In other words, if the charge across each capacitors plates is the same, as Q is constant, then as its capacitance decreases the voltage drop across the capacitors plates increases, because the charge is large with respect to the capacitance.

Then the two voltage drops of 8.16 volts and 3.84 volts above in our simple example will remain the same even if the supply frequency is increased from 100Hz to 100kHz.Īlthough the voltage drops across each capacitor will be different for different values of capacitance, the coulomb charge across the plates will be equal because the same amount of current flow exists throughout a series circuit as all the capacitors are being supplied with the same number or quantity of electrons. It doesn't help to change the output of these different aux channels to different stereo outs, neither deleting all plug ins on the main stereo out will allow distribution of the processing to be done to different cores.Note that the ratios of the voltage drops across the two capacitors connected in series will always remain the same regardless of the supply frequency as their reactance, X C will remain proportionally the same. With regards to aux channels, it's not enough to bypass, turn them off or muting them - however enough to terminate all sends going to them. This meaning that only by deleting these aux channels or plug ins on them and the main stereo out, I release the strain on the one overloaded thread/core. It seems like logic can't distribute this combined workload to separate cores! I think I can also add now, that it seems the channel strips that are working as aux channels for FX sends (reverb, delay etc) are the ones causing the trouble i combination with the plug ins on the main stereo out! I've tried starting stopping 5-6 times in quick succession - letting it roll about a second. It seems everybody has these problems, but that doesn't make mine less frustrating.

(I also have to Pro tools TDM HD cards in the machine, but they are not used with logic) I also have a UAD Quad installed via PCIe Graphics ATI radeon 1GB - it runs a 27" apple cinema 1.5 GB SSD (i also have internal 4GB spinning disks inside)

I normally have set processing threads to auto (16, as I am on a mac pro 4.1 with 8 cores), but I have tried all other settings even down to 2, which doesn't affect playback issues as it's still only one thread that is tripping.Ĭhanging the rest of the configuration options doesn't have any effect on the issue! I don't have playback live engaged, and I'm currently mixing, so it has nothing to do with armed/input monitoring instrument channelstrips. But generally it's the overload of one thread, that is the issue.
Sessions that sem to have more going on, can playback better. Yes, it's very different from session to session, how bad the problem is. But I also have plug ins I can activate and force error messages and complete inability to playback project. Yes, I have problems when scrolling with mouse etc.
I cannot seem to force logic to distribute tasks between threads. I have tried following this advice: Logic Pro/Express: Tips for balancing multi-core performance - Apple Support. And please notice the overall strain on the CPU is peanuts (89% idle CPU): Here is a picture, where it's clear to see that setting logic to half the processing threads (8) does not help. So now what is causing the strain on the CPU seems to be a 5 sends, especially one running a reverb with tape emulation and eq'ing. In the session on the pic, I have even tracked most of the action. I believe it may have started around LPX 10.2.x, possible earlier.
