This app is good, but I think you ought to improve several things in order to satisfy my desire. Firstly, I want this app to include more time signatures. Currently, there are only 3 time signatures available. I want to see an option in which you can create your own time signature. That would be absolutely spectacular.Secondly, I would like a bug to be fixed. When I play the piano in GarageBand, sometimes the piano doesn’t produce equal sound as other notes (I tap on the keyboard with equal strength). If this bug is fixed, it will make my music-making more efficient.If you can achieve what I have suggested, I would be very grateful and happy, and I would give this app 5 stars. I look forward to seeing the improvements in action.😀😀😀
