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

Hopefully this has finally been fixed, then! Tonight I'll try running Logic through its paces on a project which was causing the problem very easily.

Seems to work for me as well. Lion 10.7.5 here. Wish i would have known this was coming out a few days ago, i spent a fair chunk of a day putting a Snow Leopard partition on my Imac for the sole reason of eliminating Logic's GUI lag haha.

Seems to be sorted here, though I fear may be jixing myself, so will report back after a weekend of heavy usage!

Regardless, I can't help but be excited! 😉

This lag issue wasn't introduced with a new version of Logic, but with a new version of OS X. The fix (for problems people had with Logic's plugins) came with a new Logic version - not the problem.

If the problem still appears for people using certain other plugins, I guess it's up tp the 3rd part developers to release new versions of their plugins.

Lol , same problem with 9.1.8 , as ppl said before - Just slightly better ! Just installed clean ML on External drive , clean logic 9.1.8 , latest plugin alliance and Waves Suits. Lagging , freezing, annoying ) **** u Logic guys , are u joking ?

But in SL Logic acts perfect and smoother then it was , and thats great )))

If you're seeing it with third party plugins, they may have to fix it on their end.

Logic 9.1.8 seems like it fixed the slow downs on my system. Mac Pro 1,1. Lion 10.7.5 (the highest my Mac can be upgrade to), upgraded with the ATI HD 5770. Just ran a song in a loop for 30 minutes, Channel EQ up with the analyzer turned on, and two 64 bit third party plug-ins that used to immediately cause the issue (Vengeance Metrum, and Brainworx/Plug-In alliance BX Digital). On my end third party plugs seem like they're benefitting from the update too. There's still a SLIGHT delay when clicking to move to earlier or later bar ...but after that it's back to be being totally responsive.

ok, i just checked the issue on my installation with the latest update. the freeze is gone on my side. but, if i look closely, if i open the normal meter (normal + rms) and then open the adlimiter and then the multipressor, the refresh rate of all meters reduces dramatically and the metering gets extremely sluggish. If i close all windows except the one meter, the reaction goes back to normal. it seems, they are making a workarround reducing the speed of the display update for the animations. so the freeze is gone but the feeling to work with the meters is also lost a bit, at least for me.

can someone confirm this observation?

Update, checked on a second computer. its enough to open the meter and the multipressor to reduce the graphic update resolution of the meters.

If I have 3 eq's in hi-res running at the same time, I get sluggish metering too. Although I don't get the freeze/lag issue, I can live with a bit of sluggish metering.

Oct 25, 2012 2:14 PM in response to SimonB76

I agree, better than not being able to work at all. i just had an odd feeling in the moment i switched on the second and third plugin. i will see the next days if I can live with it in my normal workflow.

I think that's kind of what you might expect, though - the AdLimiter is particularly processor intensive - anyway, meters can only give you a general guideline really, whichever type they are - the old Vu meters on analogue stuff weren't exactly precise - if you look at the wave form of an audio sample, you wouldn't want it to the be that precise, would you - it'd just be going all over the place, so you do want some kind of balancing out process, it does become down to what it means in your experience.

It's not a barely-noticeable slowdown though. The analyzer on the channel EQ is basically useless when it happens. It is completely worthless when this happens. But at least it fixed the GUI lag and you can work around it at least.
