Please help. Problem arming Logic pro 7 with Mbox1

[sonic76]

I am using a Mac book pro with an Mbox 1. I have installed Logic and recently installed new drivers for my Mbox and midiman. Everything seems to work fine until I arm an audio track. When armed it goes off the meter with noise as though too much gain is being put through. It seems to have nothing to do with the levels from the Mbox or any external hardware and only ceases to create noise armed when I change the Audio drivers to Built-in. Do I need to be changing something in the prefrences??????

 

Thanks

Open Audio/MIDI Setup from the Utilities folder in the Applications folder. Make sure you're not using the Digi drivers for basic system audio.

Thanks for the reply. Please excuse my ignorance but the only reference I can find about Drivers in the Audio/MIDI setup is on the MIDI devices page as part of my configuration where it shows my IAC Driver, Network, USB Midi, ect icons which is set to Default. On the Audio devices page it shows four fields, Default Input...., Properties For...., Default Output.....and System Output and then at the bottom Audio Input and Output. Is it a selection in one of these fields?

 

Thank again

Yes: set both default out and system out to "built-in".

Thanks for the advice. Unfortunately though this is what it was already set as. Any other ideas for this very frustrating problem????

 

I have also tried changing the Default input but with no joy.

 

Cheers

Check the sample rate for Logic and Mbox are the same... I had this on my 002 where for some reason Logic was set at 512 samples and the 002 was at 1024... result was white noise... just a thought...

Cheers for your response, unfortunately still no joy for this increasingly irritating problem!!!!!! any other ideas would be greatly appreciated.

 

Thanks
