License clarification needed for Yamaha CP80 Electric Grand Piano and Shanai

[hcsrtg]

In Discord GM, the electric piano appears to have a different license (CC0 instead of CC-BY) to the original source, was the license updated by Greg? And The shanai appears to only have "CC" as a license, it doesn't specify what Creative Commons license it uses.

Kinwie got permission from Greg Sullivan, for this specific project.
No idea about shanai; we'd have to ask the contributor.

If anyone gets serious about this GM bank and its rights, we need to ask Kinwie for help documenting these things.

Kinwie and I published GregSullivan.E-Pianos

was the license updated by Greg?

Good question, it was some years ago, I should check some backup for his emails about permissions to see if we can change CC-BY to more permissive, the original work didn't had any because he gave for grant that once published was free for use, but I'm not sure if he really asked for attribution, he gave us "carte blanche" and I thought CC-BY-3.0 doesn't have any issue with instruments.

About "Shanai" I have no idea where it comes from but it's clearly a typo. @kinwie: thoughts?

The correct name is Shehnai.

For Shanai, It has "CC)" which is a typo, was supposed to be "CC0".

And while the correct spelling seems to be "shehnai", "shanai" is how it's spelled in the GM spec.
