iOS does not have a built-in tool that displays connected device. We recommend installing a MIDI monitor app such as [MIDI Wrench](https://apps.apple.com/us/app/midi-wrench/id589243566).
When you connect an external device, the system will inform you with a notification. Tap the notification and make sure that **MIDI** is selected. ![](android.png =300x*)
## Troubleshooting If your instrument is not correctly recognized try to perform one or more of these operations: - Use a different USB port. - Use a different USB cable. - If you have a laptop, connect it to the power supply. - As a temporary test, disconnect any other USB device to avoid interferences. - [Restore the MIDI devices](/support/articles/1850987/).
