Hi!
First, thanks for using IanniX :). Then, it’s a common problem that we never solved because it’s not so easy to create the right solution.
Maybe the best thing would be to put a trigger just at the end of the curve, this trigger can send “fake” cursor values (=> double-clic on the trigger to change its message, then select “Default OSC Message for cursors” and edit values). Is it an acceptable solution?
