I believe the ergonomics of a DJ mixer are good for
those who need to make very fast cuts in realtime, but not necessarily any different for
simple crossfades or EQ tweaks on a number of channels. The other advantage of using an
external controller talking to software is you can keep the quality of your D/A converter
if you like the way it sounds, rather than using the electronics in an analog DJ mixer.
the nice dj mixers do have a good signal path and adjustable crossover curves but nothing
that cant be done easily with software, but i really doubt the fader in a UC-17 or
something is any good, at that price point. i have a behringer, and opened it up and
lubricated the faders with mineral oil which helped quite a bit but they still slide
nowhere near as smooth as a RANE dj mixer.. i noticed you can buy replacement RANE faders
for like $50 a piece or so, it might make sense to just get some of thos and plug into a
multio to convert the CV into controller data...
