XDJ R1 4 Beat Sampler Use

Hi everyone,

I have a question about the 4beat sampler opearation on the xdj r1. I have searched the user manual but i didnt find any info regarding my question. I would like to know if there is a way to play a sample in loop after it is recorded without having to hold the button. I just want to press the button once and let the loop play so i can have a background loop playing and mix songs along with it. It is a bit inconvenient to have the button pressed all the time in order for the loop to play.

And one more thing, is it possible for the console to display a track's bpm before i load it on the deck? I want the bpm to be displayed when i am browsing through tracks.

Thanks!
