Default Key signature finder?

Is there a script that will listen to the notes I play on my midi keyboard and show all key signatures/scales that match the notes that I'm currently holding down?

When I'm figuring out a song (edit: or writing), I often have like 4 notes and I want to be shown a list of options of what keys I could be in.

Just as an example, if I hold down C D G A, the script would display:

C major
G major
F major

etc.

You can use the Scale Finder and check "use all MIDI inputs".

Oh, handy! Thanks!

For anyone who doesn't know, just go to View > Scale Finder.

It's easy to figure out what key a song is in. It's almost always the chord that the song ends in. Specifically, the tonic note, or base note, of the chord. EX: A C Major chord is C-E-G. C is the base or tonic. If that chord ends the song, and is what the harmony keeps returning to, it's in the key of C. Usually Major. If it sounds sad, it's C minor.

Occasionally a song will end in a different key, especially in progressive stuff. Then you have to assume it's in the key that the song is in most of the way through. Usually in a case like that, the last chord will be a sudden modulation to a new key. But you would still keep it in the predominant key. Unless the ending goes on for a long time. Like in "The Look Of Love" by Herb Alpert & The Tijuana Brass. That ending is a modulation that goes on for awhile. You might change the key sig at that point if it makes sense (minimized the use of sharps and flats).

Songs usually also start in the same key they end in.
