>Even my concern that it was tied to an app that might disappear one day is of course covered by the fact that it's all just MIDI files on a card.

I was sorta surprised when the blog mentioned it was like 200k lines of code for an app. I wouldn't think you'd even need an app for something that puts midi files on an sd card.

The app is not required if you access the midi files from the sd card. You don't even need to install it.

The app is optional, and its for browsing your library. Think of it like the Photos app but for MIDI.
