So good to be true. A music making "app" or "software" I don't know what it's called but It's free, you don't have to download it, everything is in there, it's a website but it requires registration but it's not a problem if you have google account. Just 2 flaws are you can't use real instruments but only synths unless you have a sample you can cut, edit and arrange. Not talking about sample presets by the way. And you need a good RAM to prevent or minimize lags. Here's my screen shot of it. I've been making original music with this thing.
Oh yeah you can make Dubstep, Trap, House, Future Bass, Synth Wave, DnB or other Electronic music in there.
