Changing tempo using midi clock

Hi there..I'm using Axiom pro 61... also using the playback plugin to play loops..I want to use my drum machine to send midi clock for tempo changes .( have midi out of DM connected to midi in of AXIOM). Besides checking "GET TEMPO FROM MIDI INPUT" what else should i do to have my loops change tempo when I change the tempo on my drum machine?..Any ideas? thank you!
(right now it is not working as is)
