Q: Sudden latency when recording in Logic Pro X on Mavericks and Yosemite

Hi All,

 

I'm experiencing a sudden increase in the latency of my audio i/o during recording/playback.

 

It occurs after a short while, and has happened during playback, recording, and when my interface has been idle.

 

A crackle, and a glitch in the recording/playback will occur, then suddenly the latency is increased quite dramatically.

 

I'm using a Roland UA-1010 octa-capture with Logic Pro X, on a MacBook Pro (Retina, 15-inch, Mid 2014), with Yosemite version 10.10.3 (14D136).

 

Had the same issue on my old mid 2010 macbook pro as well. Never had this issue before upgrading to Mavericks, and it didn't go away when I upgraded to Yosemite. And it still happens on my new MacBook Pro...

 

If I restart the interface, the latency returns to normal, until the fault occurs again.

 

I've tried increasing buffer sizes, creating aggregate devices, changing the clock master, sample rates etc, etc, none of this helps...

 

I found a similar thread in the Mainstage area, but I'm experiencing the same problem when using Logic, and after reading through everyone's posts, I'm pretty certain it's not a DAW or specific audio interface issue. Though other people have had the same issue with the same and other Roland interfaces... This is the thread:

 

Suddenly high latency

 

Does anyone know of a solution to this issue?

 

Has Apple commented at all on this issue? It seems many people are experiencing it.

 

It's extremely frustrating as I record professionally and this is hindering my work. It's making me look bad...

MacBook Pro (Retina, 15-inch, Mid 2014), OS X Yosemite (10.10.3)

    Yours is the main reason I avoid USB Audio interfaces at all costs.

    The Roland looks like a nice unit, are you using the latest drivers found here.

     

    http://www.roland.com/products/octa-capture/downloads/

     

    Also, does the Roland use an external power supply, it's not bus powered is it?

     

    The main problem with USB is it's under control of the OS, Mavericks and Yosemite are somewhat (cough) heavy handed operating systems, what it comes down to is the OS and the USB interface/drivers butting heads or possible interferences from a background process.  Any other USB peripherals being used?

     

    The secondary problem with USB audio... even if the interface uses proprietary drives they still have to go through the OSX USB subsystem and that is subject to change with every OS update. For instance, support for USB 3.0 in Mavericks/Yosemite broke a lot of older USB devices.

     

    Try creating a New User and see if the problem persists.

    The second possibility... Logic's and presumably Mainstage are having graphics incompatibility problems. Both Mavericks and Yosemite place higher demands on the GPU and Logic's graphics subsystems are not 100% optimized for either OS. It could be the graphics drag causes Logic's audio engine to briefly lose connection to Core Audio.

     

    Next time this happens, go into Logic's Preferences/Audio un uncheck/recheck Core Audio and see if you return to Low Latency.

    Thanks for responding so quickly.

     

    The drivers are up to date, I reinstalled them a few times but to no avail..

    Yeah, the interface has it's own PSU, not bus powered.

    No other USB peripherals are being used.

     

    I've already experienced USB3 issues, I have an ilok2 which stopped working, and I found out it now has to be plugged in via a USB2 hub to work... I actually tried the same thing with the interface to see if that helped, but it didn't in this case.

     

    Interesting that it could be graphics related.. I'll try resetting the Core Audio in Logic's preferences the next time it happens. I imagine it will return to low latency, as I suppose turning the interface off and on again has the same effect, and when I do that, it returns to normal. Any way to remedy this if it is graphics related?

     

    I'll create a new user too, what's the thinking behind this just out of interest?

     

    Thanks again.

    Quite a few have complained about the graphics issue, especially those on "Retina" based machines. Not owning a retina system (older MacPro with 3rd party monitor) I would ask if it's possible to run Logic in non-Retina mode?

     

    The Logic behind running as a new user is not running 3rd party additions that can be installed with other software installations, not quite as good as a clean install but almost. After creating a new user login, I'd reboot and sign in as the new user and see how Logic does.

     

    btw, I missed the retina reference on my first posts, I'm betting your problems are retina based.

     

    Like I said, Logic's graphics are lagging behind, retina makes the matter much worse.

    I've created a new user and have turned on 'run in low resolution' mode for Logic, I'll see how it goes.

     

    The GUI in finder and other apps was running a little sluggish and jittery too, so I reset the PRAM to see if it helps...

     

    Retina may be exacerbating the issue if it's graphics related, but maybe not causing it entirely. I had the same issue with my older, 13" mid 2010 MBP when I upgraded that to mavericks, before I switched up to a 15" retina MBP.

     

    Something else that might help... I was using an Apogee Duet USB interface the other day, which happens to be class compliant, and so requires no drivers of its own. This ran smoothly and perfectly, without any glitches, for about 5 hours during a session, and was on the whole time with Logic running.

     

    Maybe that changes things?

     

    I may eventually end up doing a complete clean reinstall to see if it fixes it, but I'd very much like to avoid that...

    Don't know if it changes things but it does point to the Roland driver as not being 100% there.

     

    Please let us know how it goes.
