How do you guys master your songs on the 4K?

Is this possible?

I wish the MPC4000 had a master track so you can apply compressor, EQ, etc to the final output of all the tracks. Is there a workaround?

Anyone here doing all the production on the MPC or do you export all your tracks to Logic, Sonar, or some other hardware DAW for mastering?

The 4000 is basically all I use for production nowadays,but after the beat is done I track it in Pro Tools. The 4000 is a moster,but you still should track,and mix your beats properly. I seriously doubt any upgrade is going to come that'll add a mastering function. Besides the effects in the 4000 suck anyway.

a master track would be sweet
I miss it sometimes to add or remove certain frequencies on the whole mix. an eq on the main part can really pump things up
