Maximum number of stereo monitor mixes on the CQ-20B?

I would be splitting the inputs so can use the Main LR as another stereo monitor mix, which would allow for at least 4. I’m just wondering if you can use the alt out as an additional stereo mix and also the headphones for a total of 6 independent stereo mixes.

Also how many devices can be connected to the wifi at once (for adjusting personal monitor mixes)?

Headphones can only ouput one of the existing mixes, so can be an extra out if you’re happy to share fader settings with someone else.

Any chance the alt out will get its own mix at some point?
