Thank you for your feedback. It will be very valuable to me. Can I ask what browser you are using on your iPad? I guess Chrome will solve your problem on your iPad. I will try to look into it.
As you mentioned, this is a first step and the main goal is to help build muscle memory for common progressions. And also how chords solve into each other, not just learning the chords themselves.
With the great feedback I got here, I am planning to improve it so that more people can enjoy it.
Feel free to join the mailing list to get the updates.
But… I’ve connected my Yamaha P-515 electric piano to my iPad, and it doesn’t show in the app’s “MIDI keyboard” dropdown.
Lots of Googling comes up with nothing helpful - or understandable, at least, to me, a novice when it comes to MIDI.
I’m writing this feedback, not because I want tech support, but because maybe it is helpful that a keen would-be user simply can’t get started.
