Source Code Overview

A brief description of the source code is given here.

ChooseSongActivity.java The ativity used to display a list of songs to choose from. The list is created from the songs shipped with MidiSheetMusic (in the assets directory), and also by searching for midi files in the internal/external device storage. When a song is chosen, this calls the SheetMusicActivity, passing the raw midi byte[] data as a parameter in the Intent.
SheetMusicActivity.java The main activity that contains the MidiPlayer, Piano, and SheetMusic.
SettingsActivity.java The activity created by the "Settings" menu. This is used to modify various sheet music and playback settings (which tracks to display, which instruments to use, and so forth). After pressing the back button, the settings are stored in a MidiOptions object, and are passed back to the SheetMusicActivity.
MidiFile.java This class is used to read in and parse a MIDI file. The constructor takes a filename as argument, and returns a MidiFile class containing the following:
  • The MIDI tracks (List<MidiTrack>)
  • The MIDI time signature (TimeSignature)
  • The MIDI events per track (MidiEvent)
  • The instrument per track (MidiTrack.Instrument)
  • The notes per track (List<MidiNote>)
  • For each note, the note number, start pulse time, and duration (MidiNote).
The MidiFile class has two methods for applying the menu options to the MIDI song:
  • ChangeMidiNotes modifies the parsed MidiNote data.
  • ChangeSound creates a new MIDI music file for playback, with the new instruments, speed, transpose, etc.
SheetMusic.java This is a graphical Control that displays the actual sheet music. It takes a parsed MidiFile as argument, as well as the MidiOptions specified by the menu items. The class also supports highlighting notes during playback (ShadeNotes).
MidiPlayer.java This is the toolbar at the top containing the controls (play, stop, speed, volume) for playing the music. It uses the MidiFile.ChangeSound() method to modify the sound settings, and create a new MIDI music file for playback.
Piano.java The Piano is used to display the notes being played as the MIDI music is being played. The method ShadeNotes is used to highlight the appropriate notes.
Staff.java The SheetMusic displayed consists of a list of Staffs. Each Staff instance corresponds to one horizontal staff. Each Staff contains a list of MusicSymbols to draw (clefs, notes, accidentals, rests, bars, etc). The actual Music Symbols are described in the diagram below.
ChordSymbol.java The main music symbol is the ChordSymbol, which represents a group of notes that are played at the same time. Chords are the most complicated symbols to draw because of the many variations in note placement, stem placement, etc. The Music Symbol Diagram below illustrates several types of chord symbols:
  • Chords with one note (#6, #7, #8).
  • Chords with multiple notes (#9, #11).
  • Chords with one stem (#6, #7, #8).
  • Chords with two stems in different directions (#9, #11)
  • Notes with different durations (#11).
  • Notes with accidental (sharp/flat/natural) symbols (#11).
  • Notes that vertically overlap (#11).
  • Stems positioned on the left side of notes (#9).
  • Stems positioned on the right side of notes (#6).
  • Stems that connect two chords together (#7, #8).
  • Stems that are only part of one chord (#6).
