Setting up sampling workflow on Mackie 802-vlz3 help me!

[ngyagi]

I have a bunch of sample sources that I want to route through the mixer into this chain: MPC1000>KAOSS PAD 3>SP404SX Then back into the mixer to allow me to monitor on a pair of KRKs and headphones. I have read the manual, but I'm not quite understanding how to get this set up. I don't think an aux send will work, cause I don't want a mix of wet and dry at the end, just a monitor mix of what comes out of the Sp404sx at the end of the chain. I have a feeling that the Alt3/4 might help me here, but I am getting confused about the routing of outs and ins to avoid feedback. I've attached a sketch of the routing I'm after. Can anyone help?
