如何让PyDirectInput同时按下多个按键？——《光·遇》开发问题

我正在为《Sky: Children of the Light》（光·遇）开发自动演奏工具，通过代码模拟按下对应乐器的按键。目前代码只能实现单键依次按下，无法处理需要多键同时按下的场景。以下是我编写的代码和测试用的JSON乐谱：

import json
import sys
import time

import pydirectinput
import pygetwindow as gw

# 查找指定标题的窗口
window = gw.getWindowsWithTitle("Sky")[0]
print(window)

# 获取命令行参数
arguments = sys.argv

# 激活窗口
window.activate()

# 光·遇按键映射
key_mapping = {
  '1Key0': 'y',
  '1Key1': 'u',
  '1Key2': 'i',
  '1Key3': 'o',
  '1Key4': 'p',
  '1Key5': 'h',
  '1Key6': 'j',
  '1Key7': 'k',
  '1Key8': 'l',
  '1Key9': ';',
  '1Key10': 'n',
  '1Key11': 'm',
  '1Key12': ',',
  '1Key13': '.',
  '1Key14': '/'
}

# 演奏音乐
def play_music(json_data):
        song_notes = json_data[0]['songNotes']
        bpm = json_data[0]['bpm']

        # 计算每个节拍的持续时间（秒）
        beat_duration = 60.0 / bpm

        # 开始演奏
        start_time = time.perf_counter()

        for i, note in enumerate(song_notes):
                note_time = note['time']
                note_key = note['key']

                if note_key in key_mapping:
                        pydirectinput.press(key_mapping[note_key])
                else:
                        print("跳过：按键未在映射中找到")

                # 计算从开始演奏到现在的时间
                elapsed_time = time.perf_counter() - start_time

                if i < len(song_notes) - 1:
                        next_note_time = song_notes[i + 1]['time']
                        # 计算演奏下一个音符前需要等待的时间（毫秒转秒）
                        wait_time = (next_note_time - note_time) / 1000  

                        # 调整等待时间以保持节奏
                        remaining_time = max(0, note_time / 1000 + wait_time - elapsed_time)

                        print("note_time:", note_time)
                        print("wait_time:", wait_time)
                        print("elapsed_time:", elapsed_time)
                        print("remaining_time:", remaining_time)

                        time.sleep(remaining_time)

        # 演奏结束后的延迟
        time.sleep(2)  # 小延迟确保最后一个音符完全演奏完毕
        pydirectinput.press('/')

# 检查是否传入了参数
if len(arguments) > 1:
        custom_value = arguments[1]

        try:
                # 读取本地JSON文件
                with open(f'songs/{custom_value}.json', 'r') as file:
                        json_data = json.load(file)

                # 开始演奏
                play_music(json_data)
        except FileNotFoundError:
                print("未找到指定乐谱。")
else:
        print("未指定乐谱。")
