Velocity 0 is generally assumed to be the same as a note-off message. The attribute stores an integer representation (0-127). The velocity attribute is only defined for note-on and note-off messages. The attribute stores an integer representation (0-127, with 60 = middle C). The pitch attribute is only defined for note-on and note-off messages. This value is not essential, as ultimate time positioning is The time attribute is an integer duration of the event in ticks. The channel attribute is an integer channel id, from 1 to 16. The type attribute is an enumeration of a Midi event from the ChannelVoiceMessages Objects in the list of events in a MidiTrack object. MidiEvent objects are paired (preceded) by DeltaTime MidiEvent ( track : Optional = None, type = None, time : int = 0, channel : Optional = None ) ¶Ī model of a MIDI event, including note-on, note-off, program change, The channel attribute, inherited from MidiEvent is not used and set to None Time values are in integers, representing ticks. The track argument must be a MidiTrack object. Pairs of DeltaTime and MidiEvent objects are the basic presentation of temporal data. Time change (in ticks) since the start or since the last MidiEvent. DeltaTime ( track, time = 0, channel = None ) ¶ ChannelVoiceMessages ( value ) ¶ĭeltaTime ¶ class music21.midi.
