- minDur :: Time
- getVoices :: [Voice]
- data Key
- data TimeSig
- type Voice = [Timed ScoreEvent]

Score representation of a MidiFile
Stores the main elements of a musical score that can be derived from a midifile
Constructors
| MidiScore | |
Fields
| |
Represents a musical key
type Voice = [Timed ScoreEvent] Source
A Voice is a list of ScoreEvents that have time stamps.
The MIDI Channel as stored in the MIDI file
Pitch is represented by a PitchClass and an Octave
Constructors
| Pitch (Octave, PitchClass) |
Represents a musical octave
newtype PitchClass Source
A Pitch class representation (there is no check for values > 11)
Constructors
| PitchClass | |
Fields
| |
Represents a musical interval
Represents MIDI velocity
Adds MIDI Time information to a datatype
Represents MIDI time in ticks
A Bar counter used to interpret a MIDI Time stamp
A counter for musical beats
data ScoreEvent Source
Within ZMidi.Score we represent four score events: a note, a key change, a time signature or a tempo change
