Unstable timing (jitter) of VSTi MIDI routed events

Looking into the MIDI timing of the internal MIDI routing now (Loomer VSTi to some other VSTi). I’m not familiar with Loomer. Could you share a little demo song here with us?

If there are other examples needed. I’ve upload a test song done with Xfer Cthulhu. I did compare Renoise with FL Studio, both with direct sound driver. In FL the note offset is the same, but in Renoise its jumping. This causing sometimes missing notes and the overall arp feels “swingy”. Have this issue with several arp VSTi’s like BlueArp, Cthulu and so on. And as far as I have experienced, it getting worse, when you use phrases.

(Top is Renoise and bottom is FL)

Edit: This issue can also causing stuck notes on song export.
