How to map more effects on MIDI controler

Hello,
is it possible to map more effects on one MIDI controler?
for example, i have old UC16, Ive learned how to make it work with MixVibes 7 DVS, but i am not able to map efx1volume on knob1 efx2volume on knob2...
i can map all knobs on efx1volume but cannot make them to map separateli...
for example2... efx1 = echo, efx2 = filter (all on left deck1)
is there somebody who could help me?
