Sing and Sign hardware proof layer

Studio hardware that signs every take, so origin is provable from the moment it is recorded.

Two instruments. Each one captures the take and signs it at the source, so a vocal or a riff carries proof of origin, performer, and device before it ever reaches a vault, a label, or a release.
