I tried, in /etc/modprobe.d/alsa-base.conf,
options snd_hda_intel index=0
but that failed at boot-time with
[2.375487] usb 3-1: Product: Keystation 49e
[2.782508] usb 3-2: Product: ProKeys Sono 88
...
[5.496058] cannot find the slot for index 0 (range 0-1), error: -16
[5.496129] hda-intel: Error creating card!
[5.496174] HDA Intel: probe of 0000:00:1b.0 failed with error -16
so I tried the other way round, to lower the slot-priority of
the usb module; you can find out which module is involved by
cat /proc/asound/modules
with the MIDI-kbd switched off and then switched on and noting
the difference; it's the snd_usb_audio module. So I added a
options snd-usb-audio index=-6
line. I tried index=-2 and even index=-4 but they weren't enough.
But -6 works :-)

man modprobe.conf reckons:
Note that module and alias names (like other module names) can
have - or _ in them: both are interchangable throughout all the
module commands as underscore conversion happens automatically.

I don't understand why it was ever considered desirable to
write raw audio data to a MIDI device. The advantage of USB
was supposed to be that each device clearly announces itself
and its requirements. Maybe I should be thankful that it
doesn't write raw audio data to the raw disc devices.
