Display a box in the middle of the screen when you touch a touch-sensitive knob with text about that parameter. The box can be displayed as long as you have your finger on the knob. There may be a delay of about 1 second so that you can touch a knob without the text box appearing immediately. If you have not entered any text about the parameter, the text box will never open no matter how long you have your finger on the knob. It would be perfect to have access to information about all parameters without having to look in the manual.
I have tried LUA info.setText(text) but the text that can be displayed is too short and hard to see at the bottom of the screen.
