Bank Changer is a Windows application that allows you to switch banks in the Multi-mode of the Korg This program is not just limited to the Korg 05r/w. I am sure that it works on the rest of the 0-series and on the X-series. However, this has yet to be confirmed All you have to do to work the program is check the Channels that you want set to the A bank. The other channels that are not checked will be set to the GM(general midi) bank. There are shortcuts if you choose Select All or Unselect all. All in all, it should be pretty self explanatory
