Pitchmap Free Download

Not sure how many people will be familiar with pitchmap but it's essentially a polyphonic autotune that can work on its own or via midi, and it's this secondary function that I'm having trouble with.

Native fl plugins like vocodex and fruity limiter have input/carrier boxes built in, but most third party stuff doesn't, so I'm not exactly sure how I'd go about setting up midi/sidechaining with pitchmap, in assumedly a vocoder style approach.
