Hello Nigel,
Putting in the original supplied floppy initial data disk the K7 screen shows up as Midi ----shows 4 segments on the disc --- If I endeavor to change to the Tech screen shows nothing on the disc .
Original problem showing it fangs

Midi and Tech reversed to where they should be.
I did load all the 4 items separately when it said Midi Mode and it did nothing to correst the problem
In a few days time my computer friend will assist me in doing the more extensive tests as suggested by Technicsplayer

Maybe there is something I don't understand as to how to overwrite the flash areas of custom memory,home page favourites and user midi settings-----presumably those memories can't clear because of the Tech to Midi crossover.

If there is anything also I could try lets know .
