Keystep Pro - Connection to MPC

Hello everybody,
I am new with my MPC ONE and trying to connect my Keystep Pro.
It’s connected with the USB cable, the normal note input works.
But I would like to be able to transfer patterns from the KSP to the MPC.
Of course, this is only possible if both start at the same time, the KSP should be the slave.
Unfortunately this does not work, the KSP does not start.

Maybe someone can take a picture of the settings in the MPC and on the KSP?

Thanks in advance!

SOLVED... send MIDI Clock should be activ!
