There is usually only a Roland UM-1G as an additional midi device. The Edirol UA-5 I mentioned earlier has midi, too, but is typically powered off/not connected. When I checked with UM-1G and UA-5 disconnected it made no difference. Unplugging the Axe-Fx II led to the error message again. The soundcards have fixed card numbers.

There is a further connector (called MFC port) for a proprietary connection to a midi foot controller (MFC) of the same manufacturer. The MFC port can be used to sent and receive data to and from the midi foot controller. Midi data from the MFC is forwarded to the midi out DIN connector, midi data at the midi in DIN connector is forwared to the MFC. The midi-over-USB data can be routed by a software "switch" to the DIN connectors and the MFC port: data at the midi in port (DIN connector) is forwarded to the midi-over-USB; data coming in over midi-over-USB would be forwarded to the midi out port (DIN connector). This applies also to the data coming from and going to the MFC port which is tied to the "classical" midi ports.
