Freeze Instrument track erratic

[daeron80]

Frozen tracks randomly have no audio or are very long with a little audio near the end. Happens about half the time. Anyone else experiencing this?

PT 2021.10, Windows 10 latest update, 24-core XEON, 64 GB RAM. Saffire interface.

I did a large orchestral thing recently using mostly Spitfire stuff. Wanted HWB=64 to keep latency to a minimum. CPU usage got dodgy/spiky with more than a handful of active tracks at a time, so I was doing a lot of freezing as I went along.

But I couldn't take the time to check that every single freeze operation had worked, so I gave up and used HWB=128, which allowed me to play the whole orchestra with no frozen tracks. But if a take has to be tight, you either slide the notes a little, use Realtime Properties to force it to play earlier, or quantize. Annoying, but quicker than dealing with silent frozen tracks.

Is it a bug or a system problem, you think?

Just me, but if I use freeze, I unfreeze before closing a session. If I want things to stay cpu-lean, I use Track Commit and leave the original showing but inactive. Yes, its more stuff on the screen, but it avoids any issues with freeze.

Commit is great once I'm committed. But I often compose in sections. I need to freeze parts that I will be adding more to later. And I may decide to rewrite at part or assign it to a different instrument. I don't want my session cluttered with committed parts that I'm not committed to.
