Moinitoring Instrumenttracks hickups

I have noticed lately (don’t know if that started with Cubase 10 or one of the small updates since, but I am fairly sure this wasn’t the case with Cubase 9),
that while monitoring/recording Instrument tracks there are some hickups every 5-15 seconds (a single note doesn’t get played). The note is recorded and plays back fine when the recorded file gets played back. I have tested this with SD2 and UVI Workstation.
It only happens when “All Midi” is selected as input. When I chose a specific Midi port as input this doesn’t happen. I have already tried the system time setting.
What could trigger this and is this already a known behavior ?


If you are on Windows, could you test your system via LatencyMon, pease?
