Major UI Lag in Logic Pro 9.1.7 on OS 10.8?

Hi,


I've just completed my first session in Logic 9.1.7 on a Mac Pro Quad Xeon 2.6 after upgrading to Mountain Lion 10.8. I got through it, but experienced the following new bug (as compared to running in Lion 10.7.4:


I noticed that if Logic is currently playing when I double click on a plugin in the channel strip, and then try to stop the playback (keyboard or by clicking the transport in the arrange window), I will get from a 5-45 second lag before the app responds and actually stops. No mouse or keyboard commands seem to work while it's hanging up.


Workaround: Only open plugin windows when playback is stopped, and then playing and stopping works fine (although maybe a little more laggy than in the former OS still).


Is anyone else experiencing this or have any better workaround ideas?

Mac Pro, Mac OS X (10.7), Quad 2.66GHz, 16GB, 18TB HD / RAID

Seems like all those plugins are having issues with Logic still and Mr Duda may have updated something in the code for LFO Tool.


Indeed... From what I have seen... Apple have contacted developers via the Development forums and have informed them of the changes they need to make to their code to ensure a minimal issue with "Gui Lag' in line with the recent chages to OS X and Cocoa's frameworks.. Some Devs have already implemented these changes (if needed in their plugins) and other's haven't.. hence the continuing issues with certain graphically intensive plugins.


is there any real reason for you to believe that Apple is involved in this issue?


See above... plus look at the release notes from recent OS X updates and you will see that the problem actually lies within OS X itself due to changes the OS X Dev team made to certain routines and Cocoa's frameworks..as far back as Lion..and not Logic per se..

I'm running 10.8.4 and Logic Pro 9.1.8.

The other day I imported a single .aiff file from a low-level recorded movie just to tweak it. I often use Multipressor and Ad-limiter in the output channel. Now with just only these two plugins, and onlly one lone audio track, Ad-limiter no longer runs smoothly. I hope this would not be considered off-topic...

For me it's not really life-threatening in a general sense, as I no longer work on large multi-track projects, and so on. But things don't seem to working as they should. Audio interface is old Motu 828, and midi mixer "Logic control". Good luck all.

I am praying that mavericks has done something about this Lag issue and that it will be solved. Cause the utter hopelessness and loss of finances that this probelm has caused me is devastating. I even tried apple support but aparently you cant be called by them if you are in South Africa and I have no idea how to call them from my location and neither do they.
