No sound output with Dubler trigger but ok with mouse trigger

In Logic Pro X I see the midi note on the piano roll being triggered by Doubler 2 but it produces no sound. When I click with the mouse there is sound. How to fix this?

Hi Gorbz,

Can you let me know what your setup is? Any screenshots can help us figure out why you’re not hearing sound

Is the instrument track armed in Logic, and receiving input from Dubler? Are you able to record the MIDI notes and does this playback okay?
