I have this app on my iPad. You can export your file from Ireal Pro in a midi format.
I have an an sx 900 but this should apply to other models as well.
- select Export Audio on app , select midi, export the file to Dropbox or other similar area
- load the midi file on a usb stick then connect to keyboard
- use song player on the keyboard to load it from the stick
- it will play like any other midi file , you can edit instruments then save it to registration
- the score function bring up the detailed score
- i can not seem to get the chords to show.
- you could do the above steps on Music Soft App as well.
There are also some interesting things you can do with Yamaha Chord Tracker app.
The ones I have tried sounded quite good.
