I just received my Nova System the other day and haven't had much time to play with it yet. I've looked at the manual and it did not answer two simple questions: 1. How to switch between Pedal Mode & Preset Mode? My guess is to hold down one of the Preset buttons for a few seconds... what's the deal? 2. There are 20 banks with 3 presets per bank. Are any of the presets already programmed with blocks of effects or are all of the 60 presets 'blank' for user programming only. These seem like basic questions that should have been answered in the manual.
