Applies to Launchkey 25, 37, 49 and 61 MK3
When enabled, Scale mode forces the keyboard notes played to be corrected to a specific scale.
Pressing Scale will turn this on. The scale is selected by holding Shift and then pressing Scale. The bottom row of pads will light up purple, this is used to select the Mode of the Scale.
The Root note of the scale is selected by pressing the note on the keyboard. The selected scale and root note will be displayed on the screen.
When an out of scale note is pressed it is then shifted as detailed below. The number represents the shift in semitones. Note that major/minor intervals are inverted rather than pitching in one direction, which is important for the chord mode.
|0: Root||1: Minor 2nd||2: Major 2nd||3: Minor 3rd||4: Major 3rd||5: Perfect 4th|
|6: Diminished 5th||7: Perfect 5th||8: Minor 6th||9: Major 6th||10: Minor 7th||11: Major 7th||12: Octave|
So, for example, if the note C sharp (C#) was played when the C Major scale was used then a D would play, as this is C# shifted by one semitone.
If 2 notes are played on the keyboard that trigger the same note (after the values are changed to match the selected scale) a second note on message is sent but no note off is sent for the first note played. The second played note will trigger the note off.
