dari script game berikut tambahkan fitur agar dapat membuatkan music dari pola future bounce yang di buat, jadi misal nya pola nya di buat menggunakan Z    #####     #####
Z       #         #
Z      #         #
Z     #         #
Z    #####     #####

I    #####
I      #
I      #
I      #
I    #####,,, yang dimana ini huruf Z Z I , jadi script akan membuatkan pola future bounce ini pada game sebelum future bounce dari file midi nya di mulai, dan bounce peg nya akan membentuk huruf yang di input ini seperti Z Z I, 1 symbol # berarti 2 note yang dimana square akan bouce sehingga membantuk huruf yang di input pada game sebelum melanjutkan ke bounce dari file midi, jadi suara music future bounce yang dibuat ini gunakan pretty midi untuk men generate suara music nya, buatkan dengan lengkap dan benar : import pygame
