Simply Music. Made because I found Chrome Song Maker too simple and FL studio a bit too advanced(still good though). And that's why I made Simply Music!
Simply Music is a self-contained HTML(downloadable version coming soon) document. And it has the basics of music makers: It has a piano roll, a timeline, AND it was made in Turbowarp(this is not a basic of music makers). It is also still in-dev. But will receive at least(if not) monthly updates. Bug fixes during the month, and YOUR ideas at the end(or in) the next month.
This was a challenge for me as I did it in Turbowarp. The worst was the timeline. And now its the save/load functions! Luckily, Turbowarp has cool extensions. Helping me make it. And I hope you enjoy it as much as I did making this for you!
