Apple Logic Pro /LogicExpress Discussion

Hey Guys,

     I had a Easter gig as a sound engineer at a church.  On my reference CD there were some 
tracks I created with Logic/iTunes, including a sine wave sweep.

     The track sounded okay at home but at the venue there was a TON of static/distortion on 
the tracks I created with Logic/iTunes.    The sine wave sweep made it sound like the higher 
the frequency, the more the noise.

     I can e-mail a file if anybody wants to hear.

    Just curious if anybody knew if this is operator error ... iTunes protective injection of noise 
to keep me from copying CDs ??

     I never had this happen with Logic 7.  I believe my output levels were okay.  The biggest 
puzzle is that I don't hear it in my studio monitors (KRK Rokit 8).

    Thanks,

Since it tested okay at home I suspect your signal chain at the church.. I'd examine the mixer 
settings which took the CD player output.  Perhaps the channel(s) trimpot(s) was/were set for 
mic level rather than -10 or +4 line level.  SOMEthing was being overdriven.

best luck

could be speaker distortion too, or a blown speaker.

My first suspicion was a bad cable or something in the system.  But when I tried a 
commercially made CD, no distortion ... only my CDs, and my iTunes burned copy of 
Nickel Creek's commercial recording distorted.

Sounds like I'm the only person to experience this though.

Could it be a clocking thing?  Recently I started being more interconnected with digital 
connections (MBox - Yamaha Digital Mixer - MOTU 8-Pre).  Sometimes the mixer displays 
a complaint about the word clock, and since it sounds fine here I disregard the warning.
