Interesting stuff. Thanks!

Since this is a midi-cv convertor, it sounds like I need to overwrite 
the oldest note with the new note. This is a simple matter of 
maintaining an age counter for each note. And I don't have to worry 
about note on/off status because this is replacing the oldest note 
regardless. I'm thinking I need to pulse the gate output when the note 
gets updated.
