Deesser Causes DR 14 to crash.

Like the title says.

I have tried inserting IK Multimedia's multiband deesser on an audio track and it works just fine while I'm still in the Fairlight page, but when I switch back over to the edit or color pages, playback immediately slows to a crawl, begins to stutter and then Resolve crashes within a few seconds.

I downloaded a freebie deesser (Lisp) as a test to see if it was IK's fault, but experienced the same behavior.

What could be going on here? Does DR hate deessing or something?

Yeah, I know my system is way lacking in the graphics department. But I have done projects that push up against the wall much harder without this issue.

I've even had one with two EQs, compressor, limiter, expander/ gate, RX elements AND Acon Digital noise reduction as well as a convolution reverb piled on top of each other.

Crickets?

Is upgrading or testing DR 15 possible? A lot changed in Fairlight with the new version.

Like the title says. De-esser Causes DR 14 to crash.

I'm not a fan of the IK Multimedia stuff, but I have used them and they should work.

Try 15.1 and see if that improves things. I have tested the Waves plug-ins and a few others and they seem to work as they should. Don't forget to post all the tech details for questions like this: What OS? What hardware (CPU, GPU, RAM, I/O)? What type of source files?

Also, DR 15 now comes with its own de-esser which is most likely more stable. From the Blackmagicdesign media release:

"The Fairlight page now has a complete ADR toolset, static and variable audio retiming with pitch correction, audio normalization, 3D panners, audio and video scrollers, a fixed playhead with scrolling timeline, shared sound libraries, support for legacy Fairlight projects, and built in cross platform plugins such as reverb, hum removal, vocal channel and de-esser. With DaVinci Resolve 15, customers no longer have to worry about audio plugins when moving between Mac, Windows and Linux because the FairlightFX plugins run natively on all three platforms."

My system (see signature) is barely adequate as it is. From what I understand, 15 is even more demanding, so I have been hesitating until I make suitable hardware upgrades. They are in the que, but likely to be down the road a ways.
