You are correct that you can not change the type of font because there are fonts that will not work correctly so MTU chose one basic font that does. You stated it was too small. You change change the size of the font and you can change it to Bold or Italics. This is all you can change, but you have to change each one of them. After you have made your choices then click OK too get back to main control and click either Apply or Close and this will make the changes. If you click on the 'X' then no change is made. Same thing with the Color change. No change is made until you click Apply or Close in upper right corner.
Remember though that as you increase the font size the fewer lines you can get on the screen. And if you make changes to the Lyrics Tab they will not show until you play a song and the lyrics screen becomes active.
