As in timecode control? You’ll certainly need to buy timecode vinyl and a new soundcard, one with inputs with a phono preamp, such as the audio 4.
I can’t see any reason why you couldn’t continue to EQ internally (though I’ve not tried it myself with time vinyl) so if you’re just mixing you could use the VCI-100 as a mixer.
However since you’re only talking about one turntable I’m assuming that you intend to scratch with it so you’ll most likely be wanting a quality 2 channel mixer with a nice crossfader rather than the VCI-100.
Actually now that I think about it it is perfectly possible to use one turntable to control multiple decks using timecode vinyl. You’d just have to set all the decks to one input and have buttons that switch between vinyl control and regular playback for each deck and juggle them about a bit.
