Archetype Gojira Expression Pedal

I recently bought Archetype Gojira and my first interface, I’m very new to all this stuff so I’m not sure which pedal I should get let alone how to connect it. I have the Komplete Audio 2 for my interface and if I need midi I can buy a midi to usb adapter. I’d preferably spend as little money as possible and only need the expression pedal part

You’ll likely need something with an actual Expression Pedal input or get a MIDI floor/foot controller with an expression pedal built in… I have an Akai MPK249 and Behringer X-Touch which both have expression pedal jacks and both work great for controlling the Corey Wong wah
