- **BREAKING!** Changed `param.pitch` to represent semitones, i.e. `note.pitch = -12` will reduce pitch by one octave, setting the playback rate to `0.5` [#45](https://github.com/adamrenklint/bap/issues/45) [(Manvir Singh)](https://github.com/gurs1kh)
- Added `bap.pitchByRatio` helper to calculate exact pitch [(Manvir Singh)](https://github.com/gurs1kh)

- Added `pitch` and `pan` attributes on Pattern, which will affect all of its channels and notes
- Fixed an issue where if a layer was used in multiple slots, the wrong slot would be used to calculate composite params [#46](https://github.com/adamrenklint/bap/issues/46)
## v0.5.1 (2016-05-19) [diff](https://github.com/adamrenklint/bap/compare/v0.5.0...v0.5.1)
