I'm a high school age, but very serious musician who enjoys composing for small ensembles, jazz bands, orchestras, and even solos and electronic music (I currently use Fruity Loops for that.) However, with the option to obtain such fine pieces of music software as the Logic Box Set, I am most likely to going to purchase a Macintosh for that. My question is: With Recording, mixing, editing, and making electronic sounds and songs, how much external equipment do I need? And then, if I want to take this to, say, our school auditorium, and use their sound system, using my Mac and Mainstage as my main centre, what sort of things would I need to have? What kind of technical knowledge/prowess may I need to do these kinds of seemingly complicated tasks? I am not rich, so I have a fairly small budget beyond the laptop and the software itself...the most I have in terms of sound are amps, instruments, and cables, and whatever sound equipment the school may have (not much). Would only having these things seriously inhibit the usefulness of getting Logic and its included software? And any information anyone can give me regarding making, editing, and mixing using logic studio and its other included programs would be helpful. Thanks all.
