Sending Note On Message with velocity 0

Use this script to make a note message with velocity 0

//$<AutoDeclare>
// DO NOT EDIT THIS SECTION MANUALLY
Var
   MIN : MidiInBlock
   BUTTONS : Widget
//$</AutoDeclare>


// Called when a single widget value has changed
On WidgetValueChanged(newValue : double) from BUTTONS
 if newValue == 1.0 then
 SendNow(MIN, MakeNoteMessage(C3, 0))
 Print(MakeNoteMessage(C3, 0))
 end
End

In the global MIDI monitor window if the sending instance this can be seen

In the global MIDI monitor of the 2nd GP instance I see this incoming MIDI message

So is that by design, that Incoming Note On messages with velocity 0 are interpreted as Note Off messages with velocity 64?

Yeah, when we did it, it seemed reasonable to use use an “average” release time, hence 64
