[LAU] software for aiding piano practice?

[Csillag Kristof]

Hi,

I am looking for some (Linux) software that I can use to aid piano practice.

(Show me the score, automatically turn/shift the page, show me where I 
am, show me which notes I missed, maybe play the other (non-piano) 
tracks, that kind of thing.)

Can you recommend me such software?

(I know about a few windows applications, but I would really like to 
avoid using Windows.)

Thank you for your help:
