1-Four STS instrument setting at the bottom of the screen.
2-I want to change the instruments (STS) and save them in a Performance.
3-I cannot change the instruments in the STS. Does this have anything to do with the Global protection? (Lock)

On my Pa800 this is a simple procedure:
1-Change the instruments and the settings.
2- Select from the performance.
3-Select from Tab at the top; Save One Touch Settings.
4-Then I select where I want to save it – 1,2,3,or 4 STS. Done!

A little confused but I’m getting there.
