Static Overlays All Sounds After a Couple Stop/Start Playbacks/Logic 9.1.3

  • Recently upgraded from a G5 tower to an 8 core to make the jump from Logic 8-9 . After doing so a litany of weird issues have been introduced. Most problematic being that my Virus is basically useless.


    I can get several midi channels going via USB and everything is fine for a few stop/start playbacks. Usually after anywhere from 3-5 stop/start playbacks, the entire Virus gets covered in a loud static type noise that overlays all sounds being played- you can hear the selected patches barely audible under a very thick, low frequency static.


    I am assuming it is a hardware problem and its time to pony up for repair but wondering if anyone has had similar issues.


    Kit:


    8 core Tower


    Digi 003
    Logic 9.1.3
    Virus Ti version 1, recently updated firmware etc.


    Thoughts? Suggestions? Thanks for reading.

  • Hi Marc,


    Thank you for your reply. Yes I recently updated the other day to the beta version as I was previously on the release version.


    Was fingers crossed hoping that was the issue. :-\ Let me know your thoughts...


    Is there any way it is a cable/signal strength issue? IE, should I simply try a new usb cable for starters?????

  • okay, i guess we need some joint effort here. fact is that a few see this problem and we cannot reproduce it. so we need to dig deeper.


    - does it happen wir logic versions before 9.1.3?
    - does it only happen on specific macs (in other words, do all who have this problem have the same mac). we have 2 8-cores and it does not happen here.
    - are you using the virus as your sound card or a third party solution? if you use it as your sound card, does the problem persist when you switch to the internal sound card of your mac?

    Thanks Marc, yes I confirmed last night with a couple others who are having issues. My totally conjectural guess is this a port issue somehow.


    - I have an 8core 2.33 running 10.6. Audio Card is a Digi Rack 003. M-Audio Trigger Finger.
    - I noticed when a third external bus powered firewire drive gets plugged in, the 003 dies. This makes me think that the 8core is somehow not delineating power/bandwidth properly when its ports get really jammed up with gear...is it possible? I will test it when I get to the studio tonight.


    I started to wonder because a friend...


    - Has an 8core tower running Snow Leopard and apogee converters
    - He has Same issues on tower, no issues whatsoever with macbook pro running same os.


    Other users I have spoken too who also have quite full ports, but with less power/bw demands on each port (ie just iLoks and monitor switchers etc), do not have same issue.


    Let me know your thoughts. Thanks.

  • hi noah :)


    same issue here. mac pro 8 core 10.6.4 and 9.1.3 logic. happening on release version and newest beta. happening on all ports and when i remove all other devices, reflash firmware, permissions repair..everything. virus showing up fine in control center and fully functional unit i plug into a usb port, then freakout begins


    not happening on macbook pro core 2 duo running same firmware, Ti os and same version of logic...


    been emailing tech support and they have no idea what the issue is.


    this started happening when i upgraded to 10.6.4...was'nt and issue on 10.6.3


    no solution in sight!

  • Bobby!!! Thanks for chiming in man - Yes I also followed the same crib sheet you forwarded me from your ticket over the weekend and haven't had any luck whatsoever. Interesting it was not an issue with 10.6.3 - I never ran it on that.


    Marc, it would seem something went amiss with OS X 10.6.4 port assignments on 8cores, is there any chance of coordinating a high level fix with Apple based on the prevalence and general "fatal-ness" of the issue? I haven't heard of any other USB based music devices having this issue with 10.6.4 so it must be something very specific to the way a Virus talks back to the OS?


    Thoughts? We MUST get to the bottom of this! Thanks.

  • i believe there are loads of people using the virus with an 8 core mac and i guess most users are on 10.6.x right now. so we have to narrow it down further. please list the following information for me:


    - which 8 core are you using (model number, build date etc.)
    - is the virus your soundcard at the same time?
    - does it happen with the tutorial song, logic set to a buffer size of 128 samples?
    - does it happen with 10.6.5 as well?


    thanks, marc

  • hi,


    you need to contact support. we cannot replicate the problem here and the vast majority of mac users with new 8 cores seems to not suffer from any problem described above. in fact, pretty much everybody seems very happy with the last two releases.


    Zitat

    any news from apple on usb port bandwidth issues?


    which issue? there is no general issue as far as we know. you should work with support on a solution.

  • hi,


    you need to contact support. we cannot replicate the problem here and the vast majority of mac users with new 8 cores seems to not suffer from any problem described above. in fact, pretty much everybody seems very happy with the last two releases. vast majority of users are not pro users and don't push their devices.

    contact which support? access or apple? Are you serious? There are at least 50+ different threads on your forum with people complaining about inexplicable static issues. And multiple people on each of those threads confirming the same issue with 8cores...

    which issue? there is no general issue as far as we know -

    is it so hard for someone from Access development to make contact with someone at Apple development to sort this out? We are talking about a device that retails for $2,000 and is COMPLETELY USELESS for thousands of your users right now. You ignoring the issue on the forum or making light of it, as you are here, will not make it go away and does not shed any positive light on your company for being so aloof about it. It has been ongoing for 6 months...users are not crazy, something is amiss....users are not developers...users pay your company big money for devices so stuff like this gets sorted out by professionals with high level knowledge.

    you should work with support on a solution.

    which support? yours or apple?


    best, marc
