Behringer TD-3 help sync with Uno Drum

I have been trying to sync my TD3 with my drum machine the Uno Drum. I have successfully connected them via Midi out of Uno in TD3. Channels set the same #1. Uno drum set to internal. TD3 set to midi. I want to be able to use the drums seperately while achieving a bassline from the synth seperately. But for some reason all im getting is the TD3s chords on my uno drums pads. Any advice would appreciated. Am i missing something? Is it not possible to clock sync with the uno drums clock? Do i need an external clock? I have seen videos on youtube of them working fine together. Cheers
