Pure Chords
ADAPTIVE JUST INTONATION — every chord locks beat-free. A I–V–vi–IV in C plays through a polyphonic synth; a SCALE node has "Adaptive" on, so the kernel retunes each chord to PURE just ratios (the bass anchored to 12-TET, so the progression never drifts — no comma pump). Toggle Adaptive OFF on the Scale card and the same chords return to ordinary 12-TET temperament: the difference is unmistakable — pure intonation has no beating, the chords "lock". A Tonnetz scope shows the harmony as geometry, gliding between chords. Drop it, press play, and toggle Adaptive to hear it. A FUNCTIONAL preset (explicit nodes + connections).
