I am getting in the console the errors on line 56 and 111
lineNumber: 56 columnNumber: 20: Error calling method on NPObject!
The adapted .js is at https://raw.githubusercontent.com/abudaan/JazzMIDIBridge/master/lib/JazzMIDIBridge.js
I have no idea what the problem is and you are certainly more familiar with the jazz plugin than I am. I am thinking it must be the adapted .js library?
