Instrument Limit in Logic pro

If you are about building big ’sounds’ in Logic, like e.g. a piano with strings, it’s necessary to set a limit to some of the instruments.
You can tell Logic, this layer (e.g Track 01) goes from C0 – F3, but I couldn’t figure our, how to tell it to go to F#3.
The halftone was the problem.
Every way I tried to write it, doesn’t work.
Well, now I’ve found a way.

Do not write it.

Just hit the start- or end-note – notaion with your mouse, hold on to the mousebutton and move the mouse up or down…. magical…
Some times Mac-solutions are too simple.
