Method Details [hide private]

__str__(self)
(Informal representation operator)

source code 

str(x)

Overrides: object.__str__
(inherited documentation)

decode_data(self)

source code 

Takes the data that's been read into data instance variable and sets instance attributes from the values in it. What this does is specific to the event type.

At the simplest, it could do nothing, just leaving the raw data in data, but more likely it will decode values from the data.

Overrides: Event.decode_data
(inherited documentation)

encode_data(self)

source code 

Produces byte data to represent this event on the basis of instance variables. This is the data that will be written to a MIDI stream (not including the tick and status message).

Returns:
byte data as a string
Overrides: Event.encode_data
(inherited documentation)

Class Variable Details [hide private]

accidentals

Number of sharps/flats. Positive sharps, negative flats.

Value:
