Hi folks-

I'm shopping for a basic controller to use with Logic on a Mac G4.
One thing I'm confused about is the practical difference between
just motorized faders, and motorized touch-sensitive faders. My
understanding is that when you touch a touch-sensitive fader, that
alerts the DAW to start recording moves on that fader. But with
a motorized fader, I presume the DAW records any *change* in the
fader setting, i.e., the controller sends a message when the fader
is moved (and not just when it's touched). Is this correct?

So then, what is the practical difference between the two moving
fader types? The one difference that occurs to me is that presumably
with touch faders you can *overwrite* existing automation---i.e.,
the DAW can play back moves, but as soon as you touch a fader, it
knows to start recording that one and overwrite previously recorded
moves. Is this the only difference? Is there a way a controller
with just motorized faders can overwrite (e.g., by sensing that
the fader is "grabbed")?

Thanks,
Tom
