How to set up Rc-505 in Logic Pro x

Dear Community,

I have a Loopstation: RC-505 and I connected it over the USB cable. On top I have a Keyboard wich can be connected via MIDI to the Mac or aux to the RC-505.

I would like to record in Logic Pro the sounds I do in the RC-505, If I only use the sounds of the original keyboard, then everything works, I'm able to loop on the RC-505 and I'm able to recored that in Logic Pro as well. But I would like to use the software Instruments in Logic Pro and loop them in the RC-505 and send them back to the computer.

How should it be configured and set up so I can rather play the Software instruments live and to loop them in the RC-505 and record them again in Logic Pro. To have a proper good recording at the end, this is my goal. Would be much appreciated if someone could help me to figure this out. The instruction says that it should be possible to play live with the RC-505 and record that also in Logic Pro as well.
