On another note, pun intended. I noticed that showmidi doesn't clear hanging NOTE ON messages. It would be nice to have an option to clear these in the 2,5, or 10 second span. I use Note ON messages from rotary encoders from my Maschine controller to control some aspects of Cubase. If you turn right one click it sends G8, if you turn left one click it sends C-2. This is good for controlling the move playhead by the current grid setting such as BAR.
Thus I never get any Notes off for these notes, so they never auto clear.
