I am about to purchase a SL III 16 for a marching band setup. Since it does not have User Assignable Buttons on it, is there a way to easily advance scenes by assigning Scene + and Scene - to some buttons on the Fat Channel Section? Or any other buttons on the mixer for that matter. I'm sure that there will be some buttons on the mixer that I will never use, I would like to be able to assign scene +/- to two of them. I am worried that quick scene changing will be tough if I have to navigate to the Scenes menu.
As much as I would love to get a larger format mixer that has User Assignable buttons, it is not possible due to space restrictions.
