Changing Music Inside will not affect this Waveview. you must convert your own music to RAW then, convert HEX codes to HEX strings, Import here, see BG script, click that engine to apply, one thing,. u must set samplerate of ur own music to 1000 at least in case can't be uploaded, otherwise, change script on sprite "timer * (samplerate)"
WAV > RAW 8-BIT PCM > HEX > Import to WAV List on Scratch Maybe Right
