Export and print
Paper, PDF, and .gp for everyone you play with.
Print-quality PDF, or straight to paper
A4 or Letter, with margins, scale, which tracks to include, headers and page numbers — then write a PDF or hand the same settings to the system print dialog. The output is vector, from the same renderer that draws the screen.

.gp that Guitar Pro opens
Tonograph writes .gp. Before it does, it tells you exactly what the format cannot carry from your score — so nothing goes missing quietly.

Your own format
.tonograph is JSON: readable, diffable and yours. Auto-save and crash recovery use it.
