Yamaha DX7 download sysex .syx files
Found them. Unit fixed
Hi, I had a unit in with a shorted backup battery. Killed the memory. Cust does not have the cartridge. All I get are blurb faint noises, no patch names, at least they are not distinguishable. The basic functional display works though. I'm thinking I only need the sound files.
Trying to restore to factory sounds.
