#### Custom sysex request

This option allows to send a custom system exclusive message to the synthesizer in order to start the backup from the browser. In this case you need to know which message to send to initiate the backup. To start the backup from the browser:

1. Type the system exclusive message in the **Custom sysex request** field (refer to synth manual to know if this is supported)
2. Click **Send button** [![image.png](https://wiki.synthsonline.com/uploads/images/gallery/2023-01/scaled-1680-/t0Wimage.png)](https://wiki.synthsonline.com/uploads/images/gallery/2023-01/t0Wimage.png)

If you sent the correct command to the synthesizer and it support its, messages will start to be transfered in the same way as the standard manual dump.
