Notes not sounding when selected in Edit mode

[GroverGrooves]

This is weird. In most songs, when you click on a Midi note in the editor, it sounds out.

For one of my songs, this doesn't happen.

Is there a setting somewhere that might be distinct between songs?

Thanks.

Click the little Headphone icon in the top left of the MIDI net editor and the notes will play when selected.
