- Battery Care: For best battery life, avoid fully discharging the battery frequently. Charge the device regularly, even if not in constant use.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not pairing (light flashing) | MIDI A adapter is not powered on, or MIDI B adapter is not connected/recognized. | Ensure the MIDI A adapter's switch is "ON". Verify MIDI B is securely connected to a powered USB port. Try restarting both devices. |
| No MIDI signal | Incorrect connection, software not configured, or device not powered. | Check that MIDI A's OUT is connected to the instrument's OUT, and MIDI A's IN to the instrument's IN. Confirm successful pairing (solid light). Ensure your computer's MIDI software recognizes the MIDI B adapter. |
| Short battery life | Battery not fully charged or aging battery. | Charge the MIDI A adapter fully before use. If battery life significantly degrades over time, contact support. |
| Intermittent connection | Interference from other 2.4GHz devices or distance too great. | Reduce distance between MIDI A and MIDI B. Minimize other 2.4GHz wireless activity in the area. |
