Synching opz with audio kit synth one through AUM


I cannot get the opz synched to synth one‘s sequencer, whatever I do.

When I try ableton link to AUM the opz‘s tempo freaks out, like a quarter of a beat very fast then very slow repeatedly.

is there a way to synch them? would be great to let the opz robot away and use the synth one to arp along. Setting them to the same BPM drifts apart very quickly.
