Crackling and Static using Logic Express on MacBook Pro

I plugged my UX1 into my MBP and hear very bad static and crackling coming from the UX1 headphone output.  I am using Logic Express 8.  I can choke the gate down and get rid of most of it but there goes my sustain.  Any thoughts?  Thanks,  Don

    Re: Crackling and Static using Logic Express on MacBook Pro

    First make sure all your drivers are up to date. Keep running Line6 Monkey. You'll need to reboot then run the Monkey over and over until no more updates are shown. If that doesn't fix it read on.

     

    I had the same problem on my MBP with my UX2. When I ran System Profiler (Finder->AppleMenu->AboutThisMac/->Click on "More Info") it showed the USB port as being USB 1.0 speed (12 mb/sec), not the high speed USB 2.0 speed (480 mb/sec) the UX2 needs.

     

    Line 6 says not to use an external USB hub, but that is what fixed the horrible cracking and popping and other noises for me.  I put an external powered USB 2.0 hub between the UX2 and the Mac's USB USB's input. The sound immediately cleared up, I even have other stuff on the 2.0 hub (an iLok key, external keyboard and track ball, iPhone dock...). None of that seems to interfere at all. The sound is now excellent.

     

    Maybe Line6's drivers and hardware are not kicking the MBP's USB ports into USB 2.0 high speed mode. The Mac seems to think these Line6 devices are USB 1.0 instead of the USB 2.0. So it reads and writes the USB port at too slow a speed and the signal breaks up.

     

    I hope this works for you. Good luck Don!

      I've tried 2 different M-Audio FastTracks - both were flaky.  I returned the last one after 1 day (no more Pro Tools either) and got the Pod Studio GX1 - works flawlessly right off the bat - I wouldn't touch anything M-Audio had their hands on after all the hair pullin' I went through.  Really wanted it to work too as it came with Pro Tools 8 Essentials but I got terrible sound no matter what I did.  I have 2 other inerfaces so I do know how to set one up - one is my $500 Boss GS-10 and this little GX1 sounds every bit as nice and Pod Farm is a whole lotta great amp sim software considering I paid $99 for it.  I'm a Line 6 customer now for life.

    I had the same issue and I found that it went away by 1) plugging it into a 2.0 usb port then in podfarm I went preferences>hardware>tonedirect settings and changed the bit rate from 16 to 32bit and buffer size to extra large. Give it a shot!
