Sync to midi fluctuating wildly (Osirius)

This evening i tried to use Osirus as an arpeggioed bass sound with the rPI (Vangelis). So i setup my DAW (CwBBL) as usual when it comes to external hardware or VSTs, expecting Osirus to play along in my chosen BMP (70 in this case) but it fluctuated wildly between 156-164BMP regardless of what i did.

I set the UI to the clocl source to external midi and of course in the DAW i set it to sync my rtpMidi (Zynthian) to midi sync.

Regardless of what i did, the Osirus arp played along using its own weird tempo-setting and i wonder what is the secret sauce to make it sync up with the DAW? I totally respect that i might have overseen something here that perhaps is tricky with LV2, but i can’t figure out what…

It seems like zynthian receiving duplicated clock messages.
Are you sure your DAW is the only clock source?

Regards,
