Using a third-party programmable remote

A third-party programmable remote can be used with the miniDSP Flex. See this page on our support site for the codes to use:

Programming a Logitech Harmony remote

The miniDSP Flex can be used with a Logitech®️ Harmony®️ remote. The same functions as the stock remote are programmed into the Harmony database. In addition, you can set up buttons for direct input source selection (instead of cycling through input sources).

The procedure is as described in the application note linked below, except that you should select "minidsp flex" as the device instead of "shd".

If you're keen to just get started, here are the direct links to the app:

Note that currently the miniDSP Control App cannot be used over the Bluetooth connection. It will work only if a Wi-DG is connected to the USB port of the Flex.


If the USB port is being used for iOS/Android app control via the Wi-DG, it cannot be used for USB Audio streaming.
