Headphone Mix With Ensemble, How to create headphone mixes with the Ensemble Options

[anamorphis]

Hi,
I'm about to purchase an Ensemble, and I've been reading the manuals and trying to figure out some things. I have a question about doing headphone mixes with it.
Let's say I have the Ensemble in the control room, and I would like to send two different headphone mixes to the live room, one for the drummer and one for the bass player. Can I use the insert sends to do this? What control do I have on the levels and what tracks will each listen to?
I use Logic 8, is this done inside Logic or is it an internal Ensemble software configuration?
And then, when using the inserts for this purpose, would I still be able to use the front pannel headphone ports separately, if needed?

Thanks a lot for your time.
