使用 Python 播放 MIDI Note

方法一：使用music21方法二：使用pygame 使用 Python 播放 MIDI Note 方法一：使用music21

import music21 as m21def play_note(pitch="C4", length=2, velocity=127, instrument='Piano'): note_1 = m21.note.Note(pitch, quarterLength=length) note_1.volume.velocity = velocity stream_1 = m21.stream.Stream() if instrument == 'Piano': stream_1.append(m21.instrument.Piano()) # stream_1.insert(0, m21.instrument.Piano()) stream_1.append(note_1) s_player = m21.midi.realtime.StreamPlayer(stream_1) s_player.play()

注意该方法也需要安装pygame

import pygame.midi as pmpm.init() # init midi playerplayer = pm.Output(0)BPM = 120def play_note(pitch=60, length=2, velocity=127, instrument='Piano'): if instrument == 'Piano': player.set_instrument(0) player.note_on(pitch, velocity) time.sleep(length * 60 / BPM) player.note_off(pitch, velocity)del playerpm.quit()
