Microtonal
Play in any TUNING. A SCALE node sets the master tonality — here Hindustani raga Yaman in just intonation with the tanpura DRONE on — and the Keyboard follows it, so every key plays a pure microtonal interval (the natural notes between the piano keys). Press a key and hear it lock against the drone. On the Scale node, pick a different system (Just Intonation, a Turkish makam, an Arabic maqam, gamelan, an EDO, the non-octave Bohlen-Pierce), move the tonic, or toggle the drone — the whole patch retunes. The Keyboard's Tuning can be set to 'Follow' (default) or '12-TET' to opt out. A FUNCTIONAL preset (explicit nodes + connections).
