My ears are ringing from blast of white noise from Logic 9

Hi, you are not alone.
Have the same problem but with 8.02 and apogee hardware. I have to wait for Logic9.

In the middle of a recording session, that was a "noise" ! Wow !

I want to know is it a logic problem (8 and 9) or a problem of the apogee ?
Hope the new ensemble driver will help.
Cheers

Yes, I've had blasts of noise too, in testing L9. Nothing triggering it that I can identify or repeat, although once it seemed to happen as I was bypassing a plug-in on playback. Never happened in 8.0.2, and I'm using the same machine, with the same Apogee converters - my LP9 is on a separate bootable drive with 10.6

yeah its defo got something to do with muting and unmuting plug-ins, and also moving plug-ins by hand, on a playing audiotrack, bus or aux or whatever.
its really annoying! it shouldnt be there! logic is better than this.

This has nothing to do with moving or muting plugins. It's happened to me over the years in Logic 8 (only when overdubing and only hearable on playback, not while recording) and now 9 with a clean install (while recording), no third party plugs, and one or more audio tracks in record. I had this happen in a session with logic 9. The band ripped their headphones off, it was that loud. I went back to 8 to complete the session. This is a serious problem.

Yeah it def. has nothing to do w/muting or unmuting...I can confirm this on 3 different macs in Tiger and Leopard running 8.02....its absolutely unacceptable, I thought it blew my monitors one day when I just opened a file and whammo....not cool at all. I got into Logic cuz I thought Apple would have this thing working flawlessly w/Apple computers and it has been every bit the opposite experience for me, very frustrating.

After finally getting my UAD plugins working again (had a serious problem due to my energy saver settings), now I've moved on to the next problem - just started getting the noise blasts today while attempting to adjust settings on the Neve 1073 and the Pultec EQ. Had to save and quite and reopen to get it to even play the song, otherwise just the beachball and then eventually a system overload message over and over.

So for me at least, it seems connected to plugins. Now I'm scared to adjust anything for fear of the deafening white noise. Just updated to Snow Leopard yesterday, don't know if this is related to that. Is there a work around?

Reinitializing core audio may help. You can reinitialize by going to the Audio Preferences window, changing something (like the buffer size) and change it back, so that the Apply button becomes active. Clicking that then reinitializes core audio.
I also think it is due to a (SI) Plug In gone (temporarily) bad. Or an unintentional loop in the signal flow.

regards, Erik.

Thanks Erik. Reinitializing core audio helped until I touched the Neve plugin again and immediately back to static and then no audio at all when I try to playback again. I after much frustration I changed to 1024 I/O buffer and Medium Buffer Range, and that seems to be helping at the moment. My UAD plugins seem to be cursed...

I remember reading this post and hoping it would never happen to me. Alright, it happened this morning. White noise at peak volume. Extremely disturbing. EXTREMELY! Not happy at all… This happened during playback in a recording session with ALL plugins turned off.

I started freezing tracks for the first time ever on regions where I used the Flex Tool. I see some discussions are linking the white noise to freezing.

It took Apogee six months to make a compatible driver for Leopard. I was getting kernel panics every day until then. So now I'm suspicious of the Duet also.

So, how do I turn off Journaling on my audio drive? In System Profiler my music drive says, "File System: Journaled HFS+"

Yes, LP9 is full of bugs. Up until now (for me) they were mostly interface behaviors or there were workarounds that I could find. Deafening white noise is more than a little problem. I'll try re-initializing the core audio too.

I've spent a LOT of time and money on a system that was running perfectly. Why would Apple fix something that wasn't broke, thus breaking it?

OK, it was the freezing. No visual wave form. The noise was from 0 to the start of the first region. Unfreeze and refreeze fixed it. Another bug. I'll be turning my volume WAY down for now on after freezing a track.

Anyway, I went back to work on my little project and within a couple of hours Logic was running SO SLOW it became unbearable. Over 5 seconds to zoom or change screen sets. Frustrating. Now I see a lot of people with the same problems talking about their equipment and wondering if they need to upgrade. I've got the best computer Apple makes. It's maxed out. And Logic just doesn't work any more. It's no longer a professional application. You can't open a recording studio and expect people to stand around waiting for you to get Logic to work. They've taken the Pro out of Logic. Too bad. I feel like I've wasted 3 years learning to use a DAW that is a joke. Maybe I've love it again tomorrow. For today, I've had enough!

Open *Disk Utility*, in the left column, select the right Volume (part of the disk, indented) , hold option, and choose *File>Disable Journaling*.

The Option key...of course! Alright, journaling is disabled. Thanks Erik.

Pancenter, yes, Bee Jay's report from London was a little ominous. I don't mind the marketing guys making Logic look like SuperGarageBand, if it still works. Hopefully the Logic Tour will return to my neighborhood soon. We haven't had any kind of Logic seminar/demonstration in the Miami area for a couple of years now. I always learn something at those.

I got a full on random blast of digital noise yesterday, with headphones on, while recording some drums. Bad bad bad.

The noise burst was actually recorded, but did not show up in any of the waveform displays on screen. So when I played back what I had recorded... I got it a second time, with no warning. Bad bad bad!

I had exactly the same problem - I had to switch my recording session over to Pro Tools to complete it.

We all had ringing ears after Logic's noise bursts as well - not good for professional recording (well not good for anyone really).

Certainly didn't with help my "Logic is as good as or better than Pro Tools" advocacy.
