So, using the RNN, the output file had repeated sections of ~20 notes from these individual midi files in this repo. You can run this, but you only have a small number of midi training files here, so, I'm currently trying WaveNET (https://github.com/ibab/tensorflow-wavenet) to see if it can learn from few observations (official release by DeepMind expected soon @ https://github.com/tensorflow/magenta/tree/master/magenta/models/).
Did use Magenta's basic_rnn the other day: samputnam.org
At $3/day, General Purpose SSD (gp2) provisioned storage - US East (Northern Virginia), this AMI is no longer public.
