We present the first movement from Mozart's Piano Concerto 20 in D minor. The solo part is played at the Organ. Tuning system is 12 notes from meantone, generated by a 697-cent fifth and octave period, spanning the chain from Eb to G#. This is different from the historical tuning used by Mozart, probably 1/6-comma meantone, instead.

"Lament & Deception", Chacony in 55edo for Two Violins & Cello
This is my Chacony "Lament & Deception" in 55-equal division of the octave (very close to sixth-comma meantone) for two violins and cello. The piece consists in 33 variations on the lament bass, followed by a deceptive cadence. Each section is a diatonic semitone higher than the preceding one, hence we come back to the orginal tonality (C) every 11 steps (since in 55edo 11 diatonic semitones = 1 octave).
