Volume and Pan Small Boxes Gone

I used to get small blue boxes at the tops and upper right and left sides of my music events , now i can only move them from left to right.

the top small blue box was for volume and the top left / right hand sides were for pan

Does anyone know how i can get them back?

Don’t you mean the fades and the volume control on your events? Those are only on selected audio events.

You may have made some events into parts?

Thanks guys, It only works for audio events not midi
