Advantages of Bluetooth MIDI Over USB

Feature	Bluetooth MIDI	USB MIDI
Portability	Wireless, fewer cables	Requires cable connection
Latency	Slightly higher (10–20ms)	Lower, more stable
Power	Runs on keyboard battery	Powered by USB
Multi-device	Can pair with multiple devices	Single connection only

Recommendation: For home practice, Bluetooth MIDI is often sufficient. For studio recording, USB may offer slightly more reliable performance.

Apps to Maximize Your Practice Experience

• GarageBand: Record and layer multiple tracks
• Flowkey: Interactive lessons with guided play
• FL Studio Mobile: Advanced sequencing and synth integration

Tip: Pair your Smart Keyboard with these apps for a full-featured learning experience.

Caring for Your Smart Keyboard

• Keep firmware updated: Improves Bluetooth stability
• Avoid interference: Keep away from Wi-Fi routers or microwaves
• Charge regularly: Bluetooth MIDI uses keyboard battery
• Clean keys gently with microfiber to prevent dirt buildup

Optimizing Latency for Bluetooth MIDI Connections

While Bluetooth MIDI is convenient, some users notice a slight delay between key presses and sound output. To minimize latency:

• Keep your device close to the keyboard to maintain a strong signal.
• Close background apps on your Android/iPhone to free up processing power.
• Update firmware on your smart keyboard regularly.
• Use low-latency apps designed for real-time piano practice, like Simply Piano Android or GarageBand.

Tip: A small latency of 10–20ms is normal and usually unnoticeable for beginners.

Connecting Your Keyboard to Multiple Devices

Bluetooth MIDI allows you to connect your smart keyboard to multiple devices, such as:

• Tablet for lessons
• Phone for recording
• Laptop for MIDI sequencing

Steps:

1. Pair your keyboard with the first device.
2. Enable Bluetooth MIDI on the second device.
3. Some apps may require disconnecting the first device before pairing the second.

Tip: Use one device for learning and another for recording to optimize performance.

Using MIDI Foot Controllers with Your Smart Keyboard

MIDI foot controllers can expand your practice and performance experience:

• Control sustain, pitch, or program changes without using your hands.
• Pair via Bluetooth if supported, or connect via USB.
• Ideal for live performances and hands-free control during practice.

Example: Pair a MIDI foot controller with your Smart Keyboard to control sustain pedals in apps like GarageBand or Simply Piano Android.

Advanced App Integrations for Android and iOS

Once connected, your smart keyboard can unlock advanced features:

• Layer sounds: Combine piano with strings or synth patches.
• Recording: Capture lessons or practice sessions in high-quality MIDI format.
• Interactive lessons: Apps like Simply Piano highlight notes in real-time, showing progress and feedback.
  

Tip: Check app settings to ensure MIDI input is active and the keyboard is recognized as a MIDI input device.

Troubleshooting Common Bluetooth MIDI Issues

Even with modern devices, you may encounter connection problems. Common issues and solutions:

• Keyboard not appearing in device list: Restart both devices and enable Bluetooth MIDI on the keyboard.
• Dropouts or stuttering: Reduce distance between devices and remove obstacles.
• Multiple devices not connecting: Disconnect one device before connecting another.
