Re: ALSA MIDI on Raspberry PI: no events from input device (USB keyboard)

So, I've seen that a working MIDI keyboard "creates" this device:

/dev/snd/-midiC0D0

while my problematic MIDI keyboard has instead:

/dev/snd/-midiC1D0

see that "C1"?
This has to do with "amidi --dump" requiring "--port hw:1" instead of
the usual "--port hw:0"

Now:
How can I configure ALSA (.asoundrc?) in order to correctly "map" that
"port hw:1", so it can be used by a MIDI softsynth, which expects
"hw:0"?

Thanks!
