* Open performance in RM3 for editing
* Make a change to slot 1 -> Store Performance in #x button becomes active
* go to another slot for editing -> Store Performance in #x becomes inactive (even though unsaved changes are still in memory)
* Need to make a change to activate the Store button again
Store button should stay active across all slots in a performance once you've made a change in any one slot.
Cheers,
Torsten
