Sunset, Riverside and Iridium can all be controlled by MIDI, but not at the same time. However, our friends at Empress have the solution: The MIDIbox2 is a MIDI splitter that allows you to feed in a MIDI signal, and then split it into four separate outputs on ¼” jacks. This enables you to get MIDI control of Sunset, Riverside and Iridium simultaneously.
