I wanted to share this display interface I created for the PBC. It uses an ipad to display each button page as well as a persistent overview for which loops are active, which pbc switches are active, effects enabled on a Ditto x4, and expression pedal feedback for a source audio reflex expression. The interface reacts to midi messages to change pages automatically as I switch on the pbc and also reflects active/inactive buttons/loops/switches. Im excited to share it, let me know what you think!
