Python 如何使pygame的midi同时播放音符

我正在try 创建一个应用程序，它将帮助训练人的耳朵听到不同的音调.我目前正在研究一个按钮数组，它将具有从八度3到5的每个色调音符.当这些按钮中的一个被按下时，它将执行上面用Electron 游戏包编写的功能.

我遇到的问题是，一旦按钮被按下，整个应用程序似乎都在等待，直到播放完该音符(只有1秒).这些按钮将注册输入，然后播放它们，只是不是同时播放.我希望能够在任何时候点击任何音符并让它被播放.

import pygame
import time
import pygame.midi

# mixer config
# freq = 44100  # audio CD quality
# bitsize = -16   # unsigned 16 bit
# channels = 2  # 1 is mono, 2 is stereo
# buffer = 1024   # number of samples
# pygame.mixer.init(freq, bitsize, channels, buffer)
# pygame.mixer.music.set_volume(0.8)

pygame.midi.init()
fps = 60
timer = pygame.time.Clock()
player= pygame.midi.Output(0)
player.set_instrument(1,1) #127 is max

major=[0,4,7,12]

def go(note):
    player.note_on(note, 127,1)
    time.sleep(1)
    player.note_off(note,127,1)

我正在使用pyqt5编写应用程序，相关的按钮代码如下.我不确定问题是与按钮如何执行功能有关，还是与pyGame MIDI功能有关.
