Please consider adding this feature. I just recorded a band with the CQ18T, the results were great, but having the ability to monitor multiple inputs at once via the headphone output would have made the process much easier.
Thanks 
I use the outs of the CQ 18 to a Rane 6 channel headphone amp.
Still working it out but I think this will work.
Using it with LPX and I use the send on each channel and set the send to output 3 into the Rane HP amp (6 channels). You can also add additional send i.e output 4-5-6 and have up to 4 HP mixes. Still working out if I can use CQ outs 1+2 because LPX defaults to 1+2.

Just to bring this up again.
Especially in live situations it would be very usefull to have the possibility to listen to several channels togehter (e.g. to check the frequency distribution when ajusting an eq).
