Horn Line Loops

Welcome to the forum.
I tried it out (having never used the loop construction view before).
There is a pitch button, then the key the pitch was recorded in, then a number box, set to 0 by default. Changing the number in that box raises the pitch of the clip.
You can also insert a marker in the timeline and designate what pitch the clips will be in following that marker.
I learned something new, too.
 

It works.  Thanks.  There's more in this program than any one person can retain.
