Hi there, I know this sounds like necro-posting, but I’m facing the exact same issue you described here with Cubase 13 (MIDI out BPM are dynamic and messing pedalboard delay), and I was curious about other settings you played with to solve this problem, because for me checking “use system timestamp” didn’t change the weird behavior, I’m still getting drifts in the BPM of my external device.
Do you have any suggestion?
Many thanks,
Raoul
