Sorry to ask that if it is already answered elsewhere, but can these levels be saved as part of the settings for one particular pedalboard ?
You can use “user profiles” that save and load up to 4 collection of settings.
We don’t recommend to save/load hardware levels on a per-pedalboard basis, as that can damage equipment.
Specially dangerous in the Duo X (with the upcoming v1.9 update) since the CV / Headphone / Exp.Pedal modes are part of those “alsamixer” levels.
It is technically possible, but it is not going to come from our side
Damage equipment… you mean blow the amp ? Another practical example of it ?
yeah, something like that. very unpleasant if you expect 50% volume but suddenly it changes to 100%.
on the Duo X, the output headphone optionally acts as CV out. so an alsamixer switch could make the headphone receive 5v
