The Quaverato should work with any device that sends MIDI messages, but it doesn’t work with expression controllers. The VPM-1, our volume/expression mod for the Ernie Ball Jr pedal, is not a MIDI pedal…it’s only capable of sending expression voltages, so it wouldn’t work with the Quaverato without an expression voltage-to-MIDI converter.
In the lab, we used the Behringer FCB1010 to test and design the Quaverto, as well as the Disaster Area DMC-3XL (which also can convert expression voltages to MIDI). So I know those 2 controllers work, but basically anything that can send MIDI messages can control the Quaverato.
