How are you EQing ?

Not really understanding your question but…

Here’s how I’ve been currently doing it (note you should be well familiar with the tracks you are working with):

Start listening to track you want to bring in on your headphones. Does it start with a heavy kick or low end bass? Mids and highs only? All of the above? How does the track you want to bring in compare to the one you are playing frequency wise? If for example they both have a solid kick drum well if you add one low frequency sound + another similar one at the same fader level you get something like +3db volume increase (sound theory here), which is undesirable. So one of them should be reduced to accommodate the other. So, you are already beatmatched up, you lower or kill the Low EQ on your incoming track (as example but you could do it the other way round), pull your headphones off, begin fading up the new track to about same level as playing track, then slowly (or abruptly) lower the Low EQ on track 1 whilst raising the Low EQ on track 2. If you time it right the frequency range of one track replaces the other without an increase in volume level.

You can do the same with mids and highs as well. Swap out one for the other. Sometimes I got two tracks playing and I just swap out elements top to bottom. Trade one HH pattern for another (Hi EQ), one snare for another (Mid EQ), one kick drum or bass for another (Low EQ). Well, it’s a little more complex than that if you want it all to sound super sweet but you get the general idea. Nina Kraviz does this extensively which you can see/hear here: http://youtu.be/xogJgUteDAs

what genres are you playing?

simple rule to follow is balance them out to keep consistent volume, unless you want a melody or vocal to linger on through a mix.

I play trance (uplifting)

I hope this makes sense.

what I do is roughly this, but I do break from this if it would work better…

with an existing track all at 12o’clock bring the mids and highs up of the incoming till you can hear them, and the from that point you need to take out the mids and highs out to compensate for the incoming, which you get to 12o’clock

then I would change the bass (a complete swap from nothing to 12o’clock and 12o’clock to nothing on outgoing track)
then it’s just a case of fading the outgoing track, or cutting it completely when you change the bass
changing the bass is “The Drop!”

you can also use the channel fader, and have already set the initial positions of the eqs.

each stage of the mix is timed to suddenly change on the 1st beat of a 32 or 64 beat phrase or to fade in by then.(in the case of trance… other genres would vary ie hip-hop, which is almost a 1 bar transition.)

for some videos on this: Johnathan aka DJ Tutor / ellaskins has some good ones up.
search on youtube for “ellaskins eq”

If I read the OP right, there seems to be an idea that you use EQ to get your mix to be beatmatched. This is NOT the case, obviously.

There are two seperate things:
1) beatmatch. getting the tracks in sync. this you do regardless of EQ
2) transition. replacing the playing track with the cueued up track. here is where EQ usage comes in (as the others have said in their replies)

So, when you are watching DJ’s turning EQ knobs, they are doing this during a transition (or preparing for it), not to get the songs to match beats.
