If for each Preset, you could annotate it with a short piece of text that is displayed on the main screen. For example, a preset that works best with the treble pickup and an eBow, you could write "Use with treble pickup / eBow" and when the preset is recalled, the text comes onto the main screen. Or if on a certain preset all four of your continuous controller are put into use, you could annotate accordingly so you know. etc. Just a thought.
