I don't own the T2 because I hate
not having the 76 keys.

As for sliders, I think the non-motorized sliders are more a distraction than a benefit. With motorized sliders the present position indicates the current setting for the volume. Without this, the sliders you have adjusted show the current setting, but the others are meaningless, showing how they were moved last time. So now you have remember which slider is in its true position and which one is in the old position - yet another task to do while playing.
