👉 Do notes light up in Piano Marvel?

• YES → Your keyboard is working
  → Go to: Timing / Latency Issues (iPhone & iPad Fix Guide)
• NO → Continue below

🔍 Step 1 — What Are You Using?

This matters more on iOS than anywhere else.

👉 Choose one:

• USB cable (wired connection) → Go to Step 2
• MIDI interface (DIN cables) → Go to Step 2
• Bluetooth MIDI → Go to Step 5
• Not sure → You’re likely using USB → Go to Step 2

🔌 Step 2 — Check Your Physical Connection

For iPad / iPhone (wired)

• Keyboard powered ON
• Cable firmly connected
• Adapter firmly connected to device

⚠️ Critical (very common issue):

Correct adapters/Cables:

• MIDI IN/OUT to USB A / C Cable
  
• Direct USB B to Lightning Cable
  
• Direct USB B to C Cable
  
• USB A to Lightning / C (Data Only)
  
• USB A to Lightning (Includes Headphone & Charging Port)
  
• USB A to C (Includes Headphone & Charging Port)

⚠️ Common mistakes:

• Cheap adapters that only charge
• Loose connections
• Using a USB hub

👉 Test again.

• Working? → Done
• Still not working? → Continue

🔄 Step 3 — Reset the Connection

• Unplug everything
• Close Piano Marvel
• Reopen the app
• Plug everything back in

👉 Test again.

• Working? → Done
• Still not working? → Continue

⚙️ Step 4 — Check Keyboard Settings

Some keyboards will not send data correctly.

Check:

• Keyboard volume is up
• A normal piano sound is selected
• MIDI output is enabled (if applicable)

⚠️ Common issue:

• Keyboard is powered but not sending MIDI data

👉 Test again.

• Working? → Done
• Still not working? → Continue

📶 Step 5 — Bluetooth MIDI Issues

Bluetooth is convenient—but unreliable if not set up correctly.

Check:

• Device is paired correctly
• Keyboard is discoverable
• Bluetooth is enabled

Try:

• Disconnect and reconnect Bluetooth
• Restart Bluetooth on your device

⚠️ Common issues:

• Paired in iOS settings, but not properly connected for MIDI
• Connection drops silently

👉 Test again.

• Working? → Done
• Still not working? → Continue

🧪 Step 6 — Test the Keyboard Outside Piano Marvel

This isolates the issue.

Try:

• Another music app
• A MIDI testing app  (We recommend MIDI Wrench)

Results:

• Works in another app → Issue is app/config → continue
• Does NOT work anywhere → Hardware/cable/adapter issue

🔄 Step 7 — Restart Your Device

• Power off your iPhone/iPad
• Turn it back on
• Open Piano Marvel

👉 Test again

🧩 Step 8 — Reduce Complexity

• Disconnect other MIDI devices
• Use only one keyboard
• Avoid hubs or splitters

👉 Test again
