I tried the CME WIDI Uhost(*) on the FR1x front grill USB-A connector (which is meant for an USB memory drive) to check whether the FR1x has the "hidden / undocumented" feature and can serve as a USB MIDi host connector. => It can not :-(
Well, at least you don't then block the USB-drive connector which may come in handy if you need more than 8 user programs or prerecorded accompainment. Or if you don't need the drive the connector can perfectly power the Uhost (**) so you don't need an extra USB power bank.
*) The Uhost is able to automatically switch to either "host" or "client" mode depending on the device you plug it into.
**) The Uhost has two USB-C connectors: One to power the device (from any external USB power bank or directly from the FR1x via the drive port) and one for the MIDI. Watch that you buy the correct cables! CME offers a set with two (theoretically) fitting cables but they are not long enough to be used at the same time with the FR1x. Maybe you can find longer cables elsewhere, CME has labeled the cables as "USB-A to USB-C cable 10cm" and "USB- OTG to USB-C cable 10cm").
PS: As I have already written elsewhere the FR1x DIN MIDI Out connector is able to (self-)power the small and lightweight MIDI Bluetooth adapter "Quicco Sound mi.1" (at least version 1, version 2 I didn't test yet) which may be an alternative to using the Uhost. But you would only have MIDI out then, the FR1x does not allow MIDI in at the DIN plug.
PS 2: To anyone in the future who stumbles across this thread: This topic was already explained by
@Keymn and others. There is a nice photo as well...!
