I have some questions about the Ketron SD40. I'm very happy with expander.

1.
If I have an additional screen for my fellow musicians connected, the texts of MP3s are not displayed. Do I have to set something apart? What am I doing wrong?

2.
We also work with a click for the drummer. If I lower the master volume slightly, the click of the drummer's ears will also be quieter. That's not the intention. How can I prevent this?

3.
Is the last update required to create the SD40? I now have version 1.1.0 (04.10.2014). The last update is still just an adaptation for using the accordion ?
