But how to get beatmatch??? Resync button is inactive

I've tried before sync with MIDI clock. Resync worked but BPM is lost randomly...
I'm using a forced solution right now:
I set a VirtualDJ script in VDJartnet plugin. It send automatically TAP & RESYNC signals to Resolume. Also I made a DMX shortcut to TAP and RESYNC button in Resolume.
This is not a perfect solution but it works

It would probably be much better to use the Ableton link (if resync button worked)
Any idea?
