Elektron Musical Instruments

This is quite an instrument! Unfortunately I do not have nearly 
everything figured out. My question today is this:

When recording patterns using the sequencer, I am having a difficult 
time figuring out how to make my keyboard play the patch selected on 
track #2, or rather any other track than the patch that is on track 
#1 (I have the module Monomachine with a MIDI keyboard hooked up). I 
figured out that by using the bus selector AB I can get the triggers 
on the module itself to play the patch, but how do I get my MIDI 
keyboard to do so?
