Tracking Out Softsynths Help!!!

Ok, somebody is about to give me alot of softsynths to use. I am using a MPC1000 a proteus and a esi. What I want to do is be able to move thru everything at a good work flow. I was thinking of using chainer to create multisamples and then sample them into my esi, but that seems like alot of work. I have cubase and I could midi everything up and I want to use the mpc as the master. In doing that I can't figure out how I can record the softsynths because they would be coming from the computer and now any hardware. I don't want to lose any quality, but I also know that is is only so much that my laptop is going to be able to take. Help me out

A bit of a late reply, i was just browsing trough some unanswered post when i found this.
i wrote a little tutorial on how to control multiple softsynths in Cubase Sx. It might help you figure some stuff out.
