Channel EQ and Limiter broken after 10.6.6 update?

It appears to be fixed in 10.6.9 I've updated older libraries with Limiters and they work as expected! Lesson learnt though to save an older version of FCPX before an update.

This does work to a certain extent. This just bit us with a project we have been working on for the past 12 months or so. It's a multi-year project so not updating is really not an option. We have several custom audio chains built to make it simple drag and drop. Updated our editing machine to Ventura and FCP 10.6.6. Opening this project killed our audio chains that were simply EQ, Compressor, Limiter and Multi-Meter.

I sent an Auto Save to another Machine with 10.6.5, along with the Audio Chain. Exported an XML and reimported into 10.6.6... This surprisingly fixed the audio, but all of the Motion Drop Templates we created no longer had content. This was easier to fix than all of the audio that needed to be redone.

Surprisingly this is not happening to everyone, as one of our other editors was able to open the project with no problem. We have some Waves plug ins along with Isotope RX Suite... so I'm wondering if one of those is messing with things.

I just purchased the Waves L2 Ultramaximizer limiter for $36 to make up for it. It gets the job done. This situation sucks, but at least it's a workaround if you're looking for a quick and affordable non-Apple limiter solution while they (hopefully) work on a fix for this.

Same issue on my end. All limiters are stuck at the following settings: Gain -18 dB, Output Level -9.9 dB, and Lookahead 1.0 ms.

Here's a gif of the issue:

Tom mentioned that with 10.6.6 a Library update is required. This may be a side-effect of that process.

Others have reported similar issues with audio levels with respect to audio presets.

Thanks for reporting it to Apple.

I am using 10.6.6, the new Pro Video download, and Ventura 13.4 (though this was happening before the Ventura update)

Any audio track with built-in Loudness filter is muted; any audio track with built-in Compressor is muted. If either of these effects are turned on then the track is muted.

And I was just about to render an extremely complex half-hour project...

Same here man! I just posted about it. This happened to me right before my video was about to go up and I had to "rough" adjust the audio. I had to spend almost two days to rebuilt the same audio effect that I built for my microphone and it's still not the same.

As you mentioned the update completely wrecked the limiter as well as Channel Eq and everything else you talked about in your post. Looking forward to speedy apple response to this critical/crucial issue. Looks like someone didn't do 'regression testing'

I just posted a question about this before seeing your post. Thank you. The same thing is happening for me since the update, and I've had multiple interviews where I had to totally redo the audio because all the limiter levels are wrong. It's costing me money because freelance projects I've almost finished, I'm now having to totally redo the sound levels. And I called Apple Care and they were absolutely no help. I'm so annoyed.

I'm glad I'm not alone with this issue. Here is my story:

I've had a preset (EQ, multipressor, limiter) which I applied to all the audio and then just made micro adjustments. So after I upgraded to 10.6.6 the preset was ruined, it was painful but ok, I had to remake all the effects and save a new preset. I though it was over but...

now I've applied my new preset and it started glitching again. It is super annoying. I have to do so much extra work now.

I thought it was just me! My limiter is broken. The gain is set at -19 or something, and even when I change it, it won't save it on the track... not sure what to do.
