Quick helpful tip using the lock control. When you press the lock button, anything lit up will be 'locked' - any locked items will stay the same from profile to profile. For example, when I'm playing live I'll adjust my delay setting to suit the venue, and with it locked then every time I change profiles, it keeps that setting.
Here's another use though - say you want to write the same effects settings to several profiles at once. Just use the lock control to select the ones you want to be applied, then open up each profile and press store once, then replace. This saves the locked settings to that profile. Great for changing several profiles quickly and easily. I used to use copy and paste for this, locking is a lot quicker and something that I don't think many if any guitar processors had before the Kemper.
