Ozone 5: glitching on Master buss, not on individual track
I'm having trouble running Izotope Ozone 5 Advanced in Reaper x64.
1) At low latencies, when the Ozone 5 module is in the Master buss, there's horrible glitching and drop-outs. However, when I cut-paste the same instance of the plugin on an individual mixer track -> no glitches whatsoever. What's going on here? It looks like it's the multiple receives that is causing issues for some reason. I don't get it because there's still just 2 channels of audio for it to process - surely the plugin doesn't 'care' how many tracks it's being routed from?
2) Ozone reports my total system latency as being in excess of 600ms! I find that very strange: my system DPC latency is around 20 picoseconds and Reaper reports ~1.7/2.5ms. All drivers are up-to-date and the system is optimized for audio (no antivirus running on the background, LAN disabled, all automatic updates disabled, processor at constant clock speed etc. etc.)
System specs:
Windows 7 64bit & Reaper x64 (latest version)
Intel i7-3820 @4.3Ghz
Asus P9X79 motherboard
RME HDSPe AIO PCIe soundcard
Samsung 830 128GB SSD (for OS & recording)
2 x OCZ Vertex 2 128GB in RAID0 (for samples)
NVidia Geforce ENGT520 Silent GPU
