Re: musicXML: 2 staves, piano

Hello Dmitry,

It looks like you’re struggling with the tools instead of going ahead using 
them. 

What kind of programmed scores handling are you aiming at? There are various 
ways, such as python-ly (https://pypi.org/project/python-ly/), ABC notation 
(https://en.wikipedia.org/wiki/ABC_notation) or Humdrum **kern, see 
http://kern.ccarh.org. 

If LilyPond is the answer, much can be done with Scheme.
