MOTU 828MK2 picking up MIDI sync noise from Emagic AMT8???

Probably not an actual Logic problem, as it happens anytime an audio application 'initializes' and contacts my AMT8, but since theres no forum for the AMT8 Apple swallowed up from Emagic, and the drivers only come with Logic, figured I would ask here..
So recently Ive noticed my MOTU 828MK2 picks up the digital noise whenever I send MIDI sync to my AMT8 MIDI interface. If I sync just the MOTU's built in MIDI ports, nada nothing its dead quiet.. The minute sync goes to any port on the AMT8, theres that clock noise coming into my monitors (thankfully it doesnt go into Logic).. Ive checked the back of my desk and nothing is anywhere remotely close to my monitors cabling, the AMT8 is rackmounted literally right under the Furman power strip its plugged into and the adaptor is all by itself sitting right underneath. Tried a new USB cable plugged into different ports even, still picking up that noise.
It has not always been like this, Ive just noticed this behavior within the last few months so Im not sure where to go from here.. If anyone has any ideas of what to look at it Id be much obliged..
HW specs if it matters:
Mac Pro 1,1/OS 10.7.5/Logic 9.1.8
MOTU 828MK2 (Firewire)
AMT8 (USB)
All using the current drivers and latest versions of whatever they need to..

Have you tried initializing the 828MK2?
What's plugged into the AMT8? Have you tried removing MIDI cables one by one and testing?

  • Remove Noise from Video Breaks Sync

    I recently removed some audio noise from a video and the audio lost the sync with the video. Any ideas on what might cause this, and how to avoid it?
    I have 8 files I need to clean up, and obviously not breaking them would be best.
    Thanks!

    Hi Wes,
    Can you describe what happens a bit more? Is the audio late or early? By how much? Does it get worse over time? Does it appear out of sync within Soundbooth or only after you export it?
    Thanks,
    Durin

  • I had an iPod Classic 5th Gen that I upgraded from 30gb to 80gb.  The problem I'm having is that it will not more than about 5.4gb worth of songs.  The iPod begins to freeze mid sync and the (-69) error message haults the sync.

    I had an iPod Classic 5th Gen that I upgraded from 30gb to 80gb.  The problem I'm having is that it will not sync more than about 5.4gb worth of songs.  The iPod begins to freeze mid sync and the (-69) error message haults the sync process.  The hard drive has been upgraded, it has a new logicboard (with 128mb RAM), new housing, battery, hold / headphone jack.  Basically the only original parts are the bezel, click wheel, screen, and data ribbons. Have attempted the 3Rs and have also tried to isolate potentially corrupt audio files and remove them, but this did not seem to be the primary cause.  The sync failure consistently happens at just under a 1000 songs (5.4gb) and then it starts to error (-69) any song after that.  Your advise would be enthusiastically received.

    Here is what worked for me:
      My usb hub, being usb2, was too fast. I moved the wire to a usb port directory on my pc. That is a usb1 port which is slow enough to run your snyc.

  • Apple TV disappearing from iTunes in mid-sync (completely repeatable)

    Just in the past week, my Apple TV and iTunes aren't talking very well anymore.
    When I start up iTunes, it finds the AppleTV and tries to sync the latest TV show episodes I bought. It gets about 1 and a half episodes in to the sync, then suddenly the AppleTV disappears out of my iTunes and the sync stops.
    If I try to view the TV episodes on the Apple TV, it says "The selected video could not be played. The format was not recognized." (clearly, it really did stop in mid-sync).
    If I restart iTunes, it still doesn't find Apple TV. I have to reboot my MacBook Pro, then start iTunes again. Then it finds the AppleTV and syncs for about 5 minutes again, then quits...
    Completely repeatable and very frustrating. Nothing (movies, music, TV shows) can sync properly if it takes more than 5 minutes to sync. No other issues (can watch trailers and YouTube just fine from AppleTV, nothing else stops working on MacBook).
    All software is completely up to date at the latest version;
    Any suggestions?

    Thanks for you help and suggestions. Unfortunately, I tried all that a couple times ...
    - tried "Change iTunes Library" from the source menu and entered new passcode (it appeared in itunes for one minute, then dissapeared again) - tried that quite a few times
    - tried changing the name of my aTV
    - tried ethernet instead of wireless
    - did a factory restore (thinking maybe it was the youtube update)
    - started it all from scratch (like i just bought the thing)
    It only occurred to me, after reading Ramiro's post, that these issues appeared after the 7.3.2 update; i was smooth sailing beforehand.
    keep in mind that i'm a little paranoid when it comes to installing software so i always "fsck -fy" and fix permissions before and after.
    After smacking my head a few times, I rolled back to 7.2 and everything works like it used to.
    The only thing I'm certain about is that I'm gonna check this forum before I update to 7.3.3. What a headache that was.

  • Macbook Pro 2009 Mid year  making noises from top right corner near the cd

    I recently got my macbook pro and on the second day i begun to hear a noise from the cd drive like a scatching sound or like a disc was playing without anything being in there. I brought it to the store within a week and they said it needs a new logic board. I only had it for a week and its been in repair for almost 2 weeks. Is this normal? Im getting a feeling that my computer isnt new or something. Can i ask for a new one or is it to late? im having doubts now.

  • HT1296 My phone is picking up all my photos from my computer when I sync it and then running out of space - any ideas how to stop that?. Want to download not upload!!!

    My phone is uploading photos from my computer when I sync it - any ideas how I can stop this and remove what it's uploaded already?? Edit functions on phone won't delete the uploaded albums :-/

    Connect the iPhone to your PC/Mac with iTunes open.
    On iTunes do this:
    - go to summary (left hand side)
    - select the option photos to the right
    Here you need to decide how you would like to set how your iPhone syncs photos from your PC/Mac. Its is up to you wether you only want to sync selected or all photos. Once you have made the changes select "Apply" to the bottom right.
    Hope this helps

  • Audio/MIDI Sync Errors

    After working perfectly for months, I now am getting audio MIDI Sync error messages. The result is no audio output either from audio instruments or recorded audio. I am using a MOTU 896HD and audio thru itunes works as long as Logic is not running at the same time. If I switch to built in audio it seems to play back fine.

    Stever,
    There's a few posts on this over at the Sonikmatter forums.
    Two things were recommended.
    Toggle the internal clock to ADAT then back to internal.
    If that doesn't help, unplug the unit (electricity and firewire) then toggle the voltage selector switch, (putting it back to there it was of course).
    After doing this, flip the clock to ADAT then back to internal.
    The idea is to reset the unit.
    Post back if this works...

  • I recently downloaded the latest OS update and now I have a constant "humming" noise from my MBP and my audio output is no longer working. Any suggestions?

    I recently downloaded the lastest OS update (Lion X 10.7.4) on my MBP that I purchased in November of 2011, and since downloading it my MBP has been making a constant "humming" noise from the right speaker/disc drive area. I also don't have any audio output for FaceTime or Skype. I attempted to use Photo Booth to record a video and it doesn't record any audio. I attempted to reset SMC and reinstall Lion with no resolution of the problems.

    Click the Finder icon on the Dock.
    Applications > Utilities > Audio MIDI Setup
    Built-in-Output
    Output tab
    Move the Master volume slider to the right a bit.
    Best.

  • Digital Audio Noise from the Headphone Jack

    I have been searching for a while to see if anyone else has this problem.
    I have random faint digital noise (bleeps, bloops, and whirls) from my headphone jack. This happens regardless of application. I can get it going good by just tossing the volume bar back and forth on the sound pref panel.
    I have considerably less of this from the line out but still detectable noise.
    I have disconnected everything non essential from the Mac Pro and my power outlet are reduced to a minimum. (monitor and Mac)
    I have tried numerous headphones including Etymotic ER•6 and Sony MDR-7505.
    This has always been present in 10.4.7 and 10.4.8. Like I said, its faint in volume - but it gets annoying!
    I have read the following below and believe these do not apply to me because this is not an external powered device.

    I found out today what is causing the noise on my Mac Pro!
    Our next door neighbor has a really high power HAM radio that I am picking up static and transmissions from. I thought I was going insane when I heard weird voices coming out via my headphones. I know it is our neighbor because I heard him relay his name and location. Had to get my wife to listen to prove I was not going crazy.
    Here is the weird thing. I do not have AirPort or BlueTooth on the MacPro...so I cannot figure out how the transmission is permeating the Mac. Could it be a shielding issue on some internal component?
    Thanks!

  • Why I can't hear any noise from my earphones connected with my Mac?

    If I plug in my Earphones, my MacBook shows that my headphones are connected and I also can control my music with the buttons on my EarPods. However, I cannot hear any noise from them. What is wrong there?
    I have already checked everything in the settings and the Midi setup but it still does not work.
    What can I do?

    Hi ..
    You've checked System Preferences?
    Open System Preferences > Sound then select the Output tab.
    Make sure the correct device is selected.

  • MIDI sync dropping btw Logic8 & Doepfer MAQ 16/3

  • Weird Noises from Macbook Pro

    Some Weird noises from my MacBook Pro mid to late 2014

    Maybe you could describe what kind of "weird" noises you are hearing? Everybody's perception of weird is not the same, and something that you may think is weird may have a logical explanation. But we can't even begin to diagnose it without a little more to go on....

  • Can Logic plug ins remove background noise from interview?

    Can Logic plug ins remove background noise from interview?
    A friend with an important interview recorded in noisy conditions has asked me to help remove background noise - never done this technically.
    Is there a Logic or third party plug in that would could remove background noise from a spoken word interview? Have tried EQ which improves the sound slightly but not a solution.
    Anyone with specialised knowledge of this sound editing operation?
    cheers

    There are several 3rd party denoisers, they mostly work by first 'learning' the noise footprint of the audio, for which it is best to record a few seconds of silence (with an open mic).
    These will all do a decent to excellent (it all depends on the source material) job:

    http://www.kvraudio.com/get/1029.html
    Addit:
    Is it that background noise (traffic, talking etc) drowns out the words? Then you'd probably have more luck with (radical) eq-ing and/or notch filtering to find the most dominant frequency range of the speaker in relation to the background noise.
    As an interviewer myself I will point out that even with a small disctaphone you need to have some awareness of how the microphone picks up things. As soon as you nead to lean towards whoever you're talking to, just to make sure you're audible, the dictaphone on the table is probably recording mainly ambient noise, the interview being part of that. This is especially a problem when interviewing in a busy public space.

  • Why is iTunes not able to pick up certain photo folders from iPhoto? Camera and image sizes are similiar to the ones which can be picked up.

    why is itunes not able to pick up certain photo folders from Iphoto. i'm tryin got sync certain iphoto album into my iphone 5 but itunes is only able to read certain photo albums. not sure why because photos were taken using the same camera 1 day apart.
    pls advise.
    Thank you

    i did but its still only picking up some of the photos. For eg, 1 folder had 147 pics but iTunes is only picking up 17. Can't seem to understand why. They were all taken on the same day using the same camera with the same settings.
