My EX5 will not load files from the floppy drive. It starts to execute but then freezes the whole synth part way through. If I turn it off and on again, some of the performances will work but the higher numbered performances appear to be corrupted.
I have tried a known good replacement floppy drive and also a usb floppy emulator. They all fail in the same way. The diagnostics report that the floppy drive is OK. So I do not think it is the floppy drive itself.
I thought the other possibility was a memory problem but the diagnositcs report that the memory is OK. I have even replaced the internal battery (although that should not be an issue when the synth is powered up).
Does anyone have any ideas of what might be causing this problem or any ideas for diagnostic tests to try?
