Problem sync Ableton Hive 2 (arp)


Hi all,
I need suggestions about this problem. I sync Ableton tempo to Cantabile. In Cantabile (sync to host) I use sync for the arp of Hive 2.
The tempo of metronome is perfect in any way.
When I launch the tempo in ableton the arp function dubble the notes.
When I stop it, the arp functions at the correct tempo.
Any suggestions?
