Does anyone know any good composition programs

[colin012]

I want a composer but I don't wann bay 200 bucks for crap... Give me what you think is the best program for $300 and judge it by these factors:

Good sound quality

Varity in instements (Looking for rock and orcistra and a therimin)

Able to save mp3s midis and wavs

Saves don't take up to much file space and will play quick and smooth if used on a web page


Thanks.
