Fact or Fiction: Too many instances of a plug will degrade the audio?

Fact or Fiction: Too many instances of a plug will degrade the audio?

I read once that running too many instances of one plugin can result in degradation of the signal...

I mean, it makes sense because there is only one plugin in the folder, so to imagine over 30 tracks being processed all independently by one plugin seems like a stretch.

Can someone with plugin coding experience chime in? How does a single plugin process multiple audio files simultaneously and independently?

And has any experienced any plugins starting to sound like ****e after using too many instances?

I've used the SSL channel on every track when it first came out. It was the fastest ITB mix I'd done since I can recall and it sounded great. Not what I would consider degraded...

Maybe it's only certain plugins that do this...

It's late, I'm low on blood-THC, and so I'm thinking too much.

It's all separate. Don't worry.

I read once that using too many instances of a Neve plugin will result in low mid mudd build up. heh heh (sorry, I couldn't resist.)

No. But I've had many plugs sound like sh!t after one instance.

I'm just curious now... I've had my morning coffee and I'm ready to think again.

So, any developers willing to explain how a plugin can process 100 tracks independently and simultaneously?

With the proviso that I'm not a plug developer (one SynthEdit plug does not count, I think, right?)...

If it's coded properly, there should be no problem, assuming there are the resources available.

There's only one program file... but the host software loads multiple instances of it in ram separately, which then all run as independent programs, with their own memory spaces, etc. They essentially don't even know the other instances exist.

That said, if a plug is poorly written it might be possible for it to create problems for other instances of itself, though I think they'd have to go out of their way to do that in such a way that it didn't cause systemic problems, besides.

And, of course, a single instance of a badly written plug can bring a DAW to its knees. Some DAWs are more resilient/robust than others, of course.

I think this is on track. Thanks.

The same way eight cooks, each with a copy of a single recipe, can as a group bake 100 cakes an hour. If they hurry and can crank 'em out fast enough. Or four or two or one cook (but they have to be fast, and they have less time to keep the kitchen clean and brew a pot of coffee.)

But there is only one .dpm cook, and 48 stereo recipes!

For this you need Lucille Ball.

Unless the plug-in is written in an unusual manner, every instance is separate.

Some plugins that use DSP cards might do things a little differently, but unless the plugs are designed to do something behind the scenes like sidechaining or a rewire type setup, each instance should always be totally independent of the others. There's no difference, technically, from running a different plug on each channel.

Of course, if a plug has a distinctive sound, that might cause some stacking of some frequencies, etc.
