then don't look at the FaderPort, as it has a motorized fader...
though... I believe (and I may be wrong) you will need a motorized fader if your goal is automation...as a manual fader will remain wherever you last left it... so as you scroll thru the tracks... the fader will not change position (if manual) regardless of what the level is in the mix
that was my main reason for getting a motorized console so I could automate multiple tracks, rather than one at a time with the mouse...
The Faderport will limit you to one track at a time, but you'll be able to change tracks quickly
