Big problems with Logic 9.1

[manymax]

Hello I decided to write this message because I have very big problem with Logic 9.1 .The problem is that I just updated with the new version of Logic 9.1 and since then I have very high latency issues.The problem is that all tracks sound with a latency, this always happens in the final stage of a mix when I'm starting to create the automations,before this all sounds good and without latency.A part of this problem many times I have problems with white noise issues,the noise that comes out is so strong that I'm afraid of ruining my studio monitors.Before upgrading to the Logic 9.1, I never had these problems with the Logic 9.02 version.Wanted to know if this is happening to someone else to.I was thinking of buying the Leopard Snow with the hope that these problems are due to that the new update of Logic 9.1 is designed for Leopard Snow and I have Leopard 10.5.7 instaled on my computer.The truth is that I have no idea how to solve these problems and I have customer who is waiting to finish whit the mix of some tracks.
P.S
I have a Mac Pro Quad Core 2x2.8Ghz - 10GB Ram computer so I don´t think this are problems with the system requirements for Logic

Haven't noticed any latency differences from 9.02 to 9.1 here. You said it's happening in the mixing stage. What plug-ins do you have on your master fader and also do you have any buses going that have plug-ins on them? How do you have delay compensation set? Most limiters have quite a bit of delay so if your using one on the master that could be where the latency is coming from. Also what buffer setting are you at? As for the white noise that's been happening since logic 8 I rarely see it because I mainly use logic for programming and occasional mixing as I do most audio work in PT but I have experienced it many times on other peoples systems.Sadly I don't know that there is a work around for it. Making sure the drive you're recording to isn't to full may help. Also it could be tied to having the buffers too low as it seems that its caused by a disc access error. Hope this helps.

You are aware of low latency mode right?

9.1 is great for me.

[manymax]

the truth is that I also was thinking it might be the problem in a plugin, but I'm turning off all the plugin that I have on the master track and the problem remains,apart from this I'm always mixing in 1024 sample rate , and the latency compensation on the preferences of Logic is set to compensate all.

[dankin]

I'm assuming you mean your buffers are set at 1024 not the sample rate. At 1024 you're going to have a lot of latency for sure regardless of plug-ins. I usually keep mine set at 256 unless I'm monitoring through logic while tracking then I will set it to 64. The highest I've ever had to set it was 512 and that was with a ton of VI tracks streaming some big samples. With your MacPro you should have no problems running at 512 or 256. What audio interface are you using?

[Lagerfeldt]

I use a buffer size of 64 when recording. I use a buffer size of 128 when producing and a buffer size of 256 when dealing when any kind of critical real time processing involving I/O.

Try clicking to a different setting, like 'off' and then click back to 'all' again. I had this problem once or twice and I found that did the trick; worth trying anyway.

erm... the 1024 is not a samplerate but a buffersetting. If I'm not mistaking the highest. That what gives you lots of latency. Add to that the compenstation setting set to all and you create a huge latency, unworkable if you ask me.

As for plugins on the master; if you happen to have an adlimiter on there, be aware that to bypass its latency you must take it OUT of the master, not just deactivate it. It's one of the few logic plugins that gives latency even while deactivated.

EDIT: Sorry I hadn't seen Dankin already explained the buffersetting. Mine is on 256 always too.

[markham]

Yeah, definitely no problems with 9.1 here. I'm liking it a lot. I'm running 128 or 256 all the time with no stability problems at all. And I also have never had the "white noise" problem that some folks have reported in the past.

Of course, in the meantime, to finish up for your client, you could always use 9.0.2. The 9.1 install didn't overwrite 9.0.2.

[manymax]

sorry was my mistake, I meant buffer size 1024.The truth is that 1024 for mixing is the best option for me and to record is better 128 or 256.But the problem is not this, because I always used 1024 buffer size for mix and I NEVER had problems,and this considering that before and had computers with the half of the power that has my current computer.The problem is since I installed the new update from Logic 9.1 on my computer, I never had problems with latency before.The sound card I'm using is a RME FireFace 400

Is it a session started in a previous version? Did a couple sessions with no problems when starting from scratch in 9, but I'm having odd issues with a session from 8. Unfortunately, in my experience, it's not unusual to have issues with sessions started in previous versions with Logic. You can always either start fresh our try starting a new session and importing the tracks.

Thanks for that

all projects are on Logic 9

This is a widely-reported (and unforgivable) issue with recent versions of Logic that you can read a very detailed multi-page thread about on the Apple Logic Discussion Forum.

As far as I know it has still not been resolved despite various incremental Mac OS and Logic updates.

[dankin]

At a vocal session last week at a friends place here in Nashville I witnessed the white noise blast about 4 times in less than an hour. Fortunately it showed up in the waveform as a solid block every time so we noticed it before every ones ears were blasted but I know that sometimes the waveform renders normal and you still get the white noise blast. My friend said he gets it several times a day. This is a SERIOUS issue. A person could suffer severe hearing damage from this aside from the chance of blown tweeters and headphones.

Supposedly the upcoming Snow Leopard 10.6.3 update addresses some issues specific to Logic 9.1.

Upgrading to Snow Leopard is a good idea..

While you're still using Leopard - it probably would be advisable to upgrade to 10.5.8.

Sorry if this sounds harsh, but when you're in the middle of a project's especially a client's, you don't make updates... In other words, don't fix what's not broken! Wait till you have sufficient time and resources on your hands to properly put your system up to date. So that way, if something goes wrong, you don't have to deal with it as if your life depends on it! Call me a freak, but I also make an integral backup of my OS HD before any update (system OR software)... That way, I can revert easily and rather fast if the update happens to go berserk on me!

This is always something you get to learn the hard way! Sorry!

[markham]

also, is there any chance you're running 9.1 in 64-bit mode, or are you sure you're in 32-bit mode?

the truth is that was a mistake to update my system, but I was thinking that this update can solve many problems, or at least it said this in the Apple Update page.The next time I will think twice before update something

I am running logic9.1 in 64 bit on an Imac i7 quad 2.8hz 10.6.2 .The same song opened in 32 bit mode flies and the playhead is immediate as you would expect but in when I open it in 64 bit it is really sluggish and takes a 1/4 sec to react when I press play.

Any ideas?

[markham]

What kind of plugins are you running? All stock Logic plugs, or some 3rd-party plugs? If 3rd party, are you sure they're all ready for 64-bit, or are you having to run the 32-bit bridge?

What audio interface are you using? Are you sure you're using the latest driver, and is it capable of 64-bit operation?

Sorry if those are really basic questions--you've probably thought of those already. Just trying to think of anything I can.

But in this case, it's not not broken..

[molemac]

I have latest drivers for rme fireface. BUt I am using 3rd party with the 32 bridge so I guess that must be the issue . Lets hope 10.6.3 fixes it.
