[SunBlack]

Well here the lcd with my user performance saved:

using command "write performance"

As you can see i saved two guitar sounds, i also changed other parameter as mfx , etc.

I stored too it into usb pen drive using "save sound/system"

When i switch off the Prelude and reswitch it on i found all the user Perfomances (including the above one) but ALL with default sounds/mfx.....

How to recall my Performance settings i stored??
