I needed to create an example of pitch and pitch confidence so I coded that (in Pd but hey translation is quite simple) - so here goes a random pitch version, with a twist 
What I found fun is the musical biases I baked in the code - a sample-and-hold in silences following a long large confident pitch. It was done through negotiation with myself, as I didn’t know that is what I wanted until I coded it and didn’t like what I heard. The question is, did I code the right, or the left condition first? Votes are welcome.
