Memory card bug with Nordlead 2

[synthpark]

Hi,

I just registered here because of a problem with my beloved NL2:

After owning it for decades, I discovered that with two cards the following weird issue appears:

when I store performance F4, program 1 on the card is corrupt, and vice versa.

In result, the first 12 single programs or so are broken, or programs in the F range or even G range are also broken, depending which was saved last.

I can of course live with that and store only performances (100), but is my unit broken? I have an earlier firmware.
It's very sad, because it was my first synth.

Once I installed the latest firmware but found that midi wasn't as tight as before.
And chorus sounded different. So I went back. The unit doesn't crash or so.

Ok, I delimited the problem: programs 1.1-1.11 collide with performances F.4-F.7.
The rest is most probably fine, checked everything. Not a huge deal.
