Ever wondered what the key of a song being played is? Wonder no more! Just use the built-in piano keyboard to play along with a song's melody. As you confirm notes that coincide with what's being played, KeyFinder will narrow down the number of possible keys the song is in.

Several features include:
• monophonic playback (use KeyFinder as a soloing piano!)
• no distortion, clicking
• red LEDs to mark off improbable notes
• toggle between Major and Relative Minor keys
• use Keyfinder while iPod music continues to play
• HIDDEN easter egg! (There's an undocumented feature)

Pretty nice

It would be nice if it showed the relative minor next to the major. Otherwise, it's really helpful.

Great Program!

Once you figure out how to work it, it's sick! AUTOTUNE? you can find the key easy!
