I guess this warrants a little back-tracking then - I looked up my service emails - though this is a side-topic.Yeah you were definitely doing something wrong. The ES5 always had that ability. It has assignable control buttons as well.
What I was trying to do was add an EXP pedal to an ES-5 setup that already had an external switch. That’s not an option with the ES-5 - you can do one or two switches OR one expression pedal - which is why the expression pedal would only toggle on/off. At the time, I needed both, so I added the DMC.micro to give me that. That also gave me two more switches on my board - I figured I’d utilize them - it was inelegant.
So, I did a size comparison of the ES-5 + DMC.micro + foot switch with an ES-8, and realized that an ES-8 would give me more onboard assignable switches and the capability for two expression pedals in a better layout and not much more space.
7 onboard switches on the ES-5. 12 on the ES-8, which made an external foot switch unnecessary.
I still use the DMC on a small board - which consists of an ADAM, an H9, an expression pedal, and sometimes the FI - all patchable and midi-capable.
