b.) Use MIDI without controlling/affecting XR18 mixer / MIDI-USB interface mode
Make sure the XR18 is connected. At present (-> March 2015) MIDI settings are only available via
XR18 PC/MAC/LINUX application.
2. Launch XAir app and open “Setup” menu. Click on “Mixer” tab to find “MIDI Config” menu.
Ensure “USB-DIN Pass Thru” is checked
All other settings (e.g. USB Rx, DIN Tx,…) are fully ignored (no matter if checked or not)
“USB-DIN Pass Thru” mode means:
o All MIDI signals at front-panel “DIN IN” always reach computer via USB
o All MIDI signals from computer available on “DIN OUT”
o XR18 mixer is never affected (-> MIDI signals pass thru)
USB connection can carry audio and MIDI signals simultaneously
Application examples (hook-up diagrams see next page)
1.) External MIDI Keyboard connected to DIN ports + VST audio on XR18 via USB returns
2.) DIN OUT provides MIDI commands from computer to affect external MIDI devices
