MPELACE
A hex isomorphic keyboard — any chord shape is rigid and slides anywhere. Tuned to exact 5-limit just intonation (toggle 31-EDO), it plays its own Web Audio synth AND routes out via true per-note MPE MIDI to your DAW or hardware, in exact microtonal tuning.

Tap/click hexes to play (multi-touch chords work). Keys 1234567 / qwertyu / asdfghj / zxcvbnm play four lattice rows. t toggles JI ↔ 31-EDO. Neighbours are consonant: right = fifth (3/2), up-right = major third (5/4). Violet marks the tonic and every held note; held cells shimmer at |exact − 12-TET| Hz — still if near-tempered, gently beating if a pure third or seventh.
