I have tried the following experiment.

1) Get one of your .ly files and process it.
2) Get the .midi output and process it with midi2ly
3) Check them

Result: they look very different

Another issue how do use the options in midi2ly, in particular the key
option ACC[:MINOR]

Can anyone provide an example with the syntax?
