I've been enjoying and very appreciative of the Yamaha Music Apps. Ah, particularly those which were developed specifically for the Motif XF workstation.
& a few of those others apps as well. Very well priced considering what you get included with these apps.
It's convenient and very helpful where you can make adjustment to the keyboard from the large touch sensitive iPad screen, once your wifi is enabled from the Motif XF. Ah opposed to the much smaller screen on my Motif XF8.
Big Thank's to YAMAHA Corp music division!!
