From the developer: "Tab machine is a program to write out guitar tablature. It is simple, cheap and fast to use and includes an easy chord generator for speedy input of most chords and bar lines. There is a choice of open fingerings or barre chords. You can also input any custom chords manually. The file size is very small to allow for a fast download. A prototype of this version has been tried and tested by guitar players worldwide and updates have been made based upon feedback."
