Just to be clear, as you ask I'm sending two MIDI commands, same CC,
different value:
Debug [Controller]: "MIDI status 0xB0 (ch 1, opcode 0xB), ctrl 0x19, val
0x7E"
Debug [Controller]: "MIDI status 0xB0 (ch 1, opcode 0xB), ctrl 0x19, val
0x7F"

With the first I tell mixxx to scroll down, with the latter to scroll up.
The learning learns the first as scroll down, then when I attempt the
learning for the scroll up, it deletes the first one, I can see it from the
XML. I guess the logic is to delete older learnings for the same <midino>
or CC.

I think the logic should be changed for controls that do not require a
value: unlike faders, a "scroll down" or "switch view" need only sense a
CC+value couple. However I think there are cases where you only need to
watch the CC and cases where you exactly want to map a command to CC+value.
But that's my 50 cents.
