Train my own music from the pirate of the Caribbean's theme song - 2

For a plausible result, this time, I tried to generate a music from one midi file, ‘He is a pirate’ of the pirate of the Caribbean. I thought if I made a music from the one source, I can get the more similar result with the original. But It was different from what I thought. The consequence was alike my last music. however this time, I found out that I can continue to train it. So I generated midi files at certain times, 10, 20, 30, 100, 180, 410.
And This video is for generated5(step100). And as you know, you can find It is getting slower than the first generation while the time is passing by.
