Since the last time I recorded this, I figured out that turning on the velocity filter on my Nord Electro 5D makes the Hohner Pianet sample sound a bit better. While recording this, I actually discovered a few notes I'd missed last time: at the end of the first two phrases, there's a B, and at the very end, there's a G in the bass register.
The parts sound a little bit out of sync for the first twelve seconds or so, but this is better than my last version.
