got a couple of synth modules, drum module etc and want to control everythin from my midi keyboard....

set up....

midi out of my controller to the midi in off the interface - midi thru of the interface to midi in of drum machine - midi thru from that to drum module and ive just repeated the process with the synths etc

so i think ive got that set up fine.... its just once im in cubase i dont know what to use for my ins and outs....

ive got 4 options for my ins.... microkontrol 1 midi in, microkontrol 1 port A, microkontrol 1 port B and saffire pro midi

for my outs.... microkontrol 1 midi out, microkontrol ctrl, saffire pro midi

what do i use? also do i need add input and output busses for each bit of equipment thats connected to the interface?

also how do i sync everything using the internal clock?

thanks in advance
