Sound is heard when editing MIDI, but not when I press Play

edit: sorry I realize this might be an even different issue than this post was about


Mute unmute doesn’t work for me.
Monitor / not Monitor doesn’t work.

My midi in activity is not causing notes to fire, though midi activity registers in the lower right midi input monitor

In the process of trying to figure this out, the piano roll keyboard stopped making notes fire when I use the mouse on it. Super screwed I don’t know what to do.

Notes I enter manually trigger the vsti (exdrummer), and play fine on regular playback
but no midi from outside the box causes notes to fire, same for clicks from the mouse on piano roll keyboard.
