Thank you for your reply. I have two more questions
Can I set the key?
As for the text, I would like to know if there is a general list of instruments, because I find that some instruments are not very good. Do you have any good suggestions on the writing of text content? There are some texts that I get musical representation that is not very good.
Thank you again for your patient reply and best wishes
When you specify a chord in your code, what does the key look like? Is it the default C major?
