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

we are all fully supportive of possible solutions but that cause is sadly irrelevant because more than half the people on this thread I'd guarantee do not use or even have a magic trackpad.


Its been documented and admitted BY Apple to be a major problem in the coding as the way graphics are handled in Lion/Mountain Lion compared to previous OSX versions has been changed.


Needless to say, Logic, with its ANCIENT code, is one of the major victims of this.


We have to wait until 10.8.3 and even then Im hardly optimistic.... Have you read how many betas of that have been sent to the developers? an INSANE amount. I worry.

I know we're obviously not allowed to discuss the ins and outs about beta's but 10.8.3 might come with some updated drivers for newly supported hardware (doesn't take a genius to work that one out). And if that's the case then the introduction of 10.8.3 may possibly introduce a replacement/update for the aging MacPro. Surely the EU ban of sales of the Mac Pro because Apple not adding fan guards for just a few pence/cents and the delay in 10.8.3 is surely all relative?


Apple could have released a second supplement 10.8.2 update to address the key issues we're all experiencing, surely that would have been more beneficial to the Pro users.


Anyway, I'll get on with this remix running sweetly on my Snow Leopard..

Yes I assumed that what I posted did not apply to most of the posters on this thread.


I simply posted it to correct my earlier assumptions about the performance of Studio One as they were not completely a result of the same issue you are all experiencing. As I posted I am still having an issue with gui lag, but it is slightly diminished when using a normal mouse.


I also posted it for the few people that happened to stumble on this thread with the same issues as I. Considering this is one of the few search results that came up for me, maybe somebody else will stumble on that and it will help 🙂


Good Luck guys!

Didn't change a derned thing for me, unfortunately. Not more than 15 minutes into a session working on a track with only 32 tracks (all but 3 of which are audio recordings) I experienced the lag just as badly as before. It occurred, as in the past, when I opened Channel EQ and engaged Analyzer. I didn't have any other plugins open. All I'm using in the way of plugins and instruments are some Waves compressors, Valhalla reverb, Kontakt, and all the rest are Logic's own native plugins.


Gaaaaa... what now?

😼 Unbelievable. How can a company with the size and "talent" of Apple take this long to release a patch and it still doesn't work???? I'm incredulous. Still, thanks for the heads up, I won't waste any time updating my ML partition. Of course since I updated Aperture I now have to reboot evertime I use it as it won't work under Snow Leopard anymore... Well done Apple, every day you're innovating, finding new ways to make what I do take longer. It's certainly "thinking outside the box", I'll give you that; not sure I like it though...😠

Pancenter, I'm not sure how such a sporadic Logic bug can be considered fixed after half a day of usage, but just fyi, a friend of mine on the SCOREcast: London group has announced from England that the update officially did not fix his issues either. So it's not just me.


I'm not suggesting people shouldn't do the update. Do it, of course. But just saying, it didn't fix my lag issue, as I'd really expected it to.

Fredo,


Remember that some people have been using the beta versions of 10.8.3 prior to it's public release... so for some, it's not just a case of a 'half a day of testing'...... but have actually been using this fix for about 10 days (which is when the beta that included this fix, was released I believe)


The feedback I am getting/seeing is very positive in regards to this particular fix... Much more so than after the last fix... Time will tell just how effective the fix is of course, but so far, so good...

Yes.. Compared to the last supposed fix, the feedback is much more posiitive...


So far I have only come across your continuing issue plus the report you gave of someone else and that's it...


Last time the boards were flooded within a couple of hours with people for whom the fix did not work. That hasn't been the case this time around.. and remember, people only tend to post when something doesn't work, rather than when it does work!


Of course, as i said, time will tell but so far, so good (in comparison to the last time a fix was issued)
