There are many conceivable ways to map 19edo onto the onto the Lumatone keyboard. Only one, however, agrees with the Standard Lumatone mapping for Pythagorean. This is "Preset 4 — 19-ET Bosanquet" in the official manual.

are good options if you want to extend your range while making well-tuned chords easy to play. The Hanson mapping works especially well since 19edo can be conceptualised as a chain of essentially pure 6/5s.
The Lumatone mapping for sensi is also another option, putting the notes of minor and major chords extremely close to each other:

The Magic mapping has an even wider range and makes 5-limit chords just as easy to play, but the 3L 4s MOS scale is somewhat lopsided with its 5:1 step ratio, the chroma goes downwards in the most efficient layout, and higher limit intervals require more awkward finger stretches.
