Xpantastic!

Until recently I had my my Xpander on its own midi buss, but due to  
some setup thinning out, it now needs to share a midi bus (1 Midi out  
from a Emagic MT-4) with other synths but I cannot seem to set it  
correctly in single mode to receive on just one midi channel, it wants  
to respond to all channels, could someone please go over these steps  
with me please, I must be missing something. Thank you, e
