mutwo.converters.frontends.midi_constants module

Several constants which are used for the midi converter module.

There are basically two types of constants:

1. Default values for mutwo.converters.frontends.MidiFileConverter constructor.

2. Values that are defined by the midi file standard.

Data:

ALLOWED_MIDI_CHANNELS	midi channels that are allowed (following the standard midi file definition).
DEFAULT_AVAILABLE_MIDI_CHANNELS	default value for available_midi_channels in MidiFileConverter
DEFAULT_MAXIMUM_PITCH_BEND_DEVIATION_IN_CENTS	default value for maximum_pitch_bend_deviation_in_cents in MidiFileConverter
DEFAULT_MIDI_FILE_TYPE	default value for midi_file_type in MidiFileConverter
DEFAULT_MIDI_INSTRUMENT_NAME	default value for midi_instrument_name in MidiFileConverter
DEFAULT_N_MIDI_CHANNELS_PER_TRACK	default value for n_midi_channels_per_track in MidiFileConverter
DEFAULT_TICKS_PER_BEAT	default value for ticks_per_beat in MidiFileConverter
MAXIMUM_PITCH_BEND	the highest allowed value for midi pitch bend
MIDI_TEMPO_FACTOR	factor to multiply beats-in-seconds to get beats-in-microseconds (which is the tempo unit for midi)
NEUTRAL_PITCH_BEND	the value for midi pitch bend when the resulting pitch doesn't change

ALLOWED_MIDI_CHANNELS = (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)
