I just go the looper and I’m still struggling to understand it’s functions, It is a lot to grasp

I went trough manual but I didn’t figure out some things and I would appreciate some help.

1.
Can I use this looper to quantize without having to set a tap tempo? Can I set it to detect tempo automatically, and show the tempo it detected with blinking, like a simple BOSS RC-3 or RC-30 loopers do?

2.
What is quantize to the beat? It is mentioned in the manual but I can’t find anything abou it.

3.
I’m asking the first question because taping tempo option is annoying. Even if you have to tap the tempo, other loopers I used started counting the tempo from the beginning of the bar when I pressed the record loop button, here this does not seem to be the case.

Is there an option to turn on so that the looper to starts counting the tempo from the beginning of the bar when I press the button for looping?

I don’t want the rhythm machine to be heard in the background so it seems impossible for me to guess when the looper is in the first beat of the track with just looking at the tempo light. When the loop is played back I either end up with a silence before the starting of the loop or playing back just a part of my recording. I don’t understand what is going on, I see the red rec bar blinks like two beats before it starts to record, but this is really annoying, I want the counting to start when I start recording the loop.

Thank you.
