I'm having difficulty with the user memory. I'm not sure how to save the new setting for the buttons on channel 1. I'm using this as a MIDI controller with MainStage and have changed the buttons, B3-B8 to ctrl 103-107 controller numbers from the default, but can't figure out how to save the setting so I don't have to reprogram every time it's connected to the computer. I am a really green user of MIDI equipment, so, I'm sure it's operator error on my part.
