I am very new to Guitar Pro and music theory/notation in general. I have a pdf with some music that I want to input into Guitar Pro, but it seems like the time signature doesn't match with the notes in bars. Is the file wrong or am I not understanding something?
The reason the notes and time signature seem not to match up is that there are two separate "voices" happening simultaneously. This idea is discussed in Too many notes in this measure and linked Q&A.
To identify the two voices, just know that the dotted quarter notes are one voice, and the eighth rests/notes are the other.
GuitarPro allows for multiple voices (up to four) using the Edit -> Voices menu. Can I put different note lengths on guitar pro (in one bar) discusses this and includes a link to the GuitarPro help center.
