This tool might be helpful if you just want a simple midi keyboard. I am going to download it to my laptop. When I am doing sequencing and just need a simple musical input, this will be extra useful instead of clicking all the way with your mouse.

This program should not be removed it teaches people who don’t have a piano and want to do it on the keyboard and also people that made this website might even look what you said and block you so uh yeah good luck.
