A patch that sounds similar to a Koto, Harp or Guzheng.
The top row is the melody. I have the “Quant” module set to a Japanese minor pentatonic scale. There’s a random vibrato section and a random note volume section to try to give it a more human feeling.

The bottom row is an octave lower and has only three notes (a minor triad). That way there’s not that much dissonance with the melody.

On the far right is a low pass filter that will mellow out the highs and make it sound more like a western harp.

I don’t think this patch will put too many koto players out of work.
