why is playhead out of sync with audio ? logic X 10.1

LPX 10.1 Playhead is ahead of actual audio, it is slight but enough to throw me off when looking at transient I want to edit, while playing back.


It does not play ahead in LP 9.

Late 2013 Mac Pro (trash can). Yosemite 10.10


when I set audio setting to internal it is still ahead coming out of trash can speaker so it is not interface.

Mac Pro (Late 2013), Mac OS X (10.7.5)

I know what you mean..


I find myself having to really focus when I'm working in LP9 these days or answering questions regarding LPX because it's so easy to forget which version I'm talking about or using....


I've got to decide over the next couple of months if I want to switch over to LPX full time or not.... simply because trying to use both, is just so confusing... and each has benefits and negatives.


Got to say that 10.1 with it's VCA style faders and region based automation, for my work flow, really is a big draw... That and the fact I have been offered one of the new Mac Pros in a crazily good deal.. that I cannot realistically turn down... but that means using LPX so that will force my hand, if I decide to go down that route...


Argh!!!!!

Art, if you went for the Mac Pro would you run 10.9.5 or 10.10.x? I don't even want to touch 10.10.x at the moment, a test install on my 8 core 2008 Mac Pro being bad enough.


Have quite a few people asking me about new systems and I'm sticking to my Mac mini 2012 (if they can find one) and 10.9.5 OS advice. One guy runs 2 big monitors and has a PCI motu sound card. Trying to find a PCI caddy with a thunderbolt through so they can still use their 2 monitors. It's becoming a backwards nightmare.

From what I have been told I have to run 10.10.x in order for complete hardware support to be available for the latest Mac Pros... so there isn't a choice.

Oh yes..... I understand that completely!

Thx,, it was a electronic template I was running that has, bunch of channels with plug ins, and limiter, and multimeter on master,

i have to turn PDC off to see accurate scroll of play head.


But the exact template in LP9 does not do this at all.

I bought X over a year ago and never use it because the software is so clunky and slow I open up the same project in LP nine and everything runs smooth.

I downloaded the update and gave it another chance but it's just graphically slow.

Apple is a hardware company, got to keep the hardware moving.


I used to kid about this but I'm beginning to think that Apple's constant upgrading of OS and hardware is to help shore up the bottom line, in other words, a calculated move. Especially when new software performs poorly or is unstable on machines only a couple of years old (in some instances).

If you are finding poor performance with LPX in Yosemite....


This 'trick' seems to fix it...


1) Open a terminal

2) Enter and run the following command, entering your password when prompted:

sudo nvram boot-args="debug=0x10"

3) Restart the computer

if that doesn't help then do the following instead...

1) Open a terminal

2) Enter and run the following command, entering your password when prompted:

sudo nvram boot-args="debug=0xd4e"

3) Restart the computer

I've been testing this (the first one) all day and so far it has worked very well indeed... but as always, such 'tricks' are used at your own risk...
