I noticed quite a long time ago that once you’ve assigned an effect toggle parameter to a stomp switch on the external footswitch, you can’t then toggle it from the web UI - it shows an error “Can’t change a parameter addressed to hardware”. I have a vague memory of asking about this years ago, and being told that it would be extremely hard to allow this for some reason. Is that still the case, and if so why? I note that it works fine with the two stomps on the Duo itself.
Aware that with the Kickstarter ongoing this is probably a really bad time to be asking non-Dwarf questions!
