BadOrange Posted January 20, 2011 Share Posted January 20, 2011 The core overload issue is really killing me. ANyone know if this is something they are addressing or will they unveil logic 10 first. Quote Link to comment Share on other sites More sharing options...

Holger Lagerfeldt Posted January 20, 2011 Share Posted January 20, 2011 The core overload issue is really killing me. ANyone know if this is something they are addressing or will they unveil logic 10 first. No Core Audio overload issues here. Ever. Try closing all other applications than Logic Pro. Turn off file sharing and Wi-Fi. Make sure you have a least 8 Gb of RAM. Disable hyperthreading and only use real cores (set this in Logic Pro audio preferences). Use a buffer size of 256. Disable 3rd party plug-ins until you find a possible culprit. Use 32 bit mode. Quote Link to comment Share on other sites More sharing options...
SONiC Posted January 21, 2011 Share Posted January 21, 2011 Disable hyperthreading and only use real cores (set this in Logic Pro audio preferences). Are you talking about "Processing Threads" under Prefs -> Audio ? If so, what setting are you recommending? Make sure you have a least 8 Gb of RAM. Use 32 bit mode. I understand these are unrelated if you are troubleshooting. However, is there any advantage to having more than 6GB if Logic is in 32 bit mode and can only access about 3GB? Still a little confused on this issue. Quote Link to comment Share on other sites More sharing options...
triplets Posted January 21, 2011 Share Posted January 21, 2011 The EXS24 and certain 3rd party plugins have their own memory manager that can use more than 3 gigs when you're in 32-bit mode. Quote Link to comment Share on other sites More sharing options...
Holger Lagerfeldt Posted January 21, 2011 Share Posted January 21, 2011 Are you talking about "Processing Threads" under Prefs -> Audio ? If so, what setting are you recommending? Set the number of threads to reflect the number of cores you have in your Mac. However, is there any advantage to having more than 6GB if Logic is in 32 bit mode and can only access about 3GB? Still a little confused on this issue. In my practical experience, 8 Gb of RAM is the magic number when it comes to letting the system and Logic work and breathe, even in 32 bit mode.

In my experience 6 GB is fine but it's nowadays just as easy to buy 8 GB. Quote Link to comment Share on other sites More sharing options...

Lagerfeldt, I recall that you had the freezing/beachball at playback problem, which seems to be processor related since it goes away if you turn threads off..? Did you resolve that problem, and how, cause I have it on my 6 core and it is driving me NUTS and I don´t want to use only 2 threads. best Claesbjo Quote Link to comment Share on other sites More sharing options...
Holger Lagerfeldt Posted January 22, 2011 Share Posted January 22, 2011 I had the pausing problem before playback yes. No beachball or permanent freezin, just the occasional but annoying 1-2 second pause. It's gone now. Updated from Leopard to Snow Leopard and Logic 9.1.3, as well as changing the number of processing threads. Not a single problem since. I can't say for sure if it was the updating or processing thread change that did the magic, but the hyperhreading was the reason for the rare glitch in the system when using I/O (I've tested this, took me a whole day to prove).

Wow, I've just tried this and a huge difference when previewing samples or playback on large projects. Thanks! Quote Link to comment Share on other sites More sharing options...
claesbjo Posted January 22, 2011 Share Posted January 22, 2011 Ok great... How many threads can you use without getting the freeze? My maximum is unfortunatly only 2.. I have the have the 6 core and everything is updated and dandy. Claesbjo Quote Link to comment Share on other sites More sharing options...
Holger Lagerfeldt Posted January 22, 2011 Share Posted January 22, 2011 4 on my Quad Core, if i remember correctly. So once you go above 2 threads it'll start with the problem? Quote Link to comment Share on other sites More sharing options...

In general, there seem to be most problems with the I7 and Hexa based computers. My old mbp (c2d) never has this problem. This thread sums it up pretty much.. http://discussions.apple.com/thread.jspa?threadID=2439334&start=0&tstart=135 cheers Claesbjo Quote Link to comment Share on other sites More sharing options...
druu Posted January 23, 2011 Share Posted January 23, 2011 I would try to delete the logic .plist (from User\library\preferences\) and try again. Quote Link to comment Share on other sites More sharing options...
BadOrange Posted January 23, 2011 Author Share Posted January 23, 2011 It definitely is a bug. The issue is that any instruments with multiple aux channels will only be processed by 1core So let's say contact with 8 outs any insert on any aux is limited to one core.so you get core spikes despite having lots of processing power. It is not a ram or interface issue but rather a poor implementation of sharing things over many cores. Quote Link to comment Share on other sites More sharing options...
claesbjo Posted January 23, 2011 Share Posted January 23, 2011 I would try to delete the logic .plist (from User\library\preferences\) and try again. done that. no change...I think all 6-core have the occasional freeze at playback, haven´t heard of any Hexa owner NOT having this problem..so I am eagerly awaiting an update that makes logic work 100% with the 6 core. cheers Claesbjo[/u] Quote Link to comment Share on other sites More sharing options...
