND NEW music building - with all steinways (i know i keep saying this) - so maybe they'll have some up-dated technology, too. i know they offer laptops to students and have quite a synthesizer lab. have to look up when this is all available. if you are a motivated student - you should just go for it. it takes an awfully long time to write it all out by hand - i would think. say, i know what you could do - take a portion of your concerto and go to a store that has some of the technology you are interested in and ask to try it out. then, get a print out of your work so far. then, you can use that to show for your college entrance. who knows. if you have good grades - you could start applying for grants and scholarships.
I think pianistismo is talking about the Vienna Symphony orchestra stuff. I think that's the name. It's at least $1,000. Probably more like 5K. Yeah. Ouch.https://www.ilio.com/vienna/ Yeah, 5K...Once you have it all, you have to learn how to use it so it ends up sounding like a real instrument.Beyond the MIDI stuff, you could find a real orchestra to play it. A college one. It sounds like you're in school. Have your school orchestra play it. Then rewrite, rewrite, rewrite.
