I got the factory presets from the Spanish distributor in a .MID file. It has a sysex message containing the necessary data. Of course, you need a PC and a sequencer program or a sysex utility in order to send it. I am sending that to you now, but I write this here in case someone else wants that too.
I must say that I haven't tested it yet! :-)
