Thank you for the replies.
I’m buying this for my studio to replace a Presonus StudioLive, which has a solo button, and I’m used to using it. The fact that a solo button is a bad idea in a live setting is a non-issue for my needs.
So my suggestion per the OP would be to give us a menu feature that let us switch how the PAFL works. As in maybe have a checkbox that let us use the PAFL as a SIP. I find it useful for debugging multi-mic setups.
As an example, a common issue when recording drums is there will be a rattle somewhere, or maybe hi-hat bleed somewhere, or maybe a squeak somewhere (yup people need to maintain their kick pedals on occasion lol). Being able to solo things off and figure out where that problem is is has proven useful.
It’s not a make or break for me, but it’s just something I would find useful.
