Korg Poly800/EX800 Users

I do not think so (you speak about Parm 86, right ?)
Anyway, I just made a test with 86 set to 1 : same result. I can write whatever I want in the program parameters, it is never replaced by the sysex data.

To make sure that the Write Enable switch was not broken, I tried to store a parameter with the switch set to Disable : EX800 does not accept when I try to push the Write button (so I assume the Write Enable switch is working)

The data I see in the changed parameters are still the same than BEFORE uploading the SYX file. It looks like the synth is ignoring simply the valid SYSEX data. If I reload the data from cassette interface, it works (the parameters I have changed are restored to original value)
