Can made tab support to harmonicas?
No pueden armar una seccion para armonicas? soy de argentina y ak se usa mucho la armonica para el rock-nacional. Y tambien seria una buena herramienta de estudio para los que kieran aprender con este programa(UltimateGuitar)

Unfortunately for you, there is little or no support for harmonicas on instrument tablature. It would be written as vocal melody, probably.

Some Guitar Pro files might have harmonica layers
My God, it's full of stars!
