Sounds like an output midi lost a content input style. about groove2groove HOT 1 CLOSED

Normally only the harmony is preserved from the content input. Neither style nor the melody of the content input is preserved. This is why I'm adding the content melody to the output.

To achieve what you want, you could try to interpolate the styles of both songs as described in section VI.E of the paper. You would need to feed both songs to the style encoder to obtain two style embeddings s1 and s2 and then "blend" them e.g. with s = 0.4 * s1 + 0.6 * s2 and feed this s as the style embedding to the decoder. But note that this still won't allow you to preserve any specific parts of the content input, e.g. there will still be no melody. All the model will try to do is come up with an accompaniment style that is in between the two.
