Thank you for your answer and sorry to not have been very precise.
I'm using Audirvana 2, and using my mac mini as Home Theater connected to my Panasonic TV. Thus, I need to use Remote Buddy to control different softwares (Plex, iTunes, TV settings, etc...). Thus, I would like to avoid using the mouse and keyboard to select the tracks in Audirvana.
ITunes in Remote Buddy has a file browser that allow to easily view and select the tracks. I'm finding a way to have the same for Audirvana.
Thank you for your help !
