*It may be the case that you will need a separate MIDI connect device for your computer instead of trying to use the XV's USB to MIDI. Then connect the INput of the XV to the output of that device, connect the EWI to the same device's input. Either that or consult the XV manual to see if there is a way to make its USB MIDI connect a standalone situation such that you may connect the separated controller (the EWI) direct to computer input.

Have you hooked the Audio Output (stereo) of the XV to the Line Input of your computer soundcard or sound device? If not, you won't be able to monitor the sounds of the XV correctly, nor record them to Audio when you need to make an Audio mp3 or wav file of your work.

On the MIDI connect situation, the Input in the BIAB MIDI select window should be set to whatever input that your EWI is on.

Output should be set to whatever output your XV is on.
