Always In Key is a small utility app that allows a user to select a musical key and restrict the MIDI output to only notes contained in that key.
Well, for any number of reasons really. Let's say that you are ad-libbing a lead on your synth (and you know the key in which you are playing), you can simply route your MIDI into this app and jam away without fear of playing any wrong notes.
