In light of the iPad Pro release, I just thought I'd mention my new music app. 
In short, it's a musical notebook designed for jotting down quick song ideas and working on your rough drafts — a kind of "living staff paper" that you can use almost like a drawing app. You can extend your notes to any duration and bend them to any pitch, allowing you to create twisted solos and complex rhythms with ease. All the controls for editing and playback are right there by your fingers, eliminating the "UI fatigue" that tends to set in with most creative music software. There's a regular paid version as well as free Lite version if you'd like to try it out!
Tangentially, I've also been doing a series of blog posts on its development, currently up to 3 and with many more to come:
1. http://beta-blog.archagon.net/2016/02/05/composers-sketchpad/
2. http://beta-blog.archagon.net/2016/02/27/path-rendering-in-composers-sketchpad/
3. http://beta-blog.archagon.net/2016/03/24/liberating-pitch-and-taming-midi-in-composers-sketchpad/
Thanks for looking!
