+
+## Verwendung
+
+### Grundlegende Konfiguration
+
+`include/FIRMWARE_DEF.h`:
+
+```cpp
+#define N_KEYBOARD_ROW  4      // Keyboard Reihen
+#define N_KEYBOARD_COL  3      // Keyboard Spalten
+#define N_CV_GATES      2      // CV-Ausgänge
+#define N_SB            2      // Sequencer
+
+// I2C Pins
+#define PIN_SDA         15

+// Keyboard Pins (Reihen)

+#define PIN_K_C1        2
+#define PIN_K_C2        4
+```
+
+### Spannung-Mapping
+
+`src/main.cpp`:
+
+```cpp
+// Voltage für jede Tastaturposition (in 1/12V = 83mV Schritten = 1 Halbtonschritt)
+uint16_t keyToVoltage[N_KEYBOARD_ROW*N_KEYBOARD_COL] = {
+    1*83, 5*83, 9*83,    // Row 0: C, E, G
+    2*83, 6*83, 10*83,   // Row 1: D, F, A
+    3*83, 7*83, 11*83,   // Row 2: E, G, B
+    4*83, 8*83, 12*83    // Row 3: F, A, C (Oktave)

+2. Sequencer 2 Playing?

+   └─ NEIN ↓
+
+3. Live Input
+   └─ Gebe Tasten-Voltages aus (Standard)
+```
+
+Dies ermöglicht nahtlose Übergänge und verhindert Konflikte.

+
+## Code-Beispiele
+
+### Beispiel 1: Live-Modus (main.cpp.1)
+
+Direkte Tastatur-zu-CV Verbindung ohne Sequencer:
+
+```cpp
+void loop() {
+  keyboard.update();
+  
+  int n = keyboard.getQueueLength();
+  
+  if(n > 0) {
+    for(int i = 0; (i < N_CV_GATES) && (i < n); i++) {
+      Key k = keyboard.getQueue(i);
+      cv.setVoltage(i, k);  // Taste direkt auf CV ausgeben
+    }
+  } else {
+    cv.clearAll();  // Keine Taste → 0V
+  }
+  
+  delay(50);
+}

+### Beispiel 2: Dual-Channel Sequencer (main.cpp)
+
+Vollständiger Sequencer mit 2 unabhängigen Kanälen:
+
+```cpp
+void loop() {
+  keyboard.update();
+  handleSequencerButtons();
+  
+  sb1.update();
+  sb2.update();
+  
+  // ... Voltage determination ...
+  
+  // Recording
+  if(sb1.isRecording()) {
+    sb1.addStep(voltage_ch1, voltage_ch2);
+  }
+  if(sb2.isRecording()) {
+    sb2.addStep(voltage_ch1, voltage_ch2);
+  }
+  
+  // Output mit Priorität
+  if(sb1.isPlaying()) {
+    cv.setVoltage(0, sb1.getCurrentVoltageCh1());
+    cv.setVoltage(1, sb1.getCurrentVoltageCh2());
+  }
+  else if(sb2.isPlaying()) {
+    cv.setVoltage(0, sb2.getCurrentVoltageCh1());
+    cv.setVoltage(1, sb2.getCurrentVoltageCh2());
+  }
+  else {
+    cv.setVoltage(0, voltage_ch1);
+    cv.setVoltage(1, voltage_ch2);
+  }
+  
+  delay(10);

+### Voltage-Mapping
+
+Verwendet gleichmäßige 83mV Schritte (1/12 Oktave):
+
+```
+Key (1,0) = 1 × 83mV  = 83mV   (C)
+Key (1,1) = 5 × 83mV  = 415mV  (E)
+Key (1,2) = 9 × 83mV  = 747mV  (G)
+... etc
+Key (4,2) = 12 × 83mV = 996mV  (C')
+```
