Add an auto-play feature
Add a feature where you can listen to the song you are about to play played correctly by a robot. It can be very hard to keep up with the white ball, especially during fasts songs. It would be way easier to play to melody by hearing and repeating than to look at the ball all the time.
This has already been implemented. Moderators, please clean up the forum, when features have been added. Keeping suggestions around after implementation is counter-productive.
You can do this in Yousician. Go to Practice Mode and select "Play For Me". I don't know if this feature is still on Yousician, but if it was tooked away, I will vote for this suggestion.
