Great potential, poor implementation

While the Chordana Play for Piano app really does much to facilitate the process of changing settings on my PX-870, and also provides the ability to save four configurations and load them from the app, I find it overwhelmingly frustrating in other areas: 1) It provides the ability to play pieces with an orchestra, but the scores for those pieces are nowhere to be found; 2) The learning section provides quite a variety of pieces to learn, with most of them being Classical. The trouble here is that they don’t provide the notation for them, but use only a coloured piano roll with an onscreen keyboard to show what notes are being played. They really got this backwards, as this app’s content is predominately Classical, yet they provide only a piano roll; whereas, in their first Chordana app, which had very few Classical pieces, and was primarily nursery rhymes and pop, they provided the choice of a piano roll, regular notation, or both. Why, with a product geared towards serious players, would they limit the teaching section to something that serious players don’t use! 4) There is no mention anywhere in the manual or videos to explain how to import PDF files into the app. After asking on a Facebook group, someone advised me how to do it, which I had already tried on my own, but it doesn’t work on either my iPad or iPhone. I really like my PX-870, but this app is very disappointing.

Doesn’t work

Really disappointed, brand new Casio 870 doesn’t connect to either of the chordana apps even though it says it is compatible.

Features don’t work with Privia PX 770

I have a Casio Privia PX 770 and when I connect it to the app on my phone all the features on the second slide on the app don’t work, like the piano lid options or the string resonance. I they update the app or fix it, but for now I’ll give it one star.
