I've also made a few iOS apps for the purpose of simplifying composition, though they're pretty limited in scope (on purpose). Although it seems most composers would prefer to use full DAWs from the start, I'm personally much more creative when I'm able to jot down and edit my fragmented musical ideas as quickly as possible, if only to make the initial draft. (If I were a better singer or musician, I'd just use a recorder or a looper — but my skills aren't quite there yet, and besides, it's hard to note-edit a recording.) Composer's Sketchpad[1] lets you paint notes directly onto a time/pitch canvas, bending and stretching them as they go along. (This works great for e.g. guitar solos.) MusicMessages![2] is a more basic piano roll that lets users quickly tap buttons across several layers to enter notes. (Musical bubble wrap! Works great for riffing on short drum sequences and chord progressions.) There's another similar-sounding project called Helio that was posted a few weeks ago: https://news.ycombinator.com/item?id=14212054 https://news.ycombinator.com/item?id=14212054 I hope that in time, we get more Markdown-style composition tools vs. the full DAW suite. Good luck! I'm looking forward to seeing what you make. P.S. AudioKit is pretty dope. :) [1]: http://composerssketchpad.com http://composerssketchpad.com [2]: http://musicmessages.io http://musicmessages.io -- working on turning it into a full iOS app, so will probably have to shut it down and fold it into the new app at some point
