Requirements

the requirements for LegGo were few but very strict:
- Hardware reliability and sturdiness (because it has to endure the life on the stage of a touring musician)
- Software reliability and ease of use
- Good readability and screen contrast
- Portability 

Oh, and an important one: I had a very close deadline: in two week our tour would start.

This led to the most important decision: to use "stock" software already available as much as possible.

The finished product:

Intended usage:
When you turn on LegGO, it automatically displays the selected PDF file (we call it "setlist") in full screen on the LegGo monitor.  

You can Then  browse the pages back and forward with two pedals.

A pushbutton is provided to alternate positive/negative view of the page (i.e. black text on white background or white on dark), according to the lighting conditions of the stage.

Preparing the PDF:
You can prepare the setlist  (i.e. the multi-page PDF file that will be shown on the monitor) in two way: 

• You can create the whole PDF file on another computer then load it into LegGo with an USB drive
• You can use the PDFArranger software included in LegGo to build your setlist by drag and drop the songs files.

Note that while you need a keyboard and a mouse to prepare and upload your PDF setlist  to the LegGO before the show, you don't need anything but the two pedal to operate LegGO during the performance.
