Cassetto/Procession timing issues.

[AtomOfScent]

Cassetto/Procession are a few of my favourite instruments but I find I'm using them less due to annoying timing issues.

The sequencer MIDI in procession is always late, and there's similar issues when using the arp in Cassetto 1 or 2 (I assume it's the same in similar instruments).

Checking in my current project at 95BPM the renders are usually around 40ms late but not always (sometimes 80 or 160ms). When a section loops sometimes the timing goes completely off. The amount of the delay seems relative to the tempo.



I'm using Reaper 6, Win10-64 and the issue is the same on multiple computers and with Kontakt 5 or 6.

I'm wondering if anyone else has this issue and might have a solution?

Thanks.
