I obtained quite a cheap DJ Controller. My ambition was to use it with
Cinelerra for editing. I was quite surprised it was actually MIDI based. I
have tested midi2input, it has a steep learning curve. But given they have
examples how to do it for kdenlive and olive, it is an engineering approach
in making a device available.
>From what I have seen from "Mixxx" which fully integrates with multiple
midi devices, having an integrated mapping would make sense. But that would
also suggest to have they keyboard mapping as a first class citizen as
well.
