Here's a test track. All done in garageband. Looped drums. Bass is my guitar pitch shifted down one octave.

I'm surprised at how many people are still using older versions of ACID. Acid pro 5 is only $200.00 and Acid Music Studio 6 is only $69.00. For $69 you get ASIO support, VST and DX support which is totally omitted in older versions of AMS. Time to upgrade.
