        Modes
        
        These are different starting positions for major scales
        
        So will have to handle these
        
        Types:
        
        Ionian
        
        Dorian

        Aeolian
        
        Locrian
        
        Work out notes to play
        
        Need to convert from note no. to note name, or perhaps notes within a key?

        Vector storing note names (index as key number)
    - - Choose direction / destination :check:
      - Press
        
        signal to press same key as user +- x octaves :check:
      - Release
        
        Signal to release same key as user +- x octaves :check:
  - - - Separate MIDI channel
      - Read stop positions
  - - - Hold preset button for x seconds to record:question:
      - Separate button to save current positions? :question:
      - Move stops manually
        
        Receive stop positions and save
    - - Change MIDI output instrument
      - Send signal to Move the stops
      - Held or toggled?
        
        A setting?
- - - - Handling MIDI instruments :check:
        
        MIDI not arranged for this machine
        
        Choose which track(s) to output :check:
        
        Handling the same key pressed by different channels :!?:
        
        Default instrument :check:
        
        MIDI arranged for this machine
        
        Using the different instruments as presets for all possible stop positions :check:
        
        Option to enable this mode? :!?:
      - Handle notes outside range
        
        Shift octave if possible?
        
        Ignore them
      - Release key filtering :check:
        
        Only release keys not pressed by plugins :check:
        
        Send signals to press/release keys
        
        link to check:
  - - - Sort into keypresses by the system and by the user :check:
        
        System keypresses :check:
        
        Ignore system keypresses for internal functions :check:
        
        Choose whether to output to MIDI :
        
        Possibly split to alternate channel :question:
        
        User keypresses :check:
        
        Array or vector storing state :check:
        
        3 states: off/userOn/systemOn :green_cross:
        
        Or 2 variables per key: state (on/off) and operator (system/specific plugin or user) :green_cross:
        
        management for when multiple sources use the same key :check:
        
        separate array/vector acting as buffer for each key :check:
        
        Each module (each MIDI input or plugin) that asks for the key to be pressed adds to the buffer when it wants note on, removes when it wants note off :check:
        
        So long as buffer >=1 key stays pressed :check:
      - Ignore very short presses? :question: :!?:
  - - - Convert to MIDI format
        
        Output MIDI :
      - Separate channels? :green_cross:
      - Single channel using an instrument representing the current stop arrangement? :check:
  - - - Constantly checking schedule
