Question about Music
I have a Yamaha DX7 IID, with Grey Matter e! card installed. The previous owner correctly replaced the 3.2 volt battery that maintains internal memory when there is no power supplied. I believe he replaced the battery in the hope of correcting an internal memory problem. I find that that there is no access to the keyboard internal voice and performance patches and that I cannot reload them from the supplied ROM cartridge that came with the keyboard. Can you please help?
Go to http://www.thedx7.co.uk/ Click on 14 Battery Change which is a walkthrough. You will; have to do a sysex data dump to restore the sounds. All that info should be on that site as well as some other great stuff. Hope this helps.
