With this modular controler, you can plug up to 12 footswitches (sustain pedal type) and 6 expression pedals.

What makes it unique, is that each footswitch can send up to 4 different MIDI messages. That means that you can for instance control 4 individual track Mute buttons, and have another pedal that will mute them all. Or you could clear 4 individual Loopers and have a “Clear all” button…

Its software editor let’s you specify the messages you want to send.
It’s got Midi Out (DIN) as well as USB, and is powered by a wall outlet, so you don’t need a computer to run it.
