My main interests in xenharmonics are the more unusual equal divisions and harmonic series with sub-octave repetition.
While mostly a mathematical and listener's interest, I've made an a few plugins for musescore and a few compositions.
My plugins can be found listed on the MuseScore page.
I have named the modes of smitonic, the uranian scale and its modes, and have developed a consistent system for naming notes on scales with 10 and 11 naturals:
10 notes: Greek numerals - Α-Β-Γ-Δ-Ε-Ϛ/Ϝ-Ζ-Η-Θ-Ι
11notes: Cyrillic numerals + Ѧ (standing for ІА = 11) - А-В-Г-Д-Е-Ѕ-З-И-Ѳ-І-Ѧ
