I've uploaded a file describing the sysex format for firmware 
updates to the web page.

The update can be done just as a raw sysex file, as long as there is 
enough delay between blocks. I've been using Midi-OX successfully 
for this. 
I will be writing a dedicated utility for Windows when I can find 
the time.
Anyone fancy writing a firmware update utility for Mac/Linux users ?

Cheers,
