Digitakt Live sampling, Recording in Overbridge mode Ableton Live 10


I got a Digitakt couple months ago and got it figured out how to set it up on overbridge mode for multitracking and all.

I’ve got a Focusrite Scarlett 6i6 as my interface. I have Ableton Live 10 Suite running DT in OB mode which is midi connected to eurorack and other synths.

Now I still got a couple things which I’m a bit confused about.

I read before that in OB mode it’s not possible to use the metronome and was wondering if this is still so.
Also when I live record my synths in the DT via EXT L+R which comes from my second output on my Focusrite, I can’t preview what I recorded is this also not yet possible or am I doing something wrong?
