Clock doubled external hardware

Hi all,

Since I upgraded the clock is doubled for my external synthesizers except the Arturia Beatstep Pro.
The Beatstep is my ‘midi controller’ and I use it to program my Acidlab Miami and modular.
Problem: project is at 130BPM, the Beatstep follows the clock of 130 but my Pro2, Sub37 and Analog Four double the clock to 260.
All the synths are connected via USB, haven’t made external instruments because I don’t want to access them as a VST and it always worked fine. So everything that’s not connected to the Beatstep doubles the clock.
There was no problem in Cubase Pro 10.5 but after I upgraded to 12 it started.
