Yamaha MX (MX88): Under Ubuntu 16.04 and Ardour 5.12, is it possible to pick up audio output from “USB to host”? Settings in such case?
I once managed to manage audio over USB with a Behringer Xenyx mixer, using JACK. When hooking up the MX with Ardour for MIDI I use ALSA. (Works right out of the box.) My ignorance, but I guess JACK and ALSA are mutually exclusive, so perhaps you can’t have both, audio and MIDI, at the same time?
