I tried to follow along with this tutorial, when I put the notes in the empty instrument track the trick doesn't work for me. it's not controlling UB and I'm not hearing anything and I have voice mute on in UB and nothing is showing in the monitor object in the environment.

Hi K1, Which tutorial are you referring to? Could you let us know the video number and/or name. Thanks Rounik

tutorial #57

Hi K1, I just tried it now in Logic 9 and it still works fine. Have you made the correct connections, e.g. Empty Inst track 2 to a monitor which connects to the UB channel strip? Does the MIDI region on Inst 2 have notes from C1 to C3 (NOT C -1 for example). Does UB have Voice Mute Mode switched on? If you follow each step of the tutorial I'm confident you'll be generating random UB patterns in no time :) Rounik
