Help-Poping digital noises out of my MD

Hi
I start a new live project with ableton and my MD sps-1uw+, and had a small and annoying problem.
The MD gets it’s clock by midi from ableton, while working I start hearing some popping digital noises, mainly when the clock run’s, but even when the clock stopped.
it’s sound a little bit like buffer noises.
anyone had this before and can tell how to avoid it?
I’m adding a recording of this sounds. https://drive.google.com/open?id=1IMxd2uf-jJXcJcfyYMDjqQGP7n-zbzmp

Thanks a lot
