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.
How does it work?
It is super simple.
Use the MIDI IN menu to select a source to listen for MIDI notes.
Use the MIDI OUT menu to send the MIDI output to somewhere (i.e. sequencer, keyboard, etc)
Select a Musical Key (Scale) to restrict the MIDI output to
Select an action to perform when Always In Keys receives a note that is outside the selected key.
