MIDI Box to CTL/EXP input

Hello, I’m interested in purchasing a Boss pedal that has an expression input labeled CTL/EXP. I was wondering if the Morningstar MIDI Box would be able to control this pedal provided the proper cable connections were made?

What Boss pedal is that? I don’t think you connect a MIDI output to this CTL/EXP input, and definitely not with the Omniports as well. If you want to control the CTL input, you’ll need to use the relay box to interface with the Omniport: https://www.morningstarfx.com/relay-interface

Maybe we’ll have a better idea if we know what Boss pedal it is…

Hey James, I was looking at the Boss SY-1.
