The two different issues of the 1501 edition (vdm 736 and vdm 362) are very similar. Only a close comparison reveals minor differences in the title page and colophon, such as the spelling of Quentel/ Quentell in the colophon, and some differences in the line breaks.
Melchior Schanppecher is the author of the last two parts of the book, the Musica figurativa.

A1v: Epigramma Ad lectorem (Musica dulce sonans...).
