Play button won't work so you have to add the note Change notes is not being implemented, that a feature was unfinished. Hope you can remove it but unfortunately, you have to set over or click on green flag. You can change bpm and the note bpm as you want to change. You can get midi data by going to the editor and see it. Save MIDI and Load MIDI are beta features, which I even to do so, making as implemented feature, it will be any glitches in this project or something like that. Here you can change visualization for that piano midi, it has five types of visualizers so you try it. Remix if you want more notes, instruments, I supply a piano, but you can fix the bugs.
Actually the beta project is not currently finished because I worked a lot of time. Also I didn't come back because of hosting the servers (not Scratch, my own servers from other repositories).
