Logic Pro X all of a sudden can't detect input from M-Audio Mobile Pre

I was recording guitars when I had to step away for a while. I closed the lid on my MBP and left. When I came back, all of a sudden, Logic can't detect any inputs coming from my USB interface. I have tried everything from rebooting, switching to the other input on my interface, updating drivers, but nothing seems to work. What's worse is whenever I start Logic with my interface plugged in, Logic gets stuck at Checking MIDI Drivers. If I unplug my interface, Logic would start fine, but if I plug my interface back, Logic won't detect it.
I am using the M-Audio's input while I am using the Built-In Output on the MBP (I don't have monitor speakers). It was working fine before.
I am using a Mid-2012 MBP 15" on OSX Mountain Lion and an M-Audio MobilePre MKII USB interface.

In this exact order
1) Unplug MobilePre
2) Remove it's drivers using the uninstall routine that is in the Driver DMG image ... 
Note: If you get a message about it cannot uninstall.. Restart your Mac and then try to uninstall again...
3) Restart your Mac after you have uninstalled the drivers..
4) Reinstall latest drivers......
5) Restart Mac..
6) Wait until Mac has restarted and then plug in MobilePre...
It should then be correctly recognized and work....

  • I have a carillon 25 keyboard (bad choice, I know) and I can't get it to communicate with my mac at all! I'm running logic pro 9 and reason 5. I get signal in from my M Audio trigger finger so I know it isnt an entirely mac based problem. Thanks!!!

    Well, how have to determined no signal is being recieved to your mac?
    Have you got something that shows the actual signal? Or have you just been trying to control a VST? What software are you using by the way?
    I personnally went with a AKAI MPK25, because it's made already mapped for logic & ableton etc, so it just makes things incredibly easy.
    I would suggest you return it if you can as a dead unit & perhaps look at something else a bit easier?
    Otherwise, if you just want to get this working we can have a look a bit deeper.
    And driver? OS X driver?

    You can, for $199 - which is cheaper than all the previous updates.

    All of a sudden can't receive email on Mail client.  Sessions with service provider (att/yahoo) and Apple have yielded no results!  Recently upgraded to Lion, but have received email since.  Anyone having the same problem.  Apple says service provider problem, service provider say it's the mail client.  Anyone had this problem???

    No.  My frustration with the problem just led me to begin the process convert all my email to a gmail client.  However, after some time all my mail with att/yahoo has been coming through as before.  Go figure.  Still will convert to gmail.

    What do you mean it did not work!  What were the results of the diagnostic tests?
    Have you contacted your ISP to determine if the problem is on their end?  
    Have you changed your router channel?  Sometimes this resolves wireless problems.

  • On 3G we cannot send emails from either our iPhones or iPad and this also happens with some WiFi connections but not all.  Yet we can always send emails from our Hotmail Email account.  What is causing this and what do we need to do to resolve it?

    On 3G we cannot send  Business emails from either our iPhones or Ipad and this also happens with some WiFi connections but not all.  Yet we can always send emails from our Hotmail Account using both 3G and WiFi.
    We bought the iPhones and Ipad so that we could send emails while we are out of the Office, but we are not able to do this unless we can find a WiFi connection. Incoming emails are fine.  We use IMAP, for Business emails just incase this is relevant and I know that Hotmail is POP3.
    Our technical IT knowledge is not great, so we look forward to your suggestions as to how to resolve this. 

    Contact whomever supports the email account and get the correct Outgoing email server settings from them.

    Well...I went to the modem (Westell, WireSpeed), found the NAT settings, once again, I'm WAY over my head, I am assuming this is a TCP connection (as opposed to a UDP) and per Lorex my mobile devices will use port 1025.  So I gave it a "global port range" of 1-10 and I indicated that the "base host port" was 80, 1025, & 9000 (ports 1,2,3).  When I selected the 'enable' it asked for a "host devise" my choices are my IPhone, IMac and the IP address for the dvr, so I choose the dvr.  I still cannot connect and canyouseeme still can NOT find these open ports.  This is taking up my whole day! I don't know how people figure this stuff out.

  • How can i get input from user in Workflows

    I'm new to SAP B1 Workflow, i have created some workflows and they all worked fine.
    But, I am wondering, How can i get input from user?. For example, i want to display list of options to choose between them and route the workflow based on the selected option. I don't want to use the exclusive gateway and check for some conditions, i want to get input from user.
    How can i do that?

  • I connect my mic with an M-audio mobile pre usb device.  When I try to record, I can see that my voice is recording but can't hear it during playback.

    I connect my mic with an M-audio mobile pre usb device.  When I try to record, I can see that my voice is recording but can't hear it during playback.  I tried different input and output settings but it didn't help.  Any help will be appreciated.

    Hear your microphone or instrument as you play and record (monitoring)
    You can hear, or monitor, input from an instrument or microphone in GarageBand while you play and record. When you turn on monitoring for a track, you hear the musical instrument or microphone connected to the track’s input. Monitoring lets you hear yourself play so that you can hear the part you want to record as well as the rest of the project.
    You can turn on monitoring for a Real Instrument track or Electric Guitartrack from the track’s header, or in the Track Info pane. Electric Guitar tracks always show their monitoring buttons, and you can show monitoring buttons for Real Instrument tracks using a menu command. You can use monitoring with feedback protection to avoid feedback while you play.
    Hide
    To turn on monitoring in the track header:
    Choose Track > “Show Monitoring for Real Instrument Tracks.”Monitor buttons appear in the headers of Real Instrument tracks. On tracks with monitoring turned on, the button lights yellow.
    Click the Monitor button in the header of the track you want to use.
    HideTo turn on monitoring in the Track Info pane:
    Double-click the header of the Real Instrument or Electric Guitar track you want to turn on monitoring for.The Track Info pane opens.
    From the Monitor pop-up menu, choose one of the following:
    Choose Off to turn off monitoring. You can hear your instrument only while you record.
    Choose On to turn on monitoring and protect against feedback.
    Choose On (no feedback protection) to turn on monitoring without feedback protection. If the input level is too high, it may cause feedback (especially if you are using a microphone and listening to your project through your computer speakers).
    For an Electric Guitar track, you can view the Monitor pop-up menu by clicking Edit, and then clicking the back side of the amp. The Monitor pop-up menu appears with the input controls below the stage.
    You should usually turn off monitoring when you are not playing or singing. When monitoring is turned on, your computer can pick up output from your speakers or monitors, causing unwanted feedback. Using headphones rather than speakers to listen to your projects can help eliminate feedback.
    If you select your computer’s built-in microphone as the audio input, in the Audio/MIDI pane of GarageBand preferences, monitoring is turned off for all Electric Guitar tracks to avoid unwanted noise.

  • ( Can't detect panicbuf from physical memory list Program terminated

    Has anyone seen this error when attempting to install Solaris 8 on a Sparc 10. I receive this error when I attempt to ( ok boot cdrom (enter) )
    ( Can't detect panicbuf from physical memory list) Program terminated
    I think I am having a problem with my physical memory.
    Any ideas would be appreciated.
    Thanks,

    I'm banging my head because I can't find a solution to make my arch-install detect an audio CD
    I assume that you mean the optical drive. I don't see a /dev/sr0 in /dev
    Does it show up with lsblk or parted -l?
    Looks like it's a LiteOn drive.
    You can play an audio CD.
    mplayer cdda://
    mpv cdda://track[−endtrack][:speed][/device] −−cdrom−device=PATH
    An audio CD doesn't have a mountable file system on it.

  • Help Need-All of a sudden can't import/open .OMF file without Logic quit

    Hi all. Been a looong time since I posted but I'm back with a serious dilemma. I'm working on a short film with a deadline that's coming at me fast and furious. I just picked up an updated version of the .omf file and all of a sudden it won't load without logic quitting on me. What's going on? My Logic beahavior has seemed a little off but not noticibly disfunctional lately. do I need to toss my prefs? How do I do this if so? I'm always worried I'll delete something I can't recover...
    I think that's about it. Let me know if I need to clarify the situation. This all worked fine a couple weeks ago. I'm using the powerbook 15" template video for NTSC. I'm clueless now and really need help. THANKS!

    Nobody has any idea why this might be happening? Can anybody at least cue me in on how I should go about dumping my LP7 prefs and then replacing them or updating them again?
    thanks!

  • Why is my Macbook Pro slow all of a sudden?

    Question repost as the first question posted, only received one answer that did not assist at all, unfortunately.
    I have a 2013 Macbook Pro that i purchased earlier this year.  My second.  First one had 0 problems, ever.  I upgraded from 8 to 16gb of RAM, and it was running just as it should.  All of a sudden, and without any warning, it has slowed to a snails pace on just about everything.  I get the pinwheel of death constantly, it's taking 20-30 minutes to move 1.77GB of data, which used to take under 1 minute.  Programs are slow to open, and the stalling is constant.  I've read a few forums, and all signs seem to point to the beginning of a HD failure?  Can someone please assist?
    Sidenote:  i went and checked the disc permissions, which did show many errors, all of which, however, i repaired.  It started working again fairly well for a day, and is now back to the same level of slow.  What could this be?  Please help.

  • What Can Logic Pro 8 Do that LP 7 Can't?

    My question is... What will I be able to do with LogisStudio/Logic Pro 8 ( besides getting rid of the XSkey ), that I can't already do with Logic Pro 7?
    Is it really worth the upgrade of $199.00 to have a different GUI & no need for an XS key?

    It seems to have fixed a number of long-standing bugs. For instance, bouncing a track almost always ended up with a little glitch at the beginning of the bounced file. That's fixed.
    I've had my end-of-song marker move mysteriously for no reason at all. That seems to have been fixed.
    Waveburner actually can now burn CDs and you can use MatchEQ and multi-pressor with it. I believe a lot of people had trouble with it before.
    There is a 33 page "What's new in Logic Pro 8" PDF here:
    http://manuals.info.apple.com/en/NewFeatures_in_Logic_Pro8.pdf
    You should take a look at that. Not everything there is something you can't currently do - some of it is simplified workflow - but there are a fair number of new, but little features.
