I Intro
You want to run more plugins, master your tracks in on the fly and have logic perform without interrupts or system overloads.
How do I tune Audio Settings to get the best out of my system?
01 How macOS and operating systems in general handle multiple threads and assign workload to multiple CPU Cores. We will discuss Processor Affinity.
02 CPU load demonstrations on an 8 core Apple Macbook Pro M1 system and show how to measure the Firestorm and Icestorm CPU Loads.
03 Benchmark a real audio session for CPU load with standard Logic Settings
04 Overload the system by adding hungry plugins that chew out the cores.
05 Tune Logic settings to get more out of our system and run a session that would otherwise fail.
06 Conclude and summarise how to get the best out of Logic for complex session playback. Talk about the relative performance of the Macbook Pro, Mac Mini and Macbook Air versions of the M1 system for Logic
Notes
Program threads are allocated to CPU cores by MacOs
1. Affinity groups allow pooling of threads that would want to share L2 Cache for code and data interaction without cache misses and subsequent memory management churn.
2. Assigning application threads to different affinity groups will suggest to the OS that they could/should be allocated to different cores if available. This is load spreading and is managed by the MacOS scheduler depending on available resources.
The Thread Affinity API is introduced here:
developer.apple.com/library/a...
02 8 Core Demonstration on M1 SOC System
M1 High Performance group (P cluster) is made of 4 “Firestorm” Cores and maxes out at around 14W for the group. The efficiency group (E Cluster) is made from 4 Icestorm Cores running 1/4 of the L1 and L2 cache sizes when compared to the Firestorm Cores and with lower maximum clock speeds. The Icestorm E-Cluster has a maximum power drain of under 1.5W.
M1 machines share L2 cache within the cluster (12MB for the P-Cluster) so the overhead of cache management when migrating processes between different cores should be minimised.
Overall CPU util is based on the idea that all cores are equal. Which they are not. The “yes hog” has dominated the High-Power cores but we will report this as 50% util. We have only played 50% of the cards in our hand but we have gone in hard early the strength we have left in hand is weaker. Its 50% of the cards but not 50% of the power we had originally.
03 Benchmarking real audio with Logic
There is no one-to-one obvious relationship between the Logic CPU bars and which core will eventually run the affinity set. I have looked for one. Feel free to comment if you have more insight.
Clearly in the default config of only using the high-power cores we are limiting to 4 affinity sets.
The CPU bars could be viewed as the “intention” Logic has about spreading the load. What happens beneath is down to MacOs.
05 Tuning for better Logic Performance
A. Increasing IO Buffer
size has little effect on playback performance. In live multitrack capture I max it to 1024 (Samples). This has no measurable effect on logic size in memory. 1024 samples of 24 bit audio is 1024 * 24 / 8 = approx. 3KByte per track .. Nothing.
B. Process Buffer Range
Increases the size of Logic in memory 4.18 GB (small) 4.36 GB (large) say 200MB in my case.
Performance load measures are not obvious here but will be more so when system is at limit with all cores in play.
C. Mutithreading Option.
Default logic behaviour is to hide some thread headroom for the overhead of recording live tracks and/or playing live input to software instruments. The Performance monitor bars are hence showing something slightly less than Logics full ability to apply load to the system.
In particular I am seeing better logic thread headroom when BOTH the process buffer range is increased AND the multithreading option is set to Playback Tracks Only.
06 Conclusions
Logic limitations are based on peaks in mix engine CPU utilisation and have been shown to be related to dynamic audio routing. Since routing may be turned on an off through automation, Logic CPU load in real time is not constant and may fluctuate.
M1 Mac Mini has active cooling also and it doing to be on a par with Macbook Pro M1. MacBook Air M1 will perform well with Logic as CPU requirements will not have the highest of thermal profiles.
Plugin load and performance in Logic is made better by the allowing all Cores to process load via the Processing Threads option. Further improve CPU headroom and performance by setting the Process Buffer Range to Large and the Multithreading option to Playback Tracks if your session is in mixdown only. 
Наука
This is one of the most educational videos on Logic I've seen. Not only have you demonstrated how well it runs on M1, but you've also taught us a bit about how Logic Pro actually handles CPU loads and why! This is very very crucial! Thank you very much!
That is very encouraging. Thank you! I was really upset that this thing was over 30 mins but I wanted to keep the educational content in. It's my background! I need to be faster and I need to script better. If I had a classroom in front of me, my head goes into another mode and I say everything in a better way. The camera freaks me out.
@@MarkPayneAudio It must've been the wine that slowed you down!
exactly that! Thank you @Mark Payne
@@MarkPayneAudio i’ll tell you, i felt the video was pretty solid, Mark.
Definitely NOT boring or too lengthy.
even if it had been, one always has the option of increasing the video playback speed.
Your diction and script fluidity is really good enough for me to having put this on 1.75x and still having been able to follow along quite fine.
What a solid video and..in the end..somewhat of a tutorial .
thank you very much
subbed !
cheers from Portugal
Mark, I’m a 25 year old aspiring audio engineer. This sir… is the EXACT kind of content that I need. I’m so sick of the amateurs giving faulty information because of faulty testing. Now I have a so much better idea of how to run more plug-in’s 😏👊🏼🙏🏻🙏🏻 Great stuff my friend. Please don’t change and please don’t stop!
Best M1 chip review for music I've seen! Thanks.
Glad you enjoyed it! What are you running yourself?
I’m running intel MBP for mobile at the mo, just waiting till the 16inch comes out before I upgrade. It’s looking promising so far. Hopefully it will replace my desktop as well performance wise.
@@MrWaightyboy The 16 will kill pretty much everything, I am sure of it. I like the baby 13" format so I am happy anyway. But I will be tempted for sure! I just hope its a long way away!
@MrWaightboy I wouldn't call it a review. I'd call it an interesting computer science approach to Logic and the M1. I'll consider an "M" chipped Mac once I find plugin compatibility more acceptable. I am growing tired of Apple innovating faster than 3rd party vendors can respond.
That was the BEST Logic Pro video I've ever seen. I learned so much from it. You're so right about all those hypothetical "90 tracks open in Logic" videos not addressing actual real world usage. Your explanation was clear, concise, and without the usual 'hype' that others add. I have a much better understanding of how Logic works as a program within Mac OS. Thank you!
Wow, thank you! Comment much appreciated. It took a good few days to come up with a set of tests that could show what was going on. Its good that people notice so thanks!
Just love how you ended the m1 benchmark pissing contest for good. Wholesome.
Boom bang-a-boom! :-)
"Wholesome" is my new goto word!
I honestly watched this video a few times. Its not because i don't understand what you were saying but its because you explained it so well that its worth watching it again.. Thank you so much!!
Thank you also!
Saw this about a year ago but, now that I have just got a Mac Studio, with M1 Max it has suddenly become very relevant to me. Many thanks Mark for all that you do for the Logic community. It is very much appreciated.
Great to hear! Thanks!
I had an absolute pleasurable time watching this video. I want to thank you very much for the quality, great education, effort and care you provided in this video, Sir.
Finally someone that expalins very well a real Logic CPU Stress Test.
Haven’t watched a 30 minute video in years. This is some seriously good content, love the effort.
Thank you so much for this video. You’re way more informed about how computers actually work compared to any other person I’ve seen on here doing ‘similar’ videos. This is so much more valuable than knowing if you can run 80,000 instances on Space Designer spread across 400 tracks.
you sir have made my day... I've been looking all over the internet for these answers. I cannot thank you enough.
From a software engineer (I started my career as a audio engineer and eventually started writing software) -- @Mark Payne it makes me so happy that you know and think about these things. This is so well presented to this channel and gives a great insight into how the hardware and software work together in a practical application.
Thanks for testing this all and showing it to us. Very interesting to watch, and it will save me the time while setting things up when my M1 mini arrives.
Thanks for watching!
This video series is a treasure trove of hyper-valuable information that I have not yet seen. The concepts of I/O buffer vs process buffer, multithreading & thread affinity were all explained so simply.... I just can't believe this is all available for free on RUclips. Thank you!!!
Welcome and free :-)
This is just an amazing explanation, and also educational on general CPU and how programs work. Super amazing
Really enjoyed how you explained how everything works. Best video I’ve seen on the subject
Great content! Love that deep diving into all that details and background stuff :)!
Yes, I try and understand how it works then you can predict what it will do!
This video is a Masterclass demonstration. I'm 62 years, have a lot of experience with big client/server environments on Windows, Mac and Linux. I followed lots of official training but this were the best 30 minutes of giving information and how to demonstrate it. Well done, Mark.
That is very encouraging. I was a computer systems support engineer and educator for Hewlett Packard till the mid 1990's when I started SFL Group. That is where this kind of delivery was learnt I guess.
I’ve learned more about my new computer than I bargained for. Thank you for this sir 😊
Happy to help!
This video is the most valuable I’ve seen in years. Thank you for explaining this Mark!
Thanks!
Wish I could hit the like button again. Great information here. I don’t see many people delving into the nitty gritty of Logic X the way you do. Thank you!
Much appreciated!
Brilliant! This stuff is super technical but you break it down really well. Thanks once again Mark!
Glad you liked it! I am trying... and learning :-)
I can't thank you enough. Once and for all, you made it clear and explained how and why. I went from crashing to 25% in the Logic CPU meter. Life saver!!! This is essential!
As others have already remarked, this was an amazing video. I also loved the touches of humour along the way. Thanks and keep up the great work!
Thanks!
What a great video, the length didn't bother me at all. I was writing an essay for uni and every time I was taking a break I was coming back to see the rest. Next time I'll have a glass of wine for myself and enjoy your content properly. So glad I found your channel
Thanks John!
Amazing! whether M1 or not, this is by far the best video i have seen that actually digs deep and gives you the understanding to troubleshoot effectively when one repeatedly sees the dreaded “Logic’s death certificate” on your screen!
Thanks J. I appreciate it.
So glad I came across this video. I've been trying to get a full comprehensive guide on this. Thank you
Welcome!
More Clear test could not exist!!! Thanks for your sharing performance!
I've been composing in ableton for a few years now but I'm a fairly new student just starting to learn about audio production and studio work. I'm looking at getting a mac for the first time ever since using logic at school and love its simplicity and workflow, and your videos have been the only ones I've found that are comprehensive and factual enough to actually assist me in buying one, your combined audio and tech knowledge are a perfect combo for this series! So thanks for all the effort it really is an enormous help and greatly appreciated! ✌
Thats great to hear. let me know how you get on!
I got 1:42 in a already blown away by this. Your presentation style is informative and reassuring with out being over complicated. Thank you for making these videos.
Wow, thank you!
Whoa....next bottle of wine is on me! Phenomenal video and a great explanation of what is happening, and what you can do. So right about the stress tests. Thanks so much for this, cheers.
Glad you enjoyed it!
This was a really great explanation for what is happening behind the scenes on the M1 with Logic Pro. The way you explained it made a lot of sense. Thank you for the breakdown and the insight on the best settings. Great job.
Glad it was helpful!
You are a good teacher - I learnt a lot from this. Thank you!
You're very welcome!
Thank you for taking the time to explain this. I much prefer this to just seeing the settings with no info as to why. I am subscribing based on that alone.
Understood and thanks for the sub!
I’m not completely ready for this video yet but I can’t stop watching. :)
Great job Mark! 👍 I have to compliment you on finding the perfect balance between geek and layman - probably one of the best executions of this I’ve seen on RUclips. I also highly appreciate that you don’t hype yourself, your services or social media presence every 30 seconds! Congrats on figuring out how to do it right - keep up the great work 😊
Thanks!
FINALLY!!! Comprehensive knowledge on a subject and system that is unfortunately oversaturated with amateur analysis and click bait. Mark, this was definitely one of the most insightful rundowns I think I've seen from anyone re: this subject. As a professional musician using these platforms in actual tracking and mixing scenarios, this has shed so much light and professional perspective that many have been actively searching for on the internet. I don't think there's any need to apologize for being so detailed and thorough. I really enjoyed your thoughtful insight on these very necessary considerations when using a Mac & Logic. Bravo to you, Sir! I am definitely subscribing to your channel. Looking forward to further insight and perspectives. Cheers from Toronto, Canada!
This chap knows his stuff. Thanks again Mark.
Thanks Eden.
This is fantastic! I've totally optimized my iMac after watching this. Thanks for the tips! Subscribed!
This video is so informative! Thanks so much for taking the time to go into such detail for M1 users.
This is genuinely remarkable - I'm really excited to see what the M2 has in store
That is going to be a killer system but I love this little 13"!
@Alec Nichols My guess is September... but really I have no real idea. I think the internet is full of people that like to guess this stuff!
Hi Mark!
Great content, keep it coming!
Cheers from Brazil
Muck love from the UK!
Finally an in depth discussion with real world examples of running hungry plugins on an M1 Mac and how to optimize the system & software. Thank you for this!
You are most welcome!
Great demonstration video on this topic, very well done Sir!
Amazing video! My i7 3.2gHz 6 core Mac Mini (2019) with 64GB RAM was choking on Logic, even though a lot of my plugins were UADs, running on 20 cores of UAD processing! Your tweaks just freed up about 50% more CPU headroom for me, and my problems have vanished. Even when not crashing, the audio "sounds" more stable (might just be my brain... LOL). TOP MAN! THANK YOU!
thank you very much . this is the best ( to be very honest ) m1 logic test review i have ever watched since it was released ( i have given a sub and and a like )
Much appreciated!
The only video I can really hear M1's fan running! Cool!
You have to push pretty hard for that to happen!
My friend, you have no idea how useful this video has been. Thank you
Glad to hear that!
Thanks for this information. Very difficult to come across some deeper reviews and tips on YouTibe and this is definetely not the typical superficial review on these laptos. Subscribed! 👏🏻
Glad it was helpful! I have a new video coming where I show 8GB Air vs 16GB Pro examples running home and office productivity tools, Logic and Final Cut. The thing is just short of an hour long. Maybe I am making a mistake doing things in this detail ?!
@@MarkPayneAudio I would watch for hours, were they as informative as this! SUBSCRIBED!
Impressive video Mark. It requires great skill to make something complicated much easier to understand. I rarely subscribe to anything these days as I already loads of subscriptions but your videos are very different to the norm. Hence I’ve no hesitation to subscribe and look forward to learning more from your expertise. Thanks.
Thanks for the sub! I appreciate your discernment.
FINALLY the tutorial i've been looking for. I run logic pro more like a modular synthesizer, I route and side chain everything left and right and I get error syncing midi and system overload all the time and this has finally given me some insight on which processes are heavy on my machine. Thank you very much!
Most welcome!
Excellent video that encapsulates all of the important questions and answers i've had difficulty finding for years!
Glad it was helpful!
Mark, Thank you very much for this very learnful and interesting video. As I am considering a M1 Mac mini + Logic Pro for studio recording and mixing, your video gave me the confidence to move forward in this direction.
FYI: I liked the combination of your IT background merging with the pragmatic approach on getting the best out of your audio gear. It's the same for me as formerly being a professional drummer and recording engineer, but now run an IT company (so sort of the other way around opposed to your career). I have subscribed to your channel. Will be following you. Rolf (The Netherlands).
Excellent!
Thank you for the tip on how to maximize the cores! I was getting so many system overloads prior to this with all of my old third party plugins. I was about to return the M1 haha. This definitely saves it.
Great to hear! Saved!
same here. This video is useful 8 months after it was issued and it is unbelievable that this knowledge is not available on the apple support or on the regular RUclips channels
Best channel I’ve seen in years! So much useful and informative stuff. Helped me a lot in deciding what to buy for my studio Mac. Thanks a million! 🤘🏻🎸😎
Most Excellent!
Affinity explanation and clarification of how loads are allocated really helpful, big thanks.
Many thanks!
One of the best videos on Logic and M1 on RUclips! Thank you so much :)
Wow, thanks! I appreciate the feedback. Makes it all worthwhile!
It would be very interesting if Apple would optimize Logic Pro to be able to use available GPU cores for extra processing power, particularly as they release more powerful GPUs in the future. If Apple were to create a new plug-in format that uses their GPU as a separate processor for running plug-ins, that would change the game for real time tracking through plug-ins in Logic Pro without the necessity for extra external hardware.
My money is on the leadership at Apple not re-architecting Logic pro to use the GPUs to great affect. They have chosen a very simple way of scaling with a multicore CPU. It is mostly the OS's problem to divvy out the work between cores without sw architectural changes within the application. It would be a much larger problem for the Logic pro developers were they to rearchitect the application to use GPU for the computation tasks that are currently handled by the CPU. It can certainly be done, but don't envision them doing it.
@@garysolomon3845 yeah, I agree with you. Interestingly enough, another company has taken advantage of the gap in the market.
Check out GPU Audio. They already support running VST3 plugins on Nvidia GPUs, and within a week, they will officially support AMD GPUs. In 2023, they will support Apple Silicon, and they intend to expand support to cover different plug-in formats, beginning with AU and AAX.
If they do not have a patent on the concept, Apple needs to jump on board, but I doubt they will.
@@robertsimpson5801 i did a consulting gig for a few years at NVIDIA after retiring from Intel in 2012 and i can tell you that NVIDIA did a TON of heavy lifting to enable general computes on a GPU core. They invested heavily in enabling the development community with great sw tools, and a compiler to help designers port their massivly parallel computing solutions to Nvidia gpus. I just don't see the "geniouses" at Apple even knowing what is required for industry enabling no less take on anything that involved.
Incredibly well done. Clearly explained and demonstrated. Thanks!
Beautiful video , very glad to have met you on RUclips ..:)
Thanks for coming
This is one of the most useful Logic Pro videos I have ever seen. Thank you, Mark, for sharing this useful deep dive into Logic’s CPU usage. (Disclaimer: I work professionally in the music business, composing and engineering music, plus engineering post-production. My colleagues and I mostly use Logic Pro, and Pro Tools in combination. We can all benefit from Mark’s very helpful video!)
Thanks Melissa.
I did play around with these settings a bit when I first got my m1 Mac mini. Wasn't sure if it made a difference but I wast utilizing for playback which makes a big difference. I always noticed that stereo plugins or using in the form of studio is a memory hog. I can add the same plugin on a mono track barely uses anything then applied to the master buss and bam cpu goes up. Thanks for this video. Now I understand what's going on and how to squeeze more plugins natively. I do have an Apollo 8p with a octocore satellite that helps a lot and so far I haven't got into a situation like this but great info. to know. Take care.
wow. I'm speechless. I wasn't expectin that kind of a deep knowledge. This video is sooo informative. Thanks a lot
My pleasure!
i have used logic for so many years and this was the most educational video I have seen on setting up logic for best performance
Excellent!
2009 mac pro. Pushing the limits. 😂
Keep on keeping on! 2009! Right now, I would go back there ;-)
Hi , Thanks for your vid , Does 64 bit summing take more processing power given that , that summing option is open to use more ram than 4 gb ? What happens if we fiddle with that preference and make it 32 bit summing ?
I did try that previously and I found that it made no difference to the processor load.
Very interesting and educational video on Logic Pro X running on the M1. Thank you for sharing this useful information with us!
You Sir are incredibly intelligent and explain things so perfectly well. I tip my hat to you in admiration. Truly.
Will it make a difference on CPU performance when plugins start converting from Intel to Silicon?
It will all just get better and faster IMHO. The real issue is the "half way house" . Rosetta Logic on Rosetta Plugs is all good... reliable and at some performance penalty compared to where we will get to. What I don't fancy is M1/Native Logic with say 50% intel plugs and 50% M1 plugs. That will be messy.
This drooling old man is kinda stating the obvious isn't he?
Thats funny! Apparently if you read the comments here and the hit rate on the video, it would appear to be helpful to many. This drooling old man is just going to pop across to your channel to see what your videos are like.
Oh look, what a surprise, you don’t have any.
Great video! Finally a Video with a professional requirement and the right background informations. Really rare on RUclips these days. Most guys are talking about things they do not understand and these guys are giving tips to those who are reliant on - Really dangerous. But good to see that there are some professional colleagues left who are sharing their knowledge ! Great stuff
My pleasure!
This was excellent and some great tips for running my new M1! Thankyou!
This is really a worth-while review of Apples M1 series for audio production since its inception back in 2020. We've All been clocking the M1 in every format since its release.. & This 30 minutes deserves a replay. Time well spent, Thank you Mark Payne ! Anything that is well done is done forever. Cheers !
Thanks Bogle. Much appreciated.
I have gotten more out of this than basically any other Logic Pro lesson/RUclips thing I’ve ever seen. I took notes when watching! Thank you so much. Grabbed a whiskey to drink along with you!
Great to hear!
Hey mate. I've written about 500 songs in my life, and now I'm becoming a professional producer. And can I just say, your no bull, completely logical and linear approach to explaining intricacies that someone like me who used to just jump into a project and make up an idea would have no hope of knowing.... Flippin' brilliant video mate. My band is not going to flay me after all thanks to you hahahahaha. Cheers from Aus
Manny thanks!
Brilliant explanation of complex stuff that even a tech dummy like me could understand. The mark of a man who really knows his stuff. Subscribed. Thanks.
Glad it was helpful!
Great vid! Explanations made sense with actual live tests that prove what is being claimed.
Glad it was helpful!
Kudo to this perfectly explained video! I enjoyed every minute of it and got some understanding about how Logic processes the CPU load! Cheers
Glad it was helpful!
Outstanding info 14 months later! Thank you Mark for all the work/time you put into this. Found it 'cause I've just rec'd my 14" MB·Pro M1 Max 10-core. A bit surprised that an operation like re-enabling Core Audio, which reloads all plugins, is rather slow (but I realize this may not be a useful benchmark). Anyway, your suggested playback settings for M1 are most welcome. Toasting you with a glass of Malbec. Cheers!
I love this video. Very good stuff indeed, infact one of the best viedos on the subject I´ve seen. Highly appreciated. Many thanks Mark..and cheers! :)
Wow, thank you!
I've been considering a MAC mini M1 for a small project I'm starting. I'm used to Logic as a DAW. You've covered a lot here. This has been well worth watching. Well done! thanks
Great to hear! Lets us know how you get on!
@@MarkPayneAudio may take a month or so to get totally operational, but yes, I will!
Very nice content, both informative and well articulated, thank you! Definitely sticking around for more :D
I'm a bit late to the party, but may I add you're a figurative life saver! I wish I had you as a teacher for ALL topics - fantastic job Mark!
That Info is what i was looking for.
Thanks a lot for that
Glad it was helpful!
This isn't your usual RUclips self aggrandizing puffery. This is EDUCATION. Thank you!
You're welcome. I will consider your ideas for afuture video!
All and even more I needed to know about ‘how m1 and Logic are performing together’. Excellent video from a real red wine lover, right! :) !? Thanks and cheers man.
Thank you so much! - I've been struggling with "system overloads" so much on my M1 MacBook Air. I never thought to do some of these things.. I'm so glad I found this video
Glad I could help!
Thanks so much Mark, this is a really brilliant video, so well researched and presented. Fantastically useful.
Glad it was helpful!
I like the content and the way Mark is explaining - very useful and sympathetic! And a good reason for a glas of wine ;-)
Glad you enjoyed it! And Cheers!
This is one of those times when a quick RUclips search comes up trumps, real pleasure to watch and a reminder that I have a bottle of Jamshed awaiting me!
Loving that!
Thanks Mark. Very informative and helpful.
This vid was a life-saver for me, huge thanks Mark!
Welcome!
Best description ever for how cpu and cores work. Updating to a Mac mini m2 pro immediately with lox settings you have described. Maybe my acustica plug-ins will now give me a break - I do love them
I can't express how useful this information is to my situation. Thank you thank you thank you
I use the hell out of soundtoys little alter boy and it is an absolute cpu gobbler
this is golden, absolutely incredible video 🙌🏼
The fact that you showed the BSD manpage for sysctl raised my interest in your channel 📈 👍
Good stuff. I was a live engineer for many years and used ProTools with the Avid Consoles like the SC-48 and the D-Shows. I retired in 2019 and just joined a local recording studio here in SoCal, USA and we are using SSL stuff and Logic. Thanks for all the Logic Tips for this old man. Cheers
This is absolutely excelent. Thank you Mark, you've gained a subscriber.
Awesome, thank you!
Really good analysis, I run Logic on M1 so that was perfect. Thank you.
Great to hear!
Great video. Intro music is banging!!!
Glad you like it!
