hey, I was thinking about how to do a graphic "knob" with this patch, but could not realize yet the correct trigonometric operation to do with [gemouse] transformations... Could someone give an idea? I though in something like the edge of the angle stucked in the mouse pointer, but I don't know Gem or geometry enough to realize it...
the starting point is attached... thanks glerm
