For compatibility and portability I'd suggest sticking with either MIDI or
HID. That way you can interoperate with any existing Mixxx 1.11.0 installs
and it will require no/minimal code changes to Mixxx. Adding a custom pipe
also present UI challenges around enumeration and selection of which pipe
to use. We already have a good system in place for MIDI / HID device
enumeration / UI selection.
Best regards,
RJ
