Is the selected I/O Settings Preset saved with the actual Preset so that we can change guitar (or Bass), change Preset and have the right input level?
I’m not sure about this, but at least when more than 2 outputs are assigned in the rows in a preset, the output gains of those outputs appear in the headphone output setting and saved in each presets.
as far as I can tell they are Global, you can’t assign them to individual Presets. I’ll ask Support, but I don’t see any indications of how they’d save per Preset level.
