Nick please sorry for my delay but  I have just finished to try to copy again…..well now I can explane you exactly the situation:

The preset that I try to copy is the 290 (Buenos Notches).

I load the preset in this memory location ,it's working well.

The first thing I do is to try to copy it on the cartridge, (Mem.location 516)

after the copy I load the preset that I have copied,it working well in this case too.

The second thing I do is to try to copy this preset from cartridge to memory location 19 the copy process is OK but when I try to load the preset the Eclipse is crashed.

I re-start the Eclipse.

The 3 thing I try is to overvrite the 19 location with the preset located in memory location 290 ,the overwrite process is OK but when I try to load the preset the Eclipse is Crashed again

What do you think?

AAAAAAAAAAAAAAAA…………………………

I forgoting another important thing :If I don't Copy but I Save the preset on memory location 19 It working well 

Now !  What do you think?
