I have Guitar Pro installed on my machine. Guitar pro is a software that makes sounds according to the tablature you open. I'm curious about a symbol that I don't know what it means. It's a tilde but in the bass; it seems a comma right in the middle, not in the left, between the two notes. Thanks for all.
It doesn't appear on the manual.
UPDATE 2: Probably the slide is bad printed because it's shorter than these. This is what it appears on the manual.
