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

Yeah, and of course lots of us are having the problems while ONLY using Apple's own built-in plugins! For me it's ChanEQ, which is not only a standard built-in part of Logic, it's part of EVERY standard channel strip setting! Am I supposed to just not equalize my tracks or something? That might be good enough for GarageBand users, but not for anyone who wants things to sound good!

Thanks fluffy. +1 i totally agree.

Smokensound i"ve emailed your video to my contact at Apple support, things MUST MOVE NOW.

I never said it was third party's fault, I said have you asked them about it. They may be able to provide some info about what the problem is, and if it is apple's screwup they are in a position to be in touch with Apple and try and get them to fix it.

Do all third party plugs have the problem? I've only seen it with the two logic EQs with analyzers.

With the built in plugs, I see the problem in a huge way on 10.7.4 but it's much improved (maybe totally fixed, hard to tell?) on 10.8.

All 3rd party plugins with graphics activity.

It did worked well with Snow Leopard, so why it doesn't work well with Lion ?

Waves

Vengeance

Xfer

FXPansion

Rob Papen

and so on......

I looking forward Apple's reply.

I already asked some of them, and they're not able to identify reliably the problem...like Apple.

I see some new posts in the forum about Logic slow-down and Mountain Lion, to all people read this! It's the same problem in Lion or Mountain Lion.

Here it's the same. As soon as I use Logic's build in Channel EQ with the analyzer switched on Logic hangs.

Jul 28, 2012 10:06 AM in response to fluffy

I had the same issues when I upgraded to Lion 10.7.x,

extremely laggy UI with Vengeance, Fxpansion, U-He... opening channel eq made Logic crash, slow reacting on faders, like 5-6 secs glitch,

and much much more of those weird behaviours...

Two days ago I did a clean install + mountain lion, it solved all my issues,

it's running very smooth.

Nothing strange to report (Till now at least) 😉

I recommend everyone with those issues upgrading as soon as possible,

or downgrading so SL.

hmm...

ok will try this...but i'm very very sceptic did you really try to challenge Logic ? Here i've upgraded, in two seconds i can make Logic unusable,with just opening a channel EQ.

Jul 28, 2012 12:27 PM in response to hypnotik

Depends on what "challenge" stands for,

this for me is a regular session, which was un-editable on lion 10.7 due to issues, with 16 fx busses:

now it's working nice.

The key here may be "Clean Install".

Mac's are not as simple as they used to be in terms of OS upgrades... upgrading over the top of an existing OS may be asking for trouble with ProApps.

Jul 28, 2012 2:06 PM in response to Pancenter

Loaded a huge session to test few things, lag came back.

here we are 😉

send a bug report to Apple, we all know that Logic doesn't work reliably on 10.7/10.8. I had a bit of hope when i read your message.......but it was just a bit....

Jul 29, 2012 3:27 PM in response to hypnotik

I think I found what's causing the problem got enlightened watching your video on youtube.

uploading a video,

well still got a glitch of lag every 20-30 min sometimes, not totally gone, but I am able to work like this,

it's something graphic related, and 95% it's from logic native plugins.
