control vA2 time dependent with karaoke text

[tthoms]

Hello
I would control the vA2 over the controlers with karaoke information from a mp3 song. You know I can define with a mp3 editor the time dependent text that should be shown in the karaoke window.
For example.
[00:50.300]Show this Text[00:54.100]
will show in the karaoke window after 50 seconds for 4 seconds the text "Show this text".

What I want to do is now send only one character to the vArranger (not to the karaoke window). This character (number) will
activate the defined controler in vA2.

For example:  [00:50.300]6[00:51.100]
would send the number 6 to va2 controler and change the sound in the soundbar.
Have you any idea how to to that?
