Hi, I have a Roland JDXi synth (no hardware problems, plays fine in Windows on different usb ports) which has 2 modes
Vendor for Audio and midi Generic for midi only The problem is that when in Vendor mode, the JDXi locks when connected to usb ,until I connect it ,to Jack. Then it starts playing fine, but if I disconnect it from Jack it stops again. When using an app like Ardour (on alsa mode) the JDXi plays only when is on playback or recording mode(no duplex) Bellow is a link for the lsusb -v https://1drv.ms/u/s!AlZVbQKqWCqsgR88M2Ul-x_sTo29 alsactl version 1.1.2 (couldn't find the alsa version ,is this the correct one?) rt-kernel 4.4.6-rt13-avl2 (from AVLinux)
