I cannot seem to get the app to interface with the piano. The app merely says I need a compatible digital piano. ### 1/5 — Doesn’t work *2019-01-18, version 1.1.1* Really disappointed, brand new Casio 870 doesn’t connect to either of the chordana apps even though it says it is compatible. ### 1/5 — Features don’t work with Privia PX 770 *2019-01-06, version 1.1.1* 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. ## Most critical reviews (10 lowest-rated) ### 1/5 — Just doesn’t work *2022-06-23, version 2.4.7* I downloaded the app and it fails to connect my iPhone to my piano. I’ve tried several variations of suggestions from the Internet And I continue to get “function requires a connection to a compatible digital piano.” **Developer response:** Thank you for using Chordana Play for Piano. We apologize for any inconvenience. Please see here for the connectable electronic pianos. https://web.casio.com/app/en/piano/support/connect.html ### 1/5 — Drains battery in background. *2022-01-21, version 2.4.5* In the first 24 hours of use, it was on screen for 18 minutes and had 16 hours of background activity, draining 44% of my iPad battery while it was locked. ### 1/5 — Px s3000 cannot connect *2021-07-15, version 2.3.4* I purchased because of this app and it will not connect! No help, no instructions etc. So upset **Developer response:** Thank you for using Chordana Play for Piano. We apologize for any inconvenience.

Not the case and no help to be found to fix this issue. What's the point of advertising Bluetooth if there isn't an easy way to connect? ### 1/5 — eps120 cannot connect *2019-11-10, version 2.2.2* because of iOS 13？ please fix the problem ### 1/5 — Does not recognise AP 470 *2019-07-17, version 2.2.1* I tried with iphone 7 plus, then an android phone, and in both cases it says “this function requires connection to a compatible digital piano”, then I connected to a notebook computer running windows 10, started musescore and was able to write notes on the staff by pressing the piano keys. Then I installed an android emulator (BlueStacks, then installed chordana play for piano via the emulator an ran it, got the same result. Tried again by changing the USB device mode to storage in all cases with no avail. ### 1/5 — Can’t connect *2019-04-10, version 2.2.0* Simply complains about needing a compatible piano, which I have (PX-870). Fails to connect. ### 1/5 — Connection error for PX-870 *2019-03-25, version 2.2.0* A connection error is displayed indicating: This function requires a connection to a compatible digital piano. Please fix. Thanks. ### 1/5 — Can’t connect *2019-03-25, version 2.2.0* I connected my phone to the new px-870 with the USB cable and the app just says that I should connect to the piano. Any instructions of how to connect? ## Most praised reviews (7 highest-rated) ### 5/5 — does not connect- YES IT DOES! *2020-02-14, version 2.2.3* There are a lot of reviews written about the app not connecting to the keyboard, or not recognizing it. This is because a lot of users use the wrong usb port. They plug it into the port that looks like a usb 2 charging port. This is actually the port where Casio wants you to plug in a hard drive. The other usb port that is more square is the one for connecting your iPad to. So it's not an app problem folks! ### 5/5 — Revised Review *2019-04-23, version 2.2.0* For those that have had connection issues, I suggest purchasing a Lightening to USS B all-in-one cable., rather than using a USB-A to USB-B adapter. My new connector (from Amazon) works perfect. Therefore I’m changing my previous rating of 1 star to 5. ### 3/5 — iPad mini 3 *2021-03-27, version 2.3.3* Please make compatible with the iPad mini 3 :’( ### 3/5 — This doesn’t make sense *2020-05-14, version 2.2.3* I’m trying to connect my keyboard to this app and I can’t figure out how it works. Do I have to plug something in? Or is it Bluetooth, because my keyboard doesn’t have Bluetooth so how can I use my iPad for the piano remote controls part it tells me “ this function requires a connection to a compatible digital piano. Please help me. ### 3/5 — Sustain does it work *2019-05-25, version 2.2.0* Using iPad 6th gen with iOS 12.3.1 and the PX S3000, the pedal sustain pedal does not work. After disconnecting the iPad, I must restart the piano to restore the sustain. I’ve tried changing the pedal function in the app with no effect. Otherwise app holds promise IF the sustain issue is fixed. ### 3/5 — Great potential, poor implementation *2018-04-30, version 1.1.1* 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. ### 2/5 — Does not connect *2020-07-31, version 2.3.0* Does not connect --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
