Three things

Huge potential here! One thing I really like is that I can write plain note heads to sketch out ideas without having to commit to rythmic constraints in a given measure. Two issues though. First, the trainer is nowhere to be found. It’s not in the upper left hamburger menu. The other is the radial modifier for accidentals. It’s a bit slow-too many steps to change one note. What would be nice is if it could be left open when adding accidentals to multiple notes, or if multiple notes could be highlighted blue, then allowing all to be modified with a flat or sharp in one fell swoop.

Darn. I was really hoping this had drum set notation in it. I enjoy writing the music but I am a bit of a perfectionist and it takes me forever to write music out and have it look aesthetically pleasing. I thought great! I can use my iPad Pro and write out my drum ideas, exercises, and songs. Please create the ability for drum set notation and I will be back!

Komp 1.6 has a five-line percussion staff and percussion noteheads. We are working hard to add additional percussion staffs and improve alternative notehead entry. Thanks!

On a good way

So far the most professional handwriting notation on appstore suitable for ipad pro. There are many bugs, however so far. The recognition is probably the best amongst the other apps, however editing is somewhat impossible. Good start, I’m curious how it’s going to develop.
