MOTM

hello:
i seem to recall a discussion a week or 2 back regarding midi to trigger 
devices and there was talk of the kenton pro-kadi. i looked into one of these 
and ended up not buying one because it seemed to me that one had to install 
the d-sub like connector to whatever one wanted to trigger. now i know that 
this makes sense if one is trying to trigger one unit (say a tr-808) but can 
this unit be used to trigger say....several modules ? i was unable to figure 
out how. i hope i'm wrong. thanks in advance.
regards,
anton
