hi folks.. DSP Error in Display and no tone!

    Hello my friends,


    yesterday i stepped slowly through my prof illes and suddenly had no tone and the Display shows
    DSP-Error!
    Then you could still step through the profiles, but no response (Tone)!
    What the hell is DSP Errror? I never had this before!
    After rebooting everything's ok!
    I tryed to reproduce the error again without success, but
    something is not correct please notice this!


    I use the firmware 1.5.1.7803

    this happened to me once too, reboot worked and i haven't seen it again. iirc it was before update to v1.5...
