     <p>A chord and progression machine. The whole idea fits in one sentence: <strong>you don't play the notes of a chord, you describe it</strong> — a root, a type, some tensions — and the machine takes it from there, all the way to your synths or your DAW.</p>

     <p>The <code>6</code> <code>m7</code> <code>M7</code> <code>9</code> <code>11</code> <code>13</code> tensions stay active and are harmonised <strong>within the scale</strong>: the 7th on G in C major gives a real G7 (with a natural F). The asterisk in the name (<code>G7*</code>) marks that diatonic harmonisation.</p>
     <div class="tip"><strong>Harmonic minor</strong> is worth a try: its V degree becomes a genuine dominant chord with a leading tone — the classic minor cadence, with one finger.</div>
+    <p><strong>Type and tensions.</strong> By default the quality comes from the degree (auto mode). You can <strong>pin</strong> a type button to force a quality on the played root, then click again to return to auto; the root always stays in key. All twelve tensions and alterations (including ♭9, ♯9, ♯11, ♭5, ♯5) work in both cases.</p>
