Thinning Out MIDI Controller Data Seems Not To Work

I drew some curves in the Sustain (CC64) lane of a MIDI event in the Key Editor. I used the Pencil Tool.

This created a lot of control events. I figured that it was unnecessary to have that many, so I tried to “thin out” the controller data using the MIDI Thin Out function. Nothing happened.

Is there some secret to using this function, or does it just not work?

It works for me here. Probably you didn’t have too many MIDI CCs.
