Hi Andrei, or what you might want to try for some better surface editability is to set the "# Points" (number of points) mode for the Profiles option in the loft.

That will do a rebuild of each re-seamed curve using the number of points that you specify, and because the rebuild happens after the curve seam changing, the lofted surface result with that option will have a simple control point structure to it.

You can set the "Point count" option that shows up underneath the "Profiles" option to adjust the density of the generated surface.

If you want to do direct control point editing of the generated loft surface that would probably be your best bet.
