perfomance rnn js demo with own midi material

[chrislos]

Dear magenta team,

thanks so much for all your efforts bringing magenta closer to artistic dudes like me.

I'm currently trying to port your performance_rnn browser model using tensorflow.js with my own trained midi composition.

I went through the whole conversion process and endet up with a (hopefully valid) midi -> training data -> squences -> performance_rnn.mag file including my composition data.

Unfortunately I don't know how to use this dataset with the tensorflow.js library.
Could you give me a hint at which place I replace my *.mag file with the current trained model? Or did I miss some deeper understanding here?

Thanks and greetings from Berlin,
Christian
