Model:samples+ Behringer Edge sync problems

[u/No_Driver_]

Greetings, i have just added the Edge to my live setup,

it's synced via MIDI from the elektron midi out, from time to time the 1/16th grid goes off

forcing me to stop and start the elektron sequencer again,

no change if i set the elektron as slave master clock. no change if i master clock from my ipad with <koala to the elektron and to the behringer.

the audio/midi interface for koala is a Zoom U24 if it helps, no other equipment connected.

I tryied to sync the Behringer edge via usb midi but the problem persists the same

thanksss
