If you find (transcription) errors in a publication by another music supplier, we would be grateful if you could make the necessary improvements yourself and provide the corresponding files. You can also add voice extractions. We have built in a procedure to make it easy for you to send us those files. As a reward, you will receive a free extension of your membership.
