Hi,
I have some live solo piano recordings of classical music I recorded years ago. There is no midi file as these are live recordings, and these were recorded using and tape recorder and single microphone, so what should I do about the Original Certificate?
The tape recorder isn’t the specialized recording equipment, I’m afraid that the recorded work cannot conform to general commercial quality standards, but you can try to upload it and wait for the review by relevant staff. The original certification of solo music needs the midi file (you can just provide a part of the music work) or the audio version without mixing.
