        MidiHandler

Class to encapsulate all the midi processing needed for getting input to a Raphsto model. Read in midi files using the midi library and load an midi.EventStream. Then use this class to get whatever form of data out of it you need for your input.

init(self, stream, time_unit=4, remove_drums=False, tick_offset=0)
(Constructor)

source code

x.__init__(...) initializes x; see help(type(x)) for signature

Parameters:

stream (midi.EventStream) - the midi data to get input from
time_unit (int or float) - number of beats to take as the basic unit of time for observations

Overrides: object.__init__

get_emission_stream(self)

source code

Get a list of emissions from the midi stream's note on events.

Returns a 2-tuple of the list of emissions and their corresponding start times in midi ticks.

get_slices(self)

source code

Get a list of midi.slice.EventStreamSlices corresponding to the chunks that this midi stream will be divided into. This includes all midi events, not just note-ons.
