We have 2 out of 5 buttons programmed to do something, leaving the other 3 unprogrammed. If somebody comes along and pushes one of the unprogrammed buttons, the LED latches on. Should I record presets that do nothing for those unused button or is there a better way to keep the LEDs from latching? If the recommended way is recording null presets, what does one of them look like? Is it even possible to record a preset that contains no dimmer level information?
