Does anyone have a music notation app for iPad that they'd recommend for jotting down piano music? I have one that works well for guitar, but it works best with treble clef (or bass clef) and tab. I don't think it does both treble and bass clef too (though I haven't really used it for music notation much so I could be wrong there). I expect Vanessa might jump in and correct me if I'm wrong here.
I've come across a couple of possibilities; Notation, which is expensive and looks like it's for writing full-blown scores; Prelude, which I'm not happy with so far (most likely a user issue though).
What do you use? Would you recommend it? .... Of course I could just resort to writing it on paper.
