MIDI out BPM are dynamic and messing pedalboard delay

Hi again to all,
I’ve made additional tests and realized that problem must be on Cubase, for several reasons:

  • Problem happens with different audio interfaces, I’ve used TASCAM 20x20 and a Focusrite Scarlett 2i4 and the result is identical: the track starts, the TMP BPMs start to drift.
  • Problem happens with different external destinations, I’ve used both Tone Master Pro and Headrush Core, and the result is the same.
  • There seems to be no correlation between using internal sync or other settings, and neither the “use system timestamp” which in some cases (Midi clock drifts and timing issues - #2 by Eran) seemed to fix the issue.

Does someone have any suggestions on where else to look?

Many thanks,

Raoul
