DP 11 and Mac Studio Ultra underperforming?

[sayatnova]

Hello Everyone,

I am trying to understand something: I have a session in DP 11 that is now crackling and maxed out with a latest plugin addition, yet, my Mac seems to be only using a portion of the computers' cores? I am using a utility called Menu Meters to see the read and write activity of all the cores. I have many cores not showing really much activity, and only the first 4-6 show a strong activity. There is very little happening on the second half off all of my cores that I can see.

I do have a few tracks that have a lot of heavy-hitting plugins on them:6-10 in a row. I think I remember something about each tracks' plugin row was using a single processor, or something like that? It seems like DP is just using a few cores and not spreading the load over the rest of all of my cores? Is this a thing to be aware of? How do you mix, then?

Again, it is odd to hear stuttering and glitching after a processor intensive plugin is added to the session (that was working fine just before that...), and see only half of the actual computer cores being used!

All plugins and DP are up to date. All are AS ARM versions.

Anyone have any suggestions?

Thank you.

Read this and test to see if it might be a plug-in issue. A lot of these are.

You might be overloading one core in which too much audio is processed.
May be you should Try
processing the audio in two separate tracks.
Say.. 3 plugins in one track send the audio to another track with the other 3 plugins, so more cores are used in the heavy lifting..-Just guessing this might work.
or increase the buffer size.

+1. Bounce those bad boys.

Thank you, Everyone, for the replies.

The buffer is already the highest it can go: 2048...

I think it is just overloading a processor core, then, since DP will return to normal once I removed the last plugin that choked it.
I guess this could be checked by adding that same plugin to another track that has no plugins, and see if DP still chokes?

So, if it is this, how do I know which tracks' plugins are overloading the system? Is there a meter for plugin combined CPU loads on each track?

I guess DP does not know to spread the load to different cores like a UAD Satelite?

Asking to learn. Thank you.

I answered that question in another thread where I show you how to test it. I linked to it in my earlier post.

You should also have Apple's Activity Monitor up. The top window shows combined single core performance only so 400% on a 16 core machine is really 25% overall — as you will see on the bottom window.

I’m having similar issues, same set up, same Mac and DP version. I had a very fast woodwind run on an instance of Musio VI.

I had a 16th note run in an up-tempo session only using one loaded instrument, and it was maxing out the Mac, slowing down the tempo drastically and distorting the audio output, while clipping the processor meter. At the highest buffer setting.

I turned off every other channel, and disabled all other plug-ins, even the master fader. Just had the one Musio instance, active (routed to a hardware output) and the associated MIDI track. The machine could not handle that short 16th note run.

So, I changed plans and simply pulled that track off of my Yamaha Montage M8x-a hardware sound source.

It worked perfectly. The sound quality wasn’t quite the same as the Musio woodwind instrument, but it sufficed.

The Mac ultra could not handle the virtual instrument load of that fast run at that quick tempo- it was brought it to its knees. Even at the largest buffer setting.

So wondering if I can do anything to improve that situation. I need to try that again with my activity monitor meters visible.

I assume with everything else turned off in the session that Mac would know how to spread that load across the entire processor core group. One should never assume I guess!
