I am using garage band, but not those samples on this piece... I used the "Deep House Dance Beat" and "Acoustic Picking 18" loops, as well as the "Shimmering Flute," "Nakamal Bass," and "Lunar Strings" patches, and sundry samples of individual percussion instruments.
Come to think of it, I used the "Effected Beat" and "Orchestra Strings" loops on the other song I submitted on the same day as this one, so you're probably reviewing the wrong song here!

I need to start hooking my laptop up to a subwoofer -- the stuff that comes out on the internal speakers sounds *completely different* than the same file played on my old desktop, and both of them sound quite a bit different from the internal playback in garage band. Aaaargh!
