Live/X: Possibility to monitor all outs through headphones?

Hi,
say I have routed the mpc live so that I have different programs or tracks on the output pairs (1,2), (3,4) and two mono channels 5 and 6. I use an external mixer when I listen to my speakers. But what if I take the mpc to another place where I want to work on that same track while listening through headphones. What will I hear with the above routing? I fear it will be only channel (1,2).. am I right?

You'll only hear 1/2.

You could route the other tracks back to 1/2, and change them as needed when you get back to having a mixer... there's probably some sub mix or send/return things you could do so that 1/2 has everything, and then 3/4, 5, 6... are something else.
