It wasn't a defective alphaTrack at all, it was the M-Audio keyboard that has a little volume slider. For some reason, it's volume settings would override all others. So I reset the m-audio, by just unplugging it, and dropping it's volume to 0.

Thanks for the help CS. I'll be sure to calibrate anyway. Didn't know how to do that before.



I've been loving my AlphaTrack for about 2 years now. Using it with Logic 8, it's been an incredible tool for my mixes. It's been 100% problem free... until now.

I upgraded to OS X 10.5.8 (From 10.4.11) and funny things started happening. Specifically, the fader will randomly jump levels (changing the instrument level in Logic). It is driving me crazy. There's a ghost in the machine who's hell bent on destroying my mixes!

Here's a .mov of the freaky behavior (notice the lack of automation in Logic):

Any ideas on how to fix this?
