Are the muted Cabs take up memory ?
(i know that blocks do, even If they are muted, in order to prevent memory overload).
There is no way to not instantiate a cab in the can slots, so i was wondering what's the suggested workflow on that. Install a very "small" memory consuming cab where you don't need one at all and mute it...?
Bro... you post like 104 questions per day seeking the ideal answer to your tonal quest, and none of us know what outcome you seek to achieve by your question. Nor have you posted any clips of your existing tones, tones you specifically seek (unless I missed it totally possible), or recordings of you using the Axe-FX III.
No offense meant seriously: just throwing it out there that you're like a kid in a candy shop asking for all the ingredients and nutrition facts for each piece of candy in there. Not a bag, a bar, or any bulk candy, I'm saying every single piece... of candy...
If I had to be predictive, you are testing out cab IRs? Yes, a CAB block in a signal chain not being active consumes CPU to some degree. With the power of the Axe-FX III, this should not be a concern.
In the odd case I'm correct that you're testing out cab IRs, have channel A be a cab, B be a cab, C be a cab, and D be a cab in your CAB block and
keep it active switching channels in the cab block.
As Obi-Wan told you at Mos Eisley, "what the frick kind of fricken droids are you looking for bro?"
