Web-based Downrush - no FlashAir needed! Or installation!
The latest fashion in Downrush is web-based hosting. The first product to be web-based is Midian. All you have to do to use Midian stand-alone is to go to this web page: http://www.fentonia.com/catnip/midian/.
You use the "Choose File" buttons to upload your .mid file (and if desired, a SONG.XML file). After you grab the tracks you want, you press the "Download" button and the SONG.XML file is downloaded like any other download you do on the web.
So zero installation is involved. You don't need a FlashAir card or even a SD Card to make this work.
(It does help if you set your web browser program to let you change your download directory and file name. Instructions on how to do this are out there).
