Two signals can mean different things
A microphone and one mono instrument give MiniFuse 2’s two physical inputs clear individual jobs. A hardware keyboard recorded through separate left and right audio outputs can instead require both input channels. If the plan is that stereo instrument plus a microphone at the same time, the desired arrangement asks for more physical inputs than this interface provides.
The connector labels do not multiply the channels
Arturia specifies two combo Mic/Inst/Line inputs. XLR and jack connection choices let each input serve different equipment; they do not turn a combo socket into two simultaneous recording channels. Use the documented signal-type and connection guidance for the actual microphone or instrument.
The separate five-pin MIDI connections carry control information to or from instruments. They do not add an analogue socket for the keyboard’s sound. The listed stereo loopback channel likewise concerns virtual audio routing, rather than a third place to plug the microphone.
A compact interface for a defined pair
Choose MiniFuse 2 when two physical input channels match the actual recording session, whether that means a voice/instrument pair or a stereo source. A creator building music for a character project may value MIDI alongside that small audio arrangement. If three or more simultaneous physical signals are essential, investigate an interface with the needed inputs instead of hoping a different cable name creates another channel.
