I was looking at the AlphaTrack and FaderPort at a local music store. 

The sales person said that if the AT is on a particular track and you select a different track with the mouse, the AT doesn't change its focus to the track you selected with the mouse.  You have to move the focus to that track with the AT's track button.  He said the FaderPort will advance automatically to the track selected by the mouse, so it is a better choice.  (This would be with Sonar, if that matters.)

Was he correct about the AT not automatically changing focus to the track selected by the mouse?

Thanks.  That helps.

Considering purchase of an AlphaTrack for use with Sonar. 

With regard to the information shown in the LCD screen, I have read that it will display parameter info when using the 3 rotary knobs to change FX parameters. But is that the only info it will display? 

Let's say you have used the track advance button to move the AlphaTrack to a different track.  Will it display the track name that you typed into the DAW software ?  For example a track named "Lead Guitar" or a Bus named "Vocal Bus". 

Otherwise how do you know for sure which track you advanced to (or is there some indication in the DAW software itself that tells which track the AlphaTrack is set to control?)   Thanks.
