http://www.supload.com/sound_confirm.php?get=341958390.wmaMy rendition of Rainbow Mario complete with speed-up and power-down sound effect at the end. Also threw in a little "trill," I guess it'd be called in the beginning for a little "zest." Please take a moment to listen to it! It's just about perfect! Finally got the harp part, FINALLY. (Oh, my microphone used to record this requires you to scream into it to pick up sound, so you're most likely gonna have to crank the crap out of your speakers.)
It does sound like it's slow in the first two measures-- it is because when I was recording the first bit, I almost forgot which notes to hit, so I had slowed down by a fraction of second, it seems, but I held onto it, so I thought, "Okay, I'm doing good... I don't want to record this single part for the 50th time."
After that, it straightens out and is fine. Yamaha DGX-200 was used for this. Used a steel drum, also.
Sorry, you'll have to download it to listen to it...unless someone can refer me to a hosting site that the URL takes you directly to the song.
