So, if you want to do anything interesting with slurs - like this:
I go into Engrave and I increase the number of segments in the slur properties. This give me three sets of handles to manipulate - the peak of each curve with two associated handles to manipulate curvature and length a la Illustrator (or similar vector program), and a handle for each end of the curve.
I’m finding It quite frustrating that when you manipulate any of these handles, it also manipulates all of the other handles - In Illustrator, or similar, I would position the peaks where I would like them, and then manipulate the handles manually until the slope of the curve was correct. As it is, as soon as you move one peak, the handles and sometimes position of another peak is moved, meaning I have to go back and manipulate a point which I had already set.
Is there a way to make this more intuitive and a little less faffy?
