Welcome to GuitarPro.7 Webpage.
GuitarPro is a nice and affordable tool to write music, drum turnarounds, backing tracks and so on. It will also give you the opportunity to write your own music. On the other hands, it allows you, for instance, to export midi files to Logic ProX so that you can then finalise your work with a professional tool.
Working with Voices.
On the MacOS, the keyboard shortcuts are (cmd 1,2,3,4) and the Multivoice (cmd M).
Working with Drum.
Writing the drum with GuitarPro is easy. Just use voices like above mentioned. I use voice 1 for the high hat, voice 2 for the kick and voice 3 for the snare. The snare has three kinds of sounds that can be selected on the numeric pad (1, 2, 3).
More drum samples will be added from time to time.
