Hey All,

     Logic 7.1
     OS 10.3.9
     Motu 8pre or MBox (1)
     Roland UM-2 MIDI 
  
     In a nutshell:  If I try to play audio tracks along with virtual instrument tracks, things get 
all choppy in the audio and I get a warning "MIDI and audio sync error recognized.  Logic 
recognized a sample rate of 41,231 recognized" or something like that.

      If I freeze the midi (virtual instrument) tracks, everything plays fine.

      Any clues on this one????

      I've tried different sync options in the sync transport button, the ones that looked 
promising "internal" and "auto-detect" or whatever that one was called.  

      Thanks for any insights!

Of course, you need to check that you are at a sample rate of 44.1 or 
whatever, and then check any audio files in use - and bounce them or convert them if 
necessary to make sure everything is the same and what you expect it to be. 
You might also try switching to the built-in audio drivers and see if the 
drivers are causing the problem. I had occasional problems with the m-audio drivers 
and the Native Instrument drivers (more where they produce (strong unwanted 
digital) distortion though).

However, I suspect that Logic is just bogging down. I think the truth of the 
matter is that it can't necessarily handle all that many plug ins and virtual 
instruments - especially things like Sculpture and Echoboy. I have had as many 
as 10 virtual instruments with 20 plugs, but sometimes I get those sync 
errors even with only a few tracks and few plugs.

You know,

     I was playing some virtual piano last night, in an empty session and had the same type 
of problem/sound.  I noticed thatthe sustain pedal seemed to be more of a culprit for 
creating my problem than anything else!  

      I still don't know the answer, but it's nice to have a clue into this mystery added.
