But maybe more interesting is the re-harmonization function which means you open a midi file and then you can choose in between four different reharmonization techniques and it will generate variations based on the algorithm you have chosen. Which you can listen to and save.
There is a more limited Demo version that you can try out first.
To be honest I have not tried this application much but like the idea to try out ideas fast and that if you are doing music that can be translated into a piano score it is nice to have it printed as a score or saved as new midi files.
