jazzparser.misc.raphsto.midi.ChordSequenceRealizer

Class ChordSequenceRealizer

object --+ | ChordSequenceRealizer

Factory to take the output from the labeller and realize the chord sequence as a midi file.

Very basic - not going to sound great, but it's easier than playing it myself.

Instance Methods

__init__(self, labels, resolution=120, chord_length=2, times=None, text_events=False, state_formatter=None)
x.__init__(...) initializes x; see help(type(x)) for signature

source code

generate(self, overlay=None, offset=0)
Generates a midi stream.

Parameters:

labels (list of tuples) - state label tuples output by the model
resolution (int) - midi resolution to give the result (midi ticks per beat)
chord_length (int) - length of each chord as a number of beats
times (list of ints) - optional onset time for each chord in midi ticks. If not given, it will be calculated by giving chord_length to every chord
text_events (bool) - include chord labels in the midi as text events
state_formatter (1-arg function) - function to take a state label and produce the text label that will go in the midi data. Optional: by default, will use jazzparser.misc.raphsto.format_state_as_chord.
