Hi Dave ,
Update . I got it to recognise the sx, came up with Warning, this instrument is not supported.
So unfortunately no.
Awesome, thanks Rikki. The chord tracker is amazing, and works very well ( not 100%, but close)
You go to song mode, and choose a song from your own library. I use my itunes playlists
choose a song, and the app analyzes the chords, and scrolls them for you, in real time, as it plays the track/song.
