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

Ok I found out what it was on mine, the track was muted but the yellow M wasn’t showing on the track however the M on the top under Transport menu was yellow so I clicked it and now everything works fine, the reason I didn’t think of trying that is because other instances of the same synth were muted, maybe they were somehow midi connected when I copied the same instance to other tracks.
