I cant find a decent sheet music maker! Like my dad has garage band with keyboard, but it just doesnt work to well. I tryied umm noteworth composer, but it didnt have an instructions on how to get dma notes on the tab! Im looking to compose to elvish theme from lotr to piano! Please help

I've got a suggestion, but I'm not sure if it's... what you're looking for I guess.

I compose music as well. In school, they have a software called Sibelius.

You connect a keyboard to the computer, and Sibelius will record whatever you write.

It's not free. So yeah, I doubt this suggestion's helpful.

Although Sibelius is an excellent software.
