This app allows you to connect your phone to an Arduino ESP32 to control an ETC Express lighting console through a MIDI connection. This Arduino device must be present to work.
You can load cues between 1 and 998, advance to next cue on either the A/B or C/D fader pair, run any macro between 1 and 998 and trigger the bump buttons on the submasters.
