MIDI Signet
Generate an author key, then stamp a tamper-evident signature straight into a MIDI file's own track data. Everything happens on this device — no file ever leaves it.
Step 01
Author identity
Anything you want bound to the signature: publisher, ISWC, license, contact.
Step 02
Sign a MIDI file
The signature is written into a dedicated MIDI track, so the signed file still plays anywhere.
Signatures prove which key signed a file. Share your fingerprint publicly so listeners can match it.
