4.6.5
It's a really good piece of software. Admittedly, it is a bit hard to learn at first, (like a lot of good software) but there are tutorials out there and once you learn how to use it, it becomes a very powerful tool for musical notation. The piano sound is adequate, but the strings and guitar are ridiculous. I don't even know what that "violin" is anymore. Thankfully, though, there are sound plugins you can download from the Musehub app (in my case, a Steinway piano and strings that sound like strings). Overall, a very nice app and I hope the team continues to update it over time.
