Elektron Musical Instruments

Hello out there
this is maybe a stupid question but probably the easiest way for me
to solve the problem 
which is following:
MD connected via midi out to computer.Now for example i create a midi
track with the MD 
that controls lets say a synth in Reaktor.Strangely it seems that not
only the midi track 
sends MIDI data but also the other tracks on the MD which f... up the
thing I want to 
hear.By the way I tried to disable the MIDI output of the other
tracks which resulted in a 
bigger problem namely the MD not having any output of the individual
tracks 
anymore.Anybody got a solution?thanx
