I've been into filmmaking for about 3 or 4 years and I've also been playing piano and have started looking into scoring films using a computer. I've messed around with musical typing in garage band, but it doesn't work well for me because you can't play big chords on it and octaves and all that stuff. I'm looking for a good midi keyboard specifically for use with garageband and similar programs. Also if it had nice instrumental sounds (orchestral/ movie-like) it would help. Any recommendations?
