more parts for instruments?

GPU support isn't working... :(

Using Theano backend.

well I will just give up :( I will try to use Anaconda then

The issue is caused by your Theano installation. I always used Tensorflow during my experiments so I can't really help you for this. If you use Anaconda, make sure you have the appropriate Keras version (there has been recent changes) so the code is no longer compatible with the newest versions.

For more instruments, it is in principle possible to generalize this model. Nonetheless, each part must be monophonic. There is a NUM_VOICES constant to set. Take a look at the is_playing metadata (in metadata.py) which you should include when creating your dataset (look how the --dataset parameter is used in deepbach.py).

I tested this on Monteverdi madrigals (5 voices) and it works quite well.
But if your dataset contains doubled parts, there might be some issues...

Good luck. I'm eager to see the results

hi, i used Theano and it quite works well on GPU.
as for more instruments, I meant polyphony style like Bach's cantatas.
