• Dynamic sizing of the keyboard (configuration stored per device orientation)
• Stack multiple keyboards (top down or bottom up)

=== Possible next features ... or just a bunch of ideas

• [ ] harmonize handling of pianoview parameters in preferences (currently in PianoView and PianoFragment)
• [ ] grey out or hide notes which cannot be played due to missing sound file
• [ ] add some open source synth to tonality in order to play more than audio files
• [ ] improve scale selection with custom dialog and scale grouping
• [ ] add MIDI keyboard support via USB on the go
• [ ] add metronome to piano view
• [ ] automate screenshot generation combined with espresso UI testing

== Development

=== Build instructinos

• checkout tonality
• Ensure the environment variable ANDROID_NDK is set
• Ensure that gradle can call patch and git, i.e. these should be on your PATH
• Prepare dependencies - this will pull git submodules and build native ffmpeg binaries
  • gradle setupTonalityDependencies +
• build tonality:
  • gradle build

=== Interaction with upstream semitone

You will probably need these only as a maintainer of the project.

These commands assume that remotes named semitone-upstream and semitone-as-a-library. have been set up.

pull:: * commit all changes * git subtree pull --prefix semitone semitone-upstream master * convert semitone into an android library by changing semitone/build.gradle - change build gradle plugin to library - comment out application ID

push:: * commit all changes * git subtree push --prefix semitone semitone-fork semitone-as-a-library * add pull request towards semitone project
