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

It sounds like static from corrupted files or misread headers is a different issue than the random bursts of noise. Not that they aren't both serious problems, but probably totally unrelated to each other.

Hi,

ok, sorry, no solution, but at least something to think about: on a thread on www.gearslutz.com about this issue someone suggested that as long as this bug hasn't been solved, it's obviously very wise to put all digital volume controls (the main volume slider in Logic, main volume controls of your audio hardware) as high as possible, so that the levels of the analog stuff that comes after that (like main volume of the monitors) can be as low as possible. As long as you don't overdrive them, it holds noise levels down, and IF the noise burst appears, it will probably be less loud because the you've actually given the monitors less headroom.
I know, it shouldn't be necessary...

If by "main volume" you're talking about Logic's master volume, then no, it's not a good idea at all. Doing so will drive up the level of all Logic outputs. And whereas channel strips can be driven into the red without distortion, outputs cannot.

So.. Has this not been resolved? Im also experiencing all the problems above. As already said previously.. If I even have only a blank midi track in my arrange, the horrific noise occurs between between bar 6 and 8, then disappears. Im a professional producer and to be frank, could not put up with this and have already 'flow the nest' so to speak and have had to invest in ableton Live 8. From being a logic user for over 9 years I did not want to do this. Sod the **** iphones and all the ipad's for a minute.. look after us all like Emagic used to.

Also, I own a pair of £2000+ monitors that I hope haven't been fried / damaged by the noise outburst's and that I haven't suffered any hearing damage (yet to be tested).... I would personally like to know what my rights are against apple.

Hey iSwartz,

Reinstalled my whole computer and at the moment the noise isn't there.. I did this a while ago and it disappeared only to return. If it returns, I will get back on the board and hopefully get a recording of it, yet as said.. I've 'flow the nest' and am really digging Ableton (it seems to have memory issues but at least I don't live in fear of the horrible noise thing).. I do hope apple sort all this mess out as I want to work in Ableton and then mix in logic now.

Regards,
Jon

If you think Ableton can't do this too, think again. On a Dell (and also on a Mac).

The grass is always greener.

21st, from the research myself and others have done on the 'net the problem is not specific to Logic, or specifically version 8 or 9. The link in 45RPM's post is also indicative of this. The blast has been reported on PT rigs as well.

I wouldn't know if it occurs with remotely the same frequency on PC-based DAWs or not because, well, what's a PC? (LOL) but considering Apple has contacted some people to get info on the problem it might be safe to say that it's specific to Macs. Or it might not. Regardless, the problem does occur in conjunction with their hardware while using their software so as far as I'm concerned -- as are the bent cilia in my cochlea from my encounter with this -- the ball is in their court to figure it out.

yes, I know that, but I was told that Logic 9.1.1 includes some kind of protection against situations that provoke this "blast".

Best,

Curious to know -- where did you got this information from?

And if you look back through this thread just one page you'll see a report of this with 9.1.1. Go back two pages and you'll see two additional reports on 9.1.1

is anybody who is still suffering the "blast of white noise" already using Logic 9.1.1, not a older version?

Yes.

For me, I've only had the B.O.W.N since 9.0, all versions, including 9.1.1. 10.5 or 10.6 hasn't made a difference (I thought it was just LP9+10.6 once, but I was wrong). Never with LP8.

I've spent many, many hours trying different combinations of OS and Logic versions, even changing interfaces connected from firewire and PCI . Because it can strike at any time, I can't find any repeatable combination which will induce the noise. It's also infrequent; I could run for weeks with no problem, then get hit twice in the same day.

I don't use Logic for recording at the moment when musicians are around, and so far haven't had the issue. Not that this means much; maybe I could have used Logic without a problem, but I'm choosing not to risk it until a solution is found.

Although it seems that loud noises have occurred on other platforms, the incidents seem rather rare by comparison, and I don't think it's because PT or Live users are shy in reporting problems.

I turned journaling off, use a internal drive, changed interfaces...it STILL happens.

Apple need to respond to this issue with THEIR software, read this thread and also this one http://www.gearslutz.com/board/showthread.php?t=439130&referrerid=91126

Disgraceful!!!!

I'm moving on

Maybe that's a clue.

Could it be related to system updates, maintenance scripts, or something?

So I've had this problem happen intermittently over the months, but yesterday during a very important location recording session, it was happening CONSTANTLY.

I managed to get through the recording but with many interruptions. My pianist sitting at the other end of the room could hear the blasts of noise in my headphones (I was probably 8 metres away!).

Not only was it totally unprofessional, but it came close to ruining my session (and ears). I should send Apple the bill for this: it's simply not fit for purpose.

I would question if there are laws being broken here... but software is such a grey area. As is Apple IMO these days.

Not happy Apple. SORT IT.

Interesting... after my aformentioned expereince in session a couple of weeks ago, I wrote to Apple/Logic feedback and actually got a response... I'm posting here because I think all users will benefit from seeing this:

*Thanks for your recent feedback though we're sorry to hear you're experiencing a problem. Are you using version 9.1.1? The form says you are using 9.0.2 - perhaps that was an error?*

*I assure you we take this issue quite seriously and have spent the better part of the last year investigating it. It has been essentially impossible to reproduce and the nature of it suggest that it is not specifically a Logic issue. We did however take steps in 9.1.1 however to at least block the audio output in the event that conditions arise that suggest it might occur. In that scenario, there would be a loss of audio altogether rather than an audible burst of noise. It will be disappointing if you have in fact experienced this noise burst while using 9.1.1. In any case, we would be very interested in learning as much as we can about your system as it may help us to understand this issue better.*

*I look forward to your reply.*

Well unfortunately I was using 9.0.2 because I need to keep my Macbook cross-compatible with my G5 (when PPC support stopped). But what I thought was interesting is that A/ they have issued a patch in 9.1.1 which blocks audio under these circumstances B/ an admission that it is a problem, but that is essentially impossible to reproduce C/ that they've spent a lot of time trying to fix it without much success so far! The claim that it might not 'specifically be a Logic issue' is interesting, but I'm sure we all agree that our Apple software running on an Apple OS on Apple hardware, is probably an Apple problem.

I did write back detailing more info but I've not heard anything further so I thought I'd post this now. Nice to have some info, but the big question is what will happen from here...

Thanks for sharing this.

we would be very interested in learning as much as we can about your system as it may help us to understand this issue better.

If you reply, would you please include a link to this thread? If they want information there's plenty of it here, including that Excel spreadsheet I made up a while ago detailing at least a dozen people's systems (if not more).
