I wrote this song using Famitracker, for my game, Snailiad! :-) You can download the rest of this soundtrack from my site (auriplane.net), including the NSF files, if you like.
This is the final battle theme, for the second battle with Moon Snail. It's supposed to be high-energy and a bit hectic, alternating between syncopated portions and steady 4/4 pulse sections, and maybe a little big progged up. It's also one of the longest loops in the game, and the only song where I used fast arps (although I had to set the tempo pretty high and program the arps by hand to get the effect I wanted, rather than using FT's arp effect. Famitracker's arps aren't terribly configurable.) Anyway, I hope you like it!
