            Zieh deine Maus durch den Pad und verwandle Bewegungen in Klang. Drei LFOs,
            FM-Experimente und ein Delay/Distortion-Hybrid werden live verschaltet.
-            Die Bitcoin-Feeds von Coindesk (<strong><?= htmlspecialchars($btcLabel) ?></strong>)
-            und CoinMarketCap (<strong><?= htmlspecialchars($btcCmcLabel) ?></strong>)
-            mischen das Routing zusätzlich – sogar die Uhrzeit entscheidet, welches Instrument
-            sich meldet und wie die Resonanzen pulsieren.
+            Der aktuelle Bitcoin-Kurs (<strong><?= htmlspecialchars($btcLabel) ?></strong>)
+            steuert, wie aggressiv der Mix moduliert und rückgekoppelt wird.
