wish for a studio set up

I want to make my MPC4k the heart of my studio. Considering midi; is the next set-up possible and workable?
(By the way: I'm not an MPC-user yet, until next thursday...
Midi-out of MPC4k:
1. Machinedrum and Electribe-EA-1
2. KorgKarma
3. NordModular and AccesVirusC
4. Scope-Board (Creamware pc-'soundcard')
The MPC is for sampling and for MidiClock; master-input for CubaseSX. I want to sequence and record things in CubaseSX (and WaveLab4.0).
Midi out of Cubase to midi-in of masterkeyboard (SupernovaII-proX).
Masterkeyboard (SupernovaII-proX) midi-tru to MPC4k (midi-in)
Does this work correctly?
Futher: I've got a USB-Midiman4x4. How can I hook this into my midi-set-up?

I think studio essential,have your MPC hooked up via midi to your keyboard,so you can sync your keyboard on mpc.Hook up you mpc via midi to your computer,so that you can sync in cubase.I dont have a USB midiman,but once you plug it in to your computer,you can set it to receive midi clock or mtc data in cubase,or other sequencing software.Having that many keyboards and modules,it would be studio essential to have a mixer,or in my opinion better a control surface,and a proffesional sound card.I used to have an ER-A myself,and that thing is nice when hooked up via midi to a keyboard,or your mpc.
