Logic 10.2 weirdness

[elser]

Jon. Email me a link to your template session so I can try it out here.

Key commands: you will have to choose one of the preset layouts.

General prefs: no reason why by default you would see the control view instead of the gui. Weird. Also the latency. Btw - since my template is fairly loaded, I always run at 1024 samples - also due to using the UAD pci quad card.
To record I have the "low latency mode" assigned to a key command, and I enable that any time i record. Then toggle it off to mix etc.

Is your template newly created on logic X? Or is it a logic 9 template that you carried along?

Also logic 10.2.1 just came out two days ago.

Hey Andy, So on the key commands is there a preset layout that will assign the tool kit back to the numbers? That is really annoying as I use that stuff all the time.

Lately I've been using the stock blank template because I've just been doing a lot of sound design stuff so I don't need a lot of instruments loaded.

"Low latency mode"? I'm not aware of a key command, I've always just switched back and forth between a 1024 and 64 sample buffer.

And I upgraded to 10.2.1 and still have the same issues.

One other strange issue, I usually press the space bar to begin playback, and there's always been quite a lot latency in the start of playback. This has been an issue since I first got the computer.

I think you violated a cardinal rule, never do any updates until after you finish and submit time-critical projects.

You should be able to change the key commands.

Yeah I know... but the whole system is new to me so I'm trying to get caught up.

Hard to guess what's wrong re: latency, but I would use Andy's method of a larger buffer, and then switching to low latency mode for recording. Easier and quicker than switching buffer settings. Also, 64 is pretty darned low

There's also a new multithreading feature which improves performance. You want to make sure you have turned on. Preferences=>Audio=>Multithreading; select 'playback and live tracks' and just leave it there. You have probably poked around other audio prefs already but make sure nothing there got changed 'by itself'. You might even trash your logic prefs and start over (never seen the GUI issues you mention).

I've been running 10.2.1 for a few days, and it actually runs better for me. What OS are you running?

I'm not even getting the GUI, I get the controls view which is just a lot sliders and knobs. Of course I can manually switch to the GUI view but it's strange that by default it comes up in controls view. What's stranger is that say for instance I want to select the velocity tool ,it's no longer assigned to number 9 but it's assigned to a letter. It's really slowing me down.

Ok - preferences > display > mixer >

make sure the "open in controls view" tick box is NOT checked.

close and reopen any plugin windows to check.

Thanks Len, yea I agree it's a preferences settings thing. I just don't know which ones to change and why they changed in the first place. And then there's the latency thing. I literally can't play guitar in real time, there's so much latency. It's a new computer to me, a 2009 Mac Pro modified to a 12 core Westmere, I'm wondering if there's something in that aspect that is the problem.

from everything I know Jon - the firmware update and the 5,1 processor trays turn that 4,1 into literally a 5,1.

there isn't anything left that is 4,1.

So charitably I would say the answer is not in the machine (with the caveats that we spoke about via mssg before - as long as the upgrade was done correctly - which you can verify in "about this mac") then you can be assured its not the machine.

Well I figured out key commands thing. Apple changed them in a recent update, so the key commands I've been using for years are suddenly changed. On a day when I have to get 3 projects in on a time crunch. I love apple products but sometimes they can piss you off.

this happened for me going from logic 8 to 9, and logic 9 to X. Things were slightly different.

btw - in key commands preferences (from the file menu) i have always chosen U.S.

I have had to add a couple of my custom ones back in after these updates.

noted above

no problem. I usually use a template because it has my usual suspects for reverbs and such as well. YMMV.

"Low latency mode"? I'm not aware of a key command, I've always just switched back and forth between a 1024 and 64 sample buffer.

yes you are actually reducing the latency by making the processing buffer switch between 1024 and 64 samples (which is low, but its the only choice for me if I ever mess with it - otherwise I play out of time with the recording).

the actual command is "toggle low latency mode" (which you can set a key command for in the key commands edit window) and its a button that is available by customizing the transport bar - it looks like a sports car speedometer and is orange when activated. there is also a setting that helps fine tune how much latency there is even in "low latency mode" in the preferences > audio > general tab under "plugin latency"

so with a 1024 sample buffer the latency is 49.5 ms roundtrip (24.3 ms output) - and activating low latency mode trims that to 5 ms. Or whatever you set the slider for in Preferences > audio > general. 5 ms seems to be fairly unnoticeable. Using the key command this happens in a blink.

When using the UAD plugins I usually do, it takes a minute to recalculate, and reload all the Play / VSL / Kontakt plugins I have in my session. So switching buffer sizes as you do is something I never do unless I need to go make coffee.

I usually press the space bar to begin playback, and there's always been quite a lot latency in the start of playback. This has been an issue since I first got the computer.

This is likely related to how your hard drive scheme is laid out Jon. I have had this issue a number of times in the past, but usually when 1) scoring to picture and 2) using Logic 8, and 3) when my hard drive scheme wasn't nearly as streamlined or as fast as it is now.

you would have to google to see what the issue is and whether other people have experienced it. I remember doing that and not coming up with much help.

like I said, I think it has to do with scoring to picture, and trying to stream too much off too few hard drives. Like running OS, Logic, streaming video off the same drive isn't ideal. Nor would doing any of those things and streaming samples off the same drive. Etc.

agree with this.

here is the standard things I do if Logic starts doing really funny things (which happened ad nauseum with my old Digi 002R cause the drivers were shite but hasn't happened since I switched to the Apogee Duet 2).

1) trash pref files. Preference files are always rebuilt from default when you delete them. That means you might have to re-do some things like key commands etc, but at least you can start clean from scratch

user....... > library > preferences >

com.apple.logic.pro.LSSharedFileList.plist
com.apple.logic.pro.plist
com.apple.logic10.LSSharedFileList.plist
com.apple.logic10.plist

etc. Google to find where your pref files for logic are on your machine in your OS if you don't see these.

2) empty trash, reboot etc.

3) start a new empty project.

etc.

Also: Since the update I can set my multithreading prefs in the audio engine from fixed "12" back to "auto" (I´m using a modded Mac Pro 2009 Westmere 2x 3,33)
On older Versions including Logic Pro 8 and 9 there was a lag when stopping Logic: it was still playing on for at least half a bar, this issue is done now!

One of the new features in 10.2.1 is a setting that lets you allocate some of your Mac's multicore CPU power to your live instruments when recording. It seems that when that is turned on it takes some of the Mac's CPU power and allocates it for live instruments even if you aren't using any live instruments.
There is a setting under Preferences/Audio where you can have Multithreading available for just Playback tracks or Playback tracks and Live tracks. The default is for both. When I changed it to just Playback Tracks my session ran as before without any overloads.

The Mac Pro (Early 2009), Mac Pro (Mid 2010), and Mac Pro (Mid 2012) computers implement PCI Express revision 2.0 for all four slots. Slots 1 and 2 are x16 slots, and slots 3 and 4 are x4 slots.

If your UAD pcie card is in slot 3 or 4, move it to either 1 or 2.
