Duet & firelite drive duet making digital noise

Hi any know of the solution to this problem? I'm working in logic with project files on Smartdisk external firewire drive. I have a 15" Intel Macbook Pro which has one firewire port. I have the duet and external drive daisy chained. I have tracks frozen in Logic as I adjust paning, or send bus all of a sudden I get distorted audio. any advice would be appreciated. I thought at first it might be because I was using firewire hub, but I've taken that out of the chain and still get the distorted audio after making a few adjustments.

Hi widnikprod welcome!
I seem to remember reading about this problem on this forum a while back, don't remember if there were and solutions though.
I guess do the typical first:
Make sure you have the latest software/driver updates from apple and apogee, etc.
But since the hub didn't work, I would look into getting an Express Card 34. This would add a second firewire bus, it would also be handy to have around anyway.

It's so cheap it's worth a try. Connect each to a separate bus and see if it helps. Not sure which macbook pro model you have, but I think even the earliest models had the express card 34 slot.
Good luck!

MacBook Pro Hard drive is making weird noises and slow

its important that you understand what has led to these issues. I first was witing an essay on my MacBook. Whole thing dies, screen freezes and entire thing crashes. i have no choice but to force it off by holding the power button... Then the fun begins. I log in and it gives me a circle with a slash basically telling me no you can't use your computer.. Ok.... Let me just get apple support on chat... after 3 painful hours, they even had no idea what was happening... I erased my hard drive after 4 repairs and verifies.. looked fine sure... Redownload os x 10.10 bam, the issues begin, first you hear a weird high pitched noise that varies from just heard by me to my entire household... Lovely Sure makes doing college work harder in the morning as my roommate can hear it and he's under 40 blankets. Next the slowness, niw when I mean slow I mean every 5 seconds I get the pinwheel because it can't multitask correctly. I mean wow I can't even go to the apple in the top corner without it attempting to "load" the menu. even just on pages (which was a nightmare to download I'll get to that soon) Itll give me the pinwheel after a few words... App Store, broken. I tried to redownload pages iMovie etc. 40 clicks for each because they each showed an error occur.. Some right when I click some when it was downloaded... 1.99 GB and then it tells me it can't install... Then, it's a nightmare to log in because start up take 5 to 30 minutes depending on how ever much this machine wants to infuriate me. It's only 7 months old, there is no excuse for this, and I'm very disappointed, now before I take me and this machine to geek squad located in Best Buy can anyone locate with any knowledge why this thing is behaving so disturbinG. Please excuse the horrible spelling, I had to do this on my iphone and download google chrome because Safari doesn't support apple community When asking questions.

Your storage device is probably faulty. It would be helpful if you indicated the EXACT model/year MBP that you have.
Ciao.

My internal hard drive is making "clicking" noises

Hi there,
I have not been around for a while and I see that everything has changed... anyway... for a while now my harddrive is making noises as if it was being accessed all the time. There is plenty of RAM available, but still...
Latterly I have been having problems with Firefox as it is sucking all my memory, but I believe my issue with the harddrive making noises is quite separate.
Not quite sure what other info might be usefuk... except from FF, I don't have any process taking up too much memory. The only thing is kernel_task that now is at 335MB (I don't remember it too be so high).
TIA

Again, make sure you have everything fully backed up. The AHT isn't considered all that reliable. If you get an error, it can be trusted. But no errors, not necessarily. Did you run it in Extended?
Smart Utility, linked above, may prove to be a more thorough check, and you won't be wasting time testing the memory. I would run that.
Also, open Activity Monitor in Utilities. Switch to System Memory. Down at the bottom what does it say for Page outs and Swap used?
It's also possible the noise is coming from a fan. Get iStat Pro to check the fan speeds and that they are running normally.

Can you locate what part of the computer the noise is coming from?

MacBook drive keeps making eject noises

Hi
A key fell off my macbook earlier this week so I took it in to get it fixed. I got it back and the superdrive doesn't work.. it just makes eject sounds and buzzes like trying to read a disk...
If I try to put in a disk it feels like there is one inside, but if i put it in while it makes the eject noise, it goes in and is readable but makes noise like something is touching the disk..
Anything I can do to fix it? Thanks.. this is beginning to look like the rev a MBP I had

Lets just say I opened it and there was an extra clip (the ones on the right side beside the superdrive that hold the case on i think) ontop of the drive putting pressure on it and taking that out lets the disks get in fine
No I never damaged it

My CD drive keeps making strange noises when macbook first turns on or wakes from sleep

Any ideas?

It started a few months ago, but I got the macbook about 3 years ago. It seems that it doesn't make noises when there is a disc inserted, but when it's empty it does (very embarrassing in a quiet library!) - it's almost like it's satisfied when full of food, but it rumbles when it's hungry. Any ideas?

CD / DVD drive making funny noises....

Not the most tech savvy of posts I know, but when I insert a DVD disc into my drive, it just whirrrs, and clicks, and after about a minute, spits it out.
Any ideas??
Thanks
MArk

The drive is making funny noises because it's trying to read the disk. If it can't read the disk, it will spit it back out. Try wiping the disk from the center out with a cloth to remove any fingerprints. Hope this helps!

Apogee Duet & iMac digital Noise in speakers

This has probably been discussed already but I'm gonna add my 2 cents anyway.
Here's the setup. iMac with Apogee Duet using logic pro.
Powered speakers connected to the Duet with balanced cables.
60hertz noise floor problems not a factor.
With this setup I kept getting this medium hi pitched digital noise from my
speakers when the iMac was on and the Duet was connected to the firewire 400 port.
If I put the iMac to sleep then I would get a low pitched kind of digital gargle.
If I shut the iMac down I would still get the same low pitched kind of digital gargle.
If I ran the same setup off my MacBook Pro and ran it thru the paces i got no digital
noise of any.
After reading some other post about this issue over the past few days I decided to
try what others suggested even though it was hard to believe. I tried it because I
decided shut down the iMac and unplug it just to see what would happen.
When I did the noise went away.
So here's the answer. I bought a three prong to two prong converter. You know
one of the things you use to plug into a receptacle that isn't 3 prong. .75 cents.
I then plugged the iMac into the converter which in effect eliminates the ground.
I then plugged the iMac into the receptacle turned on the computer and you guessed
it. "NO NOISE". no noise at all period.
If you already knew about this then your good to go. If you didn't then there you go.
I didn't believe it when I read it but It really does work.

I am getting a 1 KHz whine through Behringer Truth monitors using M-Audio USB Fast Track Ultra audio/midi interface with an iMac i5 27-inch with LED monitor. The whine occurs continuously from the moment I open Logic Studio or iTunes, when the output is routed through the Fast Track Ultra. The whine does not occur when I use the imac output to imac's speakers. I also get an electronic scraping noise when I use the blue tooth connected magic mouse. I have installed ferrites on the monitor speaker wires with no reduction in the whining noise or electronic scraping noise. I have also ordered the USB with ferrite collar to see if the connection between audio/midi interface and the imac is the source of the noise. I am considering a Hum-X, as well, but I am getting into serious money taking stabs at a problem for which there ought to be plenty of competent technical support. The fact that this whine is at 1 KHz and not lower suggests that I am not suffering a typical ground loop. I am a former Pro Tools user who never had a hum or whine from my Digi and G4, which I am seriously considering recomissioning so I can make music again. I am spending way too much time and money making educated guesses and trying to diagnose a problem that all but kills the utility and purpose of this new system. I too am calling on all great engineers to step up with a diagnosis and solution.

I have an older macbook pro and the hard drive is starting to go (making loud noises). i tried to back up to an external hard drive (my passport essential se) using time machine and the computer keeps shutting down. suggestions to complete backup please?

Sounds like you'll need to access that drive while it is not booted. You need to replace it anyway, so do that, then one way or another (ext enclusure, et), access it and copy files.
If you keep trying to boot it, you might kill it for good and not get your files, so just swap it out first.

Optical drive is making noise

The noise that it is making, sounds like its reading the disc and then makes eject noises and it repeats the process twice and stop. But it won't let me insert a disk in, is it broken or jammed. this problem just started two days ago when I was inserting a disk and then it ejects, i have tired inserting a dvd, cd, software program and then result to making the noise. so I restart the computer it started to make the noise describe before. so every time It wakes up it makes the noise.
I dont want to have to take it to an apple store, to get it resolved. I want to know if theres a way first before taking it in.

When ever a problem has to do with a "hardware" situation, i ALWAYS suggest bringing it into the apple store. The only thing i can think of is that it is jammed. If you have recently dropped your MacPro then its a possibility its broken. I would suggest not trying to insert anything into the slot drive ever! Even if you opened your mac you cant get to the optical drive. The only solution would to take it in.
Hope this alittle. - Nate

IMac hard drive making knocking noise

Hi everyone. I woke up my iMac this morning, and the drive was making a knocking noise. There would be three "knocks" over and over again. Behind the noise, I could hear the whine of a motor speeding up, and then dying down. It repeated in a cycle: the motor winding up then dying down while three knocks could be heard. The computer would not wake up from this.
Finally, I rebooted with the install disc as a startup disc. When the computer turned on, it did not show the internal hard drive at all! I rebooted again, and this time the computer fired up just fine and everything was back to normal.
I've started backing up everything to an external drive. But I'm wondering: Is it time to go shopping for a new machine? This one is about four or five years old. I assume that if my hard drive is bad, it's not cost-effective to have it repaired. Is that correct?
Oh, FWIW, I did check the internal drive with the Disk Utility, and the SMART status said it was verified. (I don't know what this means, but I read about it online.)
Thanks.

Hi Roger. You were right about the pricing. I could have had a nice, much larger drive installed for about $279. But there was one thing that gave me pause: The screen was starting to show random lines and artifacts - all signs of the well-documented iMac display problems. Fixing that would have been a much more expensive proposition, and I decided a four-year-old machine wasn't worth it.
So instead, I backed everything up to an external drive and ordered a new 27-inch iMac, which is great. But while waiting for my new machine, I had to keep my old one alive. I noticed that the drive had problems waking up after the machine was asleep or off for more than a few hours. When this would happen, I would boot up with the installation disk and run the Mac hardware test. The test never detected any problems with the computer, but for some reason, just running the test (in the extended, 10-minute mode) would "wake" the hard drive back up.
After a few days of this, I came up with another solution. I just turned on iTunes and left it playing all night. I turned off the sound, so I didn't hear it. With this app running, the hard drive never went completely to sleep, and the machine would wake up every morning.
When my new iMac arrived, I connected it to my old machine (after waiting a few more days for a 800- to 400- Firewire adaptor - I didn't know the two machines used different Firewire connectors!) and I used Migration Assistant to move my data.
And with that, my old iMac died! It wouldn't boot up again at all. But it was still a good machine, and I didn't want to toss it. So I ordered a new 500Gb Seagate HD online for about $45 and a set of Torx screwdrivers. Using my new iMac to watch a Youtube video on how to replace the drive in the old machine, I swapped out the drive. The old iMac is now my kitchen computer, which I use for reading news, cruising the web and listening to iTunes. It doesn't need a large drive, since it's just used for light duty. And since it stays pretty cool (I'm not using it a lot or running CPU-intensive apps on it), the display problems so far have not reappeared.
Thanks again for your help!

Ibook g4 won't go past gray screen, hard drive making whirirng noises

I think I'm in pretty serious trouble here...
I left my 2-yr old ibook g4 running last night downloading a couple of torrents, and woke up in the middle of the night because it was making a loud whirring noise. I tried to close everything, but found that it was frozen. So I just powered it off. I've never had it freeze on me, or otherwise had any problems with it before.
When I turned it on this morning, it would make the initial startup chime, but would not go past the grey screen with the apple. I tried several times, with a couple of slightly different results. The first time I got the apple with the circle underneath. The second time, I got no apple, but the circle with a line through it. And the final time, its just been the apple. And all the while, the hard drive is making a really ill sounding whirr.
I read another post about trying to boot from the install CD, so I inserted the CD & pressed c, but nothing happens, and now the CD won't eject.
Is it possible that it overheated? I got an e-mail about the battery recall, but according to my serial number, mine wasn't one that was being recalled.
Please help!
iBook G4 Mac OS X (10.3.9)

Haven't had any replies yet, but I do have some progress to report...
I was able to eject the Panther Install CD1 after all (pressed the eject button immediately after I powered on). Have tried booting from it a couple of times, to no avail. I was, however, able to boot it from my friend's Tiger Install DVD. I went into Disk Utility, as I have read elsewhere and tried to repair my hard disk using that, but got the following error:
"Repair disk failed. Could not unmount disk"
Probably a stupid question, but is it because its not the correct operating system?
I still don't know why it won't boot from my Panther CD.
I have tried to boot in Safe Mode, but all I get is a little folder icon that alternately flashes the finder icon & a question mark.
I purchased my ibook online when I was still living in Canada, but its no longer under warranty and I didn't purchase the protection plan. I am currently living in rural Japan, with absolutely no Apple Stores anywhere remotely close to where I am.
I've also seen elsewhere that I could probably just get a new hard drive, which is fine as I could use the extra space anyway, but does this mean I lose everything that's on my current hard drive??
If anyone has any suggestions, it'd much appreciated!

Optical drive making squealing noise

all of a sudden my optical drive is making a high pitched squealing noise. also i've been able to burn dvd+r and now it just spits them out. i've had my mac for less then two years. this is my first mac (pc user for years) i really hope its not breaking down already. any help would be great.

It does sound like a fault with the optical drive. It is the noise that bothers me. I would still try clearing the pram if you haven't as yet (hold down applealt+pr while booting up, and wait to hear the 3rd chime before releasing them) and possibly resetting the SMC (unlikely solution), but that would not account for the noise.

Why is my disc drive making loud noises

why is my disc drive making loud noises when i am burning a disc?

Honestly, Its normal when it makes noise when a CD is in there.

Super Drive Making weird Noise on start Up

My super drive makes a weird noise when the computer starts up, is there anyways to turn off the drive and prevent this issue?
http://www.youtube.com/watch?v=Xyo7rPjxRRw
I have a Macbook pro Mid 2009 15in

Perfectly normal on many MBPs. There was a firmware update a while back that was supposed to eliminate the noise (which is simply the drive checking to see whether a disc is inside it). Some people reported that the update stopped the noise, others that it stopped the noise on waking from sleep but not at startup or vice versa, and others that it had no effect at all. For me, with a late '08 unibody, it stopped the noise on waking but not on startup.
Some other users have reported that inserting a CD most of the way into the drive while the computer is on, but pulling it out just as the machine began trying to ingest it, stopped the noise for them. I haven't tried that, because the noise doesn't bother me and I don't like the idea of fighting with something the drive is trying to do.

Digital noise using Apple 10-bit uncompressed codec for NTSC, BIG PROBLEM!

I hope someone from Apple or the Shake team can shed some light on this problem we're having so we can take the appropriate corrective action ASAP to meet our strict deadlines on this current project.
We're compositing all the EFX (over 1000 EXF shots) for a massive video game project that needs to be delivered to the client by the end of May. Let me preface the following comments by saying that overall, we're very pleased with Shake and the end results we're getting, but one problem in particular has us very worried about making our deadline:
The project is entirely bluescreen with CGI plates, shot on anamorphic Digibeta and captured into FCP as uncompressed 10 bit. 4:2:2 through a Blackmagic HD Extreme card (via SDI).
All the 4:2:2 material exhibits (for lack of a better desciption) digital "noise" that runs along the right-hand edge of the video, with frequent drop-out "looking" sparkles that can appear anywhere in the video image. These artifacts ONLY appear when the video clips are imported into Shake, and rendered out of Shake. They play perfectly fine in FCP and QT player.
If we force the FILE-IN node to 8 bit, the problem goes away, but keying suffers - so this is not an option.
The problem ONLY occurs on our Intel Mac's, not on our older G5's. The reason we invested in the Mac Pro's for this project was to reap the performance boost we desired in order to get the project out the door by our deadline, plus the G5's are busy offlining upcoming episodes - so turning the compositing over to the G5's is also not an option.
We're already well down the road, and while we realize that at Shake's current price-point it seems silly to complain at all, we gladly would have paid more for a compositing tool if we knew we were going to run into a situation like this. Unforunately, our initial evaluation of Shake was done on our G5's which don't suffer from this issue.
If anyone from has any recommendation for an efficient way to solve or work around this issue, we'd love to hear from you.
Best regards,
Michael Buday

Not sure the exact answer, but some options to try:
1) have you tried converting the clips to image
sequences? Perhaps it's a QuickTime error.
2) How about using 2 FileIns - one at 10 bit to
generate the keys and one at 8 bit for the fill?
Patrick
<img</div>
Hello Patrick and thanks for your suggestion:
We're going to experiment with different codecs and image sequences this week to see what happens.
RE: using different FILEIN's for key/fill, is something I hadn't thought of but unfortunately the 10bit FILEIN would still be affected by the noise which would in turn affect the alpha channel created by Keylight or Primatte.
I'll let you know what we find out as things progress.
Again, thanks.
