It would be nice to implement a "Lock Override" option, allowing the user to select - in a a particular Rig - if an effect slot would "override" the generic "locked" effect assigned in that slot.
This would open a myriad of possibilities, so that we could chose a "generic" effects set (Locked Slots) which could find an exception in a "per rig" basis.
One could use a "generic" reverb for all rigs except for those others that a certain particularity claims for a "overriden" reverb.
The "Lock Override" could be assigned using one of the soft buttons above the screen (maybe the fourth one).
What do you think?
