Flippin' sweet!
I really like this song. The oboe and brass themes with the rolling timpani give it the "military anthem" feel, while the plucked strings and high-pitched xylophone-ish percussion reflect its more humorous style.
So, are you using EDIROL? I have it, but I haven't submitted anything with it, I can't do good enough with it yet. I can do percussion adequately, but I can't get a good melody without the use of a keyboard.
