Thanks! So you use this to control buttons, like presents or up/down, etc. and then use the Stomp's expression out port for the expression pedal?

When you say midi switch, do you mean like a midi footswitch, something along the lines of: https://www.amazon.com/HOTONE-Controller-Bluetooth-Ampero-Control

Thanks for answering. So if I use the Mission SP1-L6H Expression Pedal plugged into the expression port on the Stomp, then I can also have one footswitch, but not two footswitches, right?

I have a Stomp XL, a Rock Stock 2-button footswitch pedal, and just purchased a Mission SP1-L6H Expression Pedal. I originally thought I could use a Y-cable from ext. port on the back of the Stomp XL and have one end go to the 2-button footswitch and the other end to the expression pedal. However, now it seems to me that if I want to use the expression pedal, then I can only have one button on the footswitch available, not both. If this is the case, then could I have the Mission SP1-L6H Expression Pedal put before the Stomp in a signal chain? Like guitar into the expression pedal, and then expression pedal into the Stomp? I have a different wah pedal (Hotone Soul Press II) and I think I can set it up that way. I had bought the Mission SP1-L6H Expression Pedal simply because I thought that I could use that along with a two-button footswitch, but I think I may have been wrong on that.
