<aside> ⚠️ The controls in the MIDI section are not programmable per patch.

When on, all notes input into OB-X via an external controller, or GUI keyboard will be held down indefinitely until disabled. This button is hardwired to be controlled by CC64 (sustain pedal).
Even in monophonic modes, hold will allow you to hold any number of keys.
Press and hold a chord on the keyboard, or use Hold to input one a note at a time, then activate the chord switch to store that chord.
To overwrite the current chord, press again to deactivate and repeat the step above. Or Ctrl (PC) or Cmd (Mac) clicking will erase the chord.
<aside> ⚠️ The first key you press when inputting a chord is assumed to be the root of the chord. When chord mode is active the new chords will calculate from this root.
For instance, if you play a C chord with your right hand and ensure that the C is the first of those keys played, you can then add a lower C below the chord and the transposition will happen from the first, upper, C.
</aside>
This changes the chord mode’s behaviour. There are two modes:
Classic Mode - mimics the hardware - The first note pressed plays a chord, and any additional notes played on top will use spare voices to play as normal
Stacked Mode - plays a chord for every note pressed.
<aside> 💡 Combining stacked chords, key mode and arpeggiator can create really powerfully complex arpeggiations.

This applies and works in conjunction with Chord mode. The Key screen enables the selection of a root note and a scale (Major, Harmonic, Melodic, Natural) to which the chord mode will conform. Click and drag to quickly change key or right-click to navigate the menu.
Each key-transposed note is calculated independently of one another. So if you request a chord that is out of the selected key each note will either move, or not move, depending on if it is in key. This can create some wonderful variations to chords when playing a root note 1 semitone out of key. Note also that the key you are playing can also be transposed so you will not necessarily hear the note you’re holding.
<aside> ⚠️ Example If you store a C chord (C, E and G) and set Cmaj as the key. But then proceed to play a C# root (normally C#, F G#) the resulting chord will be a Csus4 (C, F, G) as only the F will be untransposed by key mode.
