Last question; am I right in thinking that the only way to map an aux switch to a hot switch is globally, in the system menu? IE, I would need to have them like that across all patches?
Not necessarily. The only functions that can be mapped globally are the ones found on this list: https://cdn.eventideaudio.com/manuals/h90/1.8.6/content/appendix/global.html; they correspond to Global-Pedal Control and MIDI-Global Control functions. Some other Perform Mode options can only be mapped on a Program basis, like the looper functions you asked about previously.
