Hello all,
 Since list traffic is a little slow today, I thought I would ask this
question:

 How do you route the final output of a complex patch?

 In larger patches, there may be three, four, or more "sub-patches" 
contributing to an overall sound. How do you go about combining all of
the aspects of a patch like this?

 Do you cascade a number of mixer modules to handle all the elements
of a patch, or (taking into consideration the 10v levels) do you send
individual patch elements to an external mixing desk?  Both, perhaps?

 Thanks,
 Andrew Sanchez
