Wow, I didn't even notice this for Fader and Fader MIDI.
I'm on 10.4.5 but it was there on 10.4.4 as well.
You can't edit high values for FaderMIDI in the EventList but you can MIDI record the high values and they will store in the EventList as high values.
If you try to change it in the EventList, the max will change to 127.
