Cant hear External midi Keyboard

Hi im trying to use My Octatrack as a master sequencer of a Digitone. But also use an external midi keyboard. As i find the Octatrak keyboard limiting.

I have the following:-

Out On the Octatrack to In Of DN. A
Out Arturia keylab to In on Octatrack

Midi Chanels 1-4 on Octatrack correspond to 1-4 on DN. Out puts from DN are going to inputs on DN

Autochannel is the same on the octatrack and midi keyboard.

So I can sequence the DIGITONE from the Octatrack. Here all tracks.

But I cant here the external midi Keyboard. when I press a not a a small dot appears in top corner near bpm but no sound.

Is there anything else I need to do to hear the midi keyboard?

Thanks clive

Solved! was all correct. Problem with keylab. Had to save auto chanel on keyboard to User 1
