quantizationtools.millisecond_pitch_pairs_to_q_events

abjad.tools.quantizationtools.millisecond_pitch_pairs_to_q_events.millisecond_pitch_pairs_to_q_events(pairs)

Convert a list of pairs of millisecond durations and pitches to a list of QEvent instances.

Pitch values must be one of the following:

1. A single chromatic pitch number, indicating a note,
2. None, indicating a silence, or
3. An iterable of chromatic pitch numbers, indicating a chord.
