Logic 9's UI extremely laggy - any fixes?

I've been a pretty happy Logic user since 2004, but lately version 9 has been really cheezing me off. It seems that whenever I'm playing my current project, the user interface becomes completely unresponsive to key commands and mouse clicks, which will be delayed for many seconds, or ignored entirely.


This is a fresh install of Logic Pro 9.1.4, 32-bit, on one of the new Mac minis (dual 2.7GHz i7, 4GB RAM, stock 500GB hard drive), with a PreSonus FireStudio Project. However, this was also happening on my previous system, a 2008 15" unibody MacBook Pro. It was happening a little bit on Snow Leopard but it's gotten much worse under Lion. My MacBook had aftermarket RAM (8GB) and an aftermarket SSD, but everything in the Mini is stock.


It's happening even if I only have one or two tracks, although it seems to be worse if I have any of the various metering plugins running and open, or ChanEQ with the analyzer turned on. I wonder if maybe those plugins aren't handling UI updates correctly, or something.


Just to be clear, I have absolutely no third-party AudioUnits installed, and it's neither a CPU nor an I/O issue (both gauges are pretty much empty, and Activity Monitor shows Logic as taking about 10% of one CPU), and yet it takes anywhere from 3-10 seconds for a simple mouse click to go through.


This is getting EXTREMELY frustrating, especially since the lag seems to always happen at the worst moments (i.e. I'm trying to turn down the volume on a track which suddenly got really loud, and the lack of responsiveness means my ears get blasted and I have to take a break for them to recover before I can start mixing again).


Has anyone else been experiencing this and found a workaround? Is anyone at Apple even paying attention to these issues? I feel like it's the same problem that was being discussed in this thread, which was never resolved: https://discussions.apple.com/thread/2396951

You know what guys now that u mention it it, yes, while I run 2 instances of starcraft 2 at high detail while running logic , I notice my metering starts to get choppy. Cmon apple get moving with a fix this is unacceptable!



Are any of use REALLY using 3 spec analyzers in high res at same time? I have never used any setting other than low anyway...


Be reasonable on your hardware 😉

The Logic update seems to have cured the GUI lag for me running ML 10.8.2 on my Mac Pro mid-2010- at least with a "light" load of 3 or 4 EQs open and analyzing at normal res. I can now change the EQ on the fly without any lag in response, and start and stop playback without a problem- all of which was impossible before the update.

Test done. Three days of HARD work with the new update installed on Mountain Lion, in which should be the the normal state. The fact is : LAG IS NOT GONE. It's better than before, but not as good as it was on Lion or Snow Leopard. At least it's usable, if you take care of all those plugins using analyzers. Don't expect too much improvement, with 3-4 analyzers enabled (or any other animation inside a plugin) everything stars to get laggy again.


Anyway I'm a little bit disappointed, because the looooooong wait for Logic X continues.

after a promising enough first week or so with 9.1.8, yesterday I experienced the annoying lag issues.


I'm so over this I can't be bothered, to be honest, to report in great detail what happened.

Sorry.

Ive been using Logic for years.

My studio is set up well.

I think I'm pretty IT savvy.


Eventually the lags would pass and then there would be substantial periods of normality.


FYI I don't use the Logic eq at all, let alone with the analyser running.


I do use things like Fabfilter Pro-Q which has an analyser.


Just felt some duty to report my experience in the hope that it may be of interest to others.


cheers

Well i guess i am in the same box as many others.. It got better but Airplay Questions still comes up its not as often and the lag is better but i need to run on low resolution and try not to have more then 2 Graf plugs at the same time. 10.8.2 & 9.1.8.. This ***** big time because it just feels like they minimizing all the issues insted of going deep and try to fix it from the ground up. I know Logic has a old "motor" but man others are running miles ahead now. Soon it will not be so much of a hard question to leave for others. Just look at Ableton 9 that is coming next year..


Worried and starting to get gray hairs of all this... :/

Yah...

Same here. Some improvement, but definitely not nearly as good as running Logic with snow Leopard.

Attempting to modify setting on a single open EQ at default resolution during playback resulted in a delay in the graphic updating and no response when attempting to stop playback.. probably a 5 second delay or so..

I'll throw in as a civic duty.


Was on LP8 until a couple months ago (bought 9 in anticipation of having to have it for future upgrades). O both 9.1.7 and 9.1.8 the play head and transport both stop when commanded via spacebar, but the audio engine continues for a couple beats after 'stopping'. I have to believe this small issue is related to the UI 'lagginess' that has been covered in great detail here and elsewhere. One empty audio track or 24 VI instances+audio loaded; no difference.


Also, meta commands - specifically 51 and 52 'stop playback' and 'go to marker' in tandem are basically useless. Logic stops a beat and a half before the meta region, and since the play head stops there it doesn't 'go to marker'. 'Go to maker' alone in a meta region 'works' but there is a 'hiccup' in playback of a beat or so probably because the play head jumps prior to the MIDI region w/the meta data.


Of course none of these issues existed in LP8, and they still don't when opening projects on LP8 in my system.


Hope they work this out soon.
