Re: Multi mono - Singal generator out of phase
Of course it does not. Processing will be in phase between channels in a multi-mono instantiation of most garden-variety plugs (including Trim). One should not expect plugs with any form of randomized process (delays, reverbs, modulation) to be phase locked between multi-mono instances.

Re: Multi mono - Singal generator out of phase
If this wasn't already made clear:
A multimono instance is actually 2 instances, one on the right and one on the left. A mono track panned center is one instance routed to left and right. Two mono instances could very likely start generating a few samples apart from each other and therefor be out of phase at certain frequencies. One mono instance panned center should track phase wise across the spectrum. If it doesn't you should look a the rest of your session to see if you are routing through something strange.

Re: Multi mono - Singal generator out of phase
That's fun! The phase meter jumps all over the place. tbh, in the nearly three decades that plugin has existed, I don't think I'd ever instantiated it as multi-mono.

Actually I would expect an oscillator to be in phase too in the same way in a multi mono plugin on a modern system... |

Re: Multi mono - Singal generator out of phase
I don't get why you can't just use one signal generator and route it where you need it. You wouldn't have 24 separate sine waves if you were lining up a tape machine, you'd use one and route it accordingly.

Re: Multi mono - Singal generator out of phase

I’m not following what you are saying. Yes I mean oscillators. Generator is a synonym for oscillator, hence the name of the plugin. There is no phase coherency issue with using multi mono plugins. Two oscillators, however are not guaranteed to line up every time no matter what kind of channel they are dropped into. Rich said the exact same thing as an oscillator is microscopically randomized. Nothing I said contradicted him in the least. Some of the brightest minds on this forum have patiently and respectfully explained to you that your test is flawed. To test phase, one must use one mono oscillator routed to both left and right. I’m not sure what’s left to discuss here. Sent from my iPhone using Tapatalk

Re: Multi mono - Singal generator out of phase
Maybe the heading is a bit misleading. The original problem was solved but I got concerned and a bit puzzled by the way Multi Mono works.

So this confirmed exactly what I was worried about. Phase coherency is not guaranteed in Multi Mono plugins. So anyone using these in a multi channel setup in abscence of a proper Multichannel version should be cautious. And if I'm wrong by definition like you seem to think please provide some kind of refrence to what you claim about the internal algorithms in ProTools. addendum: I just found this in ProTools Reference Guide 2021.10. Anyone who knows about Ambisonics and the fact that the text address Multi Mono specifically might agreeI have a point: Quote:

Re: Multi mono - Singal generator out of phase
Omg.
THEY ARE NOT PHASE LOCKED BECAUSE THEY ARE TWO SEPARATE INSTANCES. (Read this six or seven times to really drink it in). Sent from my iPhone using Tapatalk
