Thanks Harry

I'm mainly concerned with Rhythm and Sound settings not holding when turning on and off.
I Don't think Rev 1.4 or 1.6 affect this.
I've found out this is affected by how long the keyboard is on a few minutes may not work.
Also the menu settings and age of unit can affect it.

I don't see this as a problem. Settings can be saved to a SD card. This is most permanent.

Thanks again.
