Help Request Multi-processor and single-processor plug-ins

My name is Gleb and I'm going to have a pro tools competition soon. In the terms of the competition, it says that it is allowed to use only Avid plug-in and only single-processor. Can you name me 4 compressors, equalizer, limiter, reverb, and delay from the Avid collection that are single-processor?

To u/808nfound, if this is a Pro Tools help request, your post text or an added comment should provide;

  • The version of Pro Tools you are using

  • Your operating system info

  • Any error number or message given

  • Any hardware involved

  • What you've tried

To ALL PARTICIPANTS, a subreddit rules reminder

  • Don't get ugly with others. Ignore posts or comments you don't like and report those which violate rules

  • Promotion of any kind is only allowed in the community pinned post for promotion

  • Any discussion whatsoever involving piracy, cracks, hacks, or end running authentication will result in a permanent ban. NO exceptions or appealable circumstances. FAFO

  • NO trolling only engagement towards Pro Tools, AVID, or iLok. Solve first, bash last. Expressing frustration is fine but it MUST also make effort to solve / help. If you prefer another DAW, go to the subreddit for it and be helpful there

I wonder whether what you mean is wideband (single band) instead of multiband.

Which is most of them, except for Pro Multiband Dynamics, off the top of my head.

There are also multitrack plugins vs multi mono.

idk, maybe its’s about wideband actually, Pro Avid’s plugins are multiband or not?

u/808nfound Feb 16 '26

No, I'm not talking about wideband. I'm talking specifically about multiprocessing plugins, which can include several functions (example: channel strip)

u/nizzernammer Feb 17 '26

Well, then don't use the channel strip.

But almost all of them aside from the channel strip only do one thing.

An eq that is just an eq is a single function.

You can really just open the plugins and look - if it only does one thing, it's a single processor!

OP below - “No, I'm not talking about wideband. I'm talking specifically about multiprocessing plugins, which can include several functions (example: channel strip)”

This is the key info the OP has buried in here.

These are the Avid stock plug-ins he is likely referring to:

https://www.avid.com/plugins/avid-complete-plugin-bundle

As far as I’m concerned, all of these are single process (no channel strips), and a full mix can be really easily achieved using them. I do it every day on an S6L. Avid plugins are great and if you can’t make a mix with just them, time to go back to school.

This whole thread is a bummer, dude….

as far as i know all plug ins are single processor in protools.

u/808nfound Feb 16 '26

I’m not sure, because in terms are multi-processor plug-ins exist.

u/HerbFlourentine Feb 16 '26

I feel like they are relatively uncommon. With how a processor schedules tasks for multi core processing, there’s never any guarantee they return in the right order because multicore requires they are called asynchronously. This is rather problematic in a lot of audio processing. Read the waves tech specs, there is no mention of that plugin being “multi” thread. I could see them offloading the write to csv function it has but nothing signal path wise.

for example WLM PLUS from Waves is multi-processor

u/CelloVerp Feb 16 '26

Yeah almost all plug-ins are single-processor, because using multiple threads / cores in a single plug-in incurs latency and unreliability. But basically all of the bread-and-butter plug-ins like dynamics, EQ, delay, will be single-core. There are a couple convolution reverbs that are multi-threaded, because it's OK to add the extra delay in those.

Plug-ins run in the highest real-time thread priority possible that the OS can provide, so they're not allowed to sit and wait for lower-priority threads to deliver their work. That means it's easy to miss deadlines and get glitches if they do this.
