Hi
I am just starting my 1st HD recording project. I spent about 3 months learning my Mac, trying to learn PTLE 6, toying with my MBox.My system consists of the following: PowerBook G4 Ti (867Mhz), OS 10.3.3, PTLE 6.4, Edirol PCR-30 kybd contrl, a 250Gb USB 2 HD (via cardbus adpt.) and some MA-20D monitorz.
Now, I got everything all plugged in and running, started a new session to lay down some acoustic guit and some strings using SampleTank and when I begin to play I get this horrific static! i mean it's bad! I can't seem to quiet any of the gain stages enough to cut it out. I know I'm new at this, and maybe I don't have it set up right, but I just used the "Stereo Mix" option when I made the new session, and I haven't changed any of the Bus stuff (Don't know what that does, really) Sometimes it works for a while, then all the sudden BZZZZZZZ!!!
Anybody know what I've done wrong or how to help me?
Maybe I just need to take a ProTools class or something.
Any help would be so very appreciated!

While I am still new to DAWs and recording, I've run into a similar problem when my audio output was not set correctly. I believe you need to set the Mbox to receive output in Protools as well as in Sound section of the System Preferences. i am also running PT6.4, Panther, and the Mbox.

I think its when the Mbox sends a signal that tries to play through the built in sound output that the feedback buzz kicks in.

Anything deeper than that I can't tell you. Still figuring it all out here, but hopefully thats all it is. Good luck.

One thing that may help is to mute the track you are recording too. Also when tracking - i am on a TiBook too - disconnect the mains it helps cut down the noise floor a little. It should be pretty silent.
Check out the Digidesign User Conference too - very helpful

Well, I was able to record my acoustic guitar parts. I muted the track I was recording to and instead monitored my playing from the Mbox's headphone jack. The track sounds good, but I want to be able to use a 'click' and when I set up an aux track w/click insert I get the same problem with the feedback again!

I must be doing something wrong here.
Can someone please walk me through a hookup/configuration of the hardware I have? Maybe my monitors are plugged into the wrong jack or something?
Once again, any help would be much appreciated.
Thanks,

The only suggestion I can make is that the headphones output is coming almost straight from the input - 'hardware monitoring' - and so you won't get your click track that way.

I don't have an answer to the static problem, I'm afraid.

You might want to try fiddling with the settings in the Audio Midi Setup utility in the Utilites folder (OS X 10.3.3). In particular the Format setting in the Audio Output panel. This seemed to be the solution when I had similar issues with static.
