Electronic musical apparatus with authorized modification of protected contents
First Claim
1. An electronic musical apparatus designed for using original music contents kept under protection, comprising:
- an editing section operable to edit an original music content into a variational music content;
a content judging section that compares the variational music content with the original music content and judges a degree of difference therebetween to provide a judgment; and
a transfer control section that operates based on the judgment for permitting transfer of the variational music content to an external apparatus beyond the protection.

Abstract
An electronic musical apparatus is designed for using original music contents kept under protection. In the apparatus, an editing section is operable to edit an original music content into a variational music content. A content judging section compares the variational music content with the original music content and judges a degree of difference therebetween to provide a judgment. A transfer control section operates based on the judgment for permitting transfer of the variational music content to an external apparatus beyond the protection. The content judging section operates when a degree of difference is sufficient to remove the protection for providing a positive judgment and operates when a degree of difference is insufficient to remove the protection for providing a negative judgment, and responds to the positive judgment for permitting transfer of the variational music content beyond the protection and responds to the negative judgment for inhibiting transfer of the variational music content within the protection.

8. A program for use in an electronic musical apparatus having a CPU and being designed for using original music contents kept under protection, the program being executable by the CPU for causing the electronic musical apparatus to perform a process comprising the steps of:
-
editing an original music content into a variational music content;
comparing the variational music content with the original music content and judging a degree of difference therebetween to provide a judgment; and
permitting transfer of the variational music content to an external apparatus beyond the protection according to the judgment.
