Hi Rick,
Yes, as often mentioned, unfortunately you can only activate or deactivate the Registration Sequence function globally, but you CANNOT memorize its settings and its On/Off status to Registrations.
If you want to use the Registration Sequence function, I recommend using only ONE pedal for this: Assign "Regist+" on the Genos to e.g. Pedal 2 and set "Regist-" to OFF. So you can still use pedals 1 and 3 as normal.
By the way, you can also use the [DEC]/[INC] buttons on the Home display or the ASSIGNABLE buttons to step through a Registration Sequence.
Best regards,
Chris
