[Thomas] just wanted a simple, free drum machine to play with. He decided to build one himself using MS Excel. To get it up and running you need to download a .zip file that contains the .xls and .dll files. Grab some drum samples and you are ready to go. Each drum is mapped to a key and can be used with a game pad. Don’t worry he’s got some simple, Meg White, patterns to get you started. Not impressed? Well, tear it down and build your own machine.
