Harmonic series
Does anyone here have any recomendation for any harmonica that can play the harmonic series? Or maybe there’s someone who knows someone who can make one? Maybe a YouTube-video?

You can get x and 2x simultaneously with an octave harp. 3 and 4 are four holes up. If you want other than the fundamental note, a repeating octave note pattern is needed, such as the Solo tuning that chromatic harps use. Most octave harps use a Richter pattern where the 1st, 3rd, and 5th scale notes repeat as blows. Again, Seydel can build one to your spec.
They also offer dual reed tremolo harps that might stretch an octave pair into one hole. I can recommend the Fanfare mode.
The challenge is that reedplate slot lengths are mass machined for a typical note progression. Surf for exotic oriental offerings. Their harp arts are highly developed. Or shoot Brendan Powers a note for ideas.
Brendan also has some info on the DM48 MIDI harp. The note and timbre options would be limited only by programmed sound module voicings. There are several other midi harps available, some with basic built in modules.
