Thank you Klaus; I already contacted Synthax but they offered me a new Eprom chip for 25 euro + shipment, that's why I was hoping to find that "bin" file for burning an Eprom myself with the right tools, considering that I spent just 50 euro for the MP44...

Hello! I'm desperately looking for an EPROM image file which was originally available on the Miditemp site; it was named mp44v207.bin and I first discover it on an old forum post: http://www.miditool-board.de/viewbeitrag.php?themaid=0300000454&areaid=03

I recently bought an used MP-44 (old version) with operating system version 1.09, and having spent only 50 euros for it, I would like to try an upgrade without spending too much money.

Is that EPROM image file still available somewhere? Maybe there's a user of this board who still have it!

Thank you so much in advance for any help you may give me about it!
Best regards
