(installation instructions are on second tab of that webpage)
For those of you who don't know what it is all about, Megadrum Config Tool is an application programmed in Java that makes easier the process of configuring all the parameters of Megadrum. Connect Megadrum with the USB cable to your computer and you will be able to configure its parameters. Depending on the operating system you have, you also will (or not) be able to update the firmware directly within this application.
