Thank you for so much advice
for three months, I have been working with musescore intensively as I was not able to do my actual job. I am going to start with it next Monday for four days and on Friday, I will decide how to continue.
It was a pleasure to read your threads. If I keep working on my old job, I will tell you. You have helped me a lot. Tomorrow, I am going to upload a composition that is not written by me and it is vocal and in German.
