What kind of app is this? I just needed it for a long time. Unfortunately, I see that so far, no one has managed to use this application properly, including me. There's probably some error in the code since so many people can't use this service. By the way, usually, in such situations, I just download the melody I need on https://y2mate.mymp3.red/. Although I agree that such an application as you described will be simply irreplaceable for those engaged in music. I sometimes write tracks myself, and I lack such a function as don't always understand what kind of instrument is playing in the song
