I made again an experiment with a 4-hand-piece today:
First I recorded a midi-file from the Primo-Part and in the second step I played the Secondo-Part together with the midi-file.
It's much easier to play together with a real player, because there is no conductor for the exactly play-together... then some parts will be with much more precision.
...but I liked the result, because it is a wonderful piece. I hope, you enjoy it.
The original piece is for piano-4-hands.
