Topic: A question for voiceover user

is it possible to make piano studio accessible for voiceover?
I'm musician and composer, I'm working on sonar with screen reading software, but sometimes i'm not near my computer and want to save my ideas. I'm looking for some application and this is good. someone ask "but how to play with voiceover?" Yes it's impossible, but for example when I'm playing something without voiceover and make a mistake I can turn on again and edit the notes. So my question is: is it possible to label the buttons and notes in this application?
Best regards, Ralf
