M-Audio Fast Track
http://avid.force.com/pkb/articles/en_US/download/Fast-Track-Drivers?popup=true&NewLang=en&DocType=1450&q=Fast%20Track%20Drivers

This is the proceedure I followed to update the driver and firmware on the M-Audio Fast Track Pro

1. Powered of the M-Audio Fast Track Pro
2. Un-installed the old driver “M-Audio FastTrackPro 6_0_7“ from the Windows Programs & Features in Windows 8
3. Reboot
4. Install the new driver from Avid “Install_M-Audio_Fast_Track_Pro_6.1.10.exe”
5. Powered on the M-Audio Fast Track Pro and the new driver immediately prompted to update the firmware on the unit.
6. Reboot for good measure.
7. Open Samplitude and Restore default application behavior from the Help menu. (I did this just to delete any reference to the old driver settings.

After Samplitude restart I opened up one of the songs that had the most problems with the M-Audio Fast Track Pro and the problems were gone, no more distorted static or buffer drop-outs during recording.

Also after the driver and firmware update, I also noticed better input signals coming from the Fast Track and the wave forms do look much better with nice full sounding guitar tones also the effects work much better now that they have better wave forms to deal with. So glad the Fast Track Pro is working now, hope all holds well with the new driver.

Thanks
