Midi sync double the tempo (Ielectribe for instance)

Hello there,

I tried to sync Cubasis with iElectribe, so while I press play from Cubasis (not with a MMC start from a midi controller, but that’s an other story…) iElectribe starts, but the tempo is doubled !
I also notice that trying to sync it with the looper of the Voicelive Touch 2 from TC-helicon.
What am I doing wrong ?

Thanks for your help.

Sorry, my bad, I was doubling the midi ports into an external synth, so it was doubling the tempo…
