Hi Pitchy,
Thanks for your update.
Please provide me with the download link to the clip via private message, once you’ve captured it.
The more detailed steps are visible and/or audible, the easier we can give it a repro within the team to evaluate the issue.
On a side note:
It might make sense to give the latency settings (Setup/Audio/Hardware Latency) a closer look, to see if they will contribute to better results when recording MIDI, before making use of quantization.
Hope that helps.
Best,
Lars
