I believe it when I see it! (hear it). Who's gonna put their neck on the line and say it's fixed?

Where is Lagerfeldt?

I hope he's still using Logic Pro and is happy about the news.

Super pumped.. I hope everything works the way it is supposed to now. It's a little bittersweet as I've been all-in on Studio One for the past 5+ months and love it after 12 years with Logic. I hope Lagerfeldt chimes in.. would be curious to get his thoughts.

Well if you do this:
create track “audio 1”
create track “audio 2”

route track “audio 1” over “bus 1” to “aux 1”
insert latency inducing plugin “Linear Phase EQ” into “aux 1”
route “aux 1” over “bus 2” to “aux 2”

route track “audio 2” over “bus 3” to “aux 3”

insert plugin “Compressor” to “aux 3”
change side chain of the compressor to “bus 2”

put a identical drum-loop on both tracks

result:
audio 1 <-> audio 2 are in sync


So it looks like this part has been solved - at least for this scenario.
FYI
In my test LP Eq was reporting 53ms latency which was compensated for.
When I inserted a second LP Eq immediately after the first they went out of sync so there is a limit to the compensation. As soon as I removed the second one everything was back in sync again.
HTH,
Alan

Did you restart the playback after putting the second instance in the chain?

The update is not working for me at all. PDC still doesn't work. Even if I only insert one Linear Phase EQ, the audio is out of sync :x

well automation works fine? I can load DS1mk3 + ProQ3 very high linear phase and automation stays sample perfect.

I could make this insanity routing (all ProQ3 are Very High Linerphase - 17000 samples of latency (300ms) and everything is kept in time.

Pro-C2 which is sidechained is also in time.

I wonder why it's not working for me? I notice your on Big Sur. I'm still on Catalina, as is Alan Shields according to his signature above.

Yes, still on catalina and yes I restarted playback after inserting the second Eq.
It's working fine in the first scenario. I did use a totally blank project for testing not a template.

Is automation working for you? From reading some of the posts on the 10.6.2. release notes thread, it seems the problem is fixed for some scenarios, but not others. In particular, where a bus feeds a bus with a latency inducing plug-in(s) inserted, the delay is still not correctly compensated for.

I don't know why its working fine for you. I'm doing letter for letter exactly the same test and its not in sync.

I wonder what detail we're missing?

In the case of the side-chain I can say confidently that PDC is not working fine if an AUX channel is hosting the latent plugin which is feeding a side chain back to the other aux chain. Other people are reporting the same results as me.

I am mystified how its works for Alan...

Regarding automation I will try to do some tests tomorrow, but I think its crucial in testing to test for the same case of AUX channels being used in various ways with latency on the channels in different ways.

Me putting soothe 2 on a mixbuss to which all instruments are routed, but vocals go to stereo out. mixbuss goes to stereo out, too. sidechain soothe on the mixbuss with the vocals. Killer delay introduction immediately. Very disappointed. Big sur, Rosetta, old project.

have a look at this thread and see if the work around there can be used through your problem

idk what you guys are doing but i tried slapping soothe on a summing stack, fed by a BUS, and it's in perfect time. Automation also seems to be in -perfect- time no matter what i do.

The only thing that doesn't work well is if you have a sidechain processor on bus and you add a latency-inducing plugin after. Also Bounce in place.

Did you use soothe on side chain mode?
