You obviously have not looked very hard in the Genos Owner's Manual for this information!
In chapter 7: 'Storing and Calling up Custom Panel Setups - Registration Memory, Playlist' there is a section starting on page 93 (of the English version) titled 'Registering Your Panel Setups'. The first topic in this section is 'Saving and Recalling Custom Panel Setups with Registration Memory'
There is a note at the bottom of this section which says...
Note:
The panel setups registered in the numbered
buttons are maintained even when
you turn off the power. If you want to
delete all ten current panel setups, turn
the power on while holding the F# 6 key
(second right-most key) on the keyboard.Of course once you have an empty bank, you can save it while still empty so that in future you can call this up to use for new banks at any time without needing to turn the power off and on. Just remember to save any banks that you make starting from it with a different name!
It's 'incredible' what you can find in these manuals isn't it!
