No, what I actually did was take some midi files, put them in GarageBand, and just by changing the instruments, I “remixed” them to sound somewhat different. If I were one of those annoying people, I’d probably say “simples”. But I’m not.
Here are two tracks I’ve done so far. And by “so far” I know I’m suggesting there may be more in the future, but don’t worry yet – that might never happen.
