I don't know if you have max4live, but also, it has the feature of letting you have knobs on a channel which might be assignable to damn near anything in the set.
So you'd maybe have an 8 knob assignable device on the Master, 4 of those are tied to EQ on deck a, four on deck b, and then you just make sure 'select channel on clip launch' is deactivated.
But really, for djing, Push alone is not ideal. The relative aspect of the knobs is terrible for djing. The default of those jumping from channel to channel, the lack of any faders, and the reliance in its default state of jumping and hurdling your way through screens to control, volumes of several tracks at once, sends, channel parameters/knobs/EQ.
Push's grid plus that Novation controller would be heaven. Although I still wouldn't entirely rule out the Traktor Z1. The Z1 has one more bonus in cool-factor. It can also be used to control Traktor on iphone/iPad. I'd only recommend that if you Have an iphone or iPad (Traktor on iOS is beautiful!!). And then if you happen to have an iphone or iPad, you can also consider one of the many apps available for controlling Live

(although not as much tactility as would be preferred for djing, yet still doable).
