Crave Velocity MIDI with Ableton Live

Hi,


I am triying configure Ableton live and Crave with the purpose thaty the velocity of the notes I am sending from ableton affects to crave's velocity.


In Synth Tool I selected MIDI Velocity from Assing Value. I've been tryng through USB and MIDI port from audi interface but it doesn't work.


Must I do something with patchbay??


Thanks a lot
