The remote user doesn’t need an account - search for ID login - I prefer this method
Nobody can forecast how good your connection is, you need to do a test as there are a lot of variables
It’s worth a quick initial test with a spare laptop, using a tethered mobile phone (SE doesn’t work over a LAN). Just so you have experience of what the performer will see.
READ UP on the control room, especially if you are not used to working with older analog consoles - the routing can be confusing if you are used to just recording solo.
I used it with remote performers who don’t even know how to switch a computer on so that part should be fine
Try the FREE and included version of VST connect …the SE one that is bundled with cubase/nuendo. No need to spend any money just yet.
Personally I’d highly recommend you invest - because it helps future development and there isn’t, currently, anything quite as good for remote recording…
