Yes, but not like in the video.

The morphing I want to do is not just morphing using an x-y-pad.

It's more like morphing from a certain point "A" towards a movable point "X" on a kind of sailcloth that's clamped between 4 or 8 points like this http://www.lisori-sonnensegel.de/tl_files/lisori_referenz/lisori-sonnensegel-referenz_21.JPG in a coordinate system in which every possible point is a certain sound.

The points B,C,D,E span the sailcloth and A is an outside point. Point X is a movable point on the sailcloth like the point of a laserpointer that hits it. It defines the end-position of the distance A-X that is the morphing path.

Every point represents a parameter set that results in a certain sound and all possible positions X can be, are sharing aspects of all edge-points B,C,D,E in a certain ratio to one another.

I want to know, how this curved sailcloth and the point X on it can be calculated and how to move X around.

Is there a mathematical equation that describes that anyhow?

Sorry, I couldn't exaclty say yesterday, what I try to find out...I haven't been sure how to articulate my thoughts so others understand me.

You believe that experts know, but they only believe they know and know you believe them! This you should know!
