Firmware Update

Important note

The MIDI Bridge only accepts a firmware update when *no* MIDI traffic has occurred since power-up, otherwise it will simply try to deliver the MIDI data on the other port as in normal operation.

  • Fully disconnect the MIDI Bridge.
  • Connect MIDI Bridge to PC only (which port used on the MIDI Bridge does not matter).
  • For Linux Users, using amidi (www.systutorials.com/docs/linux/man/1-amidi/):
    • find hardware port ID with amidi -l, say it was hw:1,0,0 for example
    • send SysEx with amidi -p hw:1,0,0 -s nlmb-fw-update-VX.YZ.syx
      (X.YZ must be replaced with the actual firmware number)
  • For Windows/Mac users:

If the firmware update was successful, the MIDI Bridge will show that by both LEDs blinking fast in bright GREEN color and then will reset itself after 5 seconds, afterwards showing the new Firmware Version during startup.

If the update failed, try again the full cycle from step 1 (note: try using also the other port of the MIDI bridge).

  • Optional Firmware Version Check (besides the visual Firmware Version Display):
    • Software like MIDI Tools must be restarted and then will show the new firmware version of a connected Bridge in the setup screen.
    • on Linux, use the command usb-devices | grep -C 6 -i nonlinear

Windows hint

To remove stale entries potentially causing wrong display of the device name, go to device manager, select show hidden devices, then delete all NLL-Bridge entries. Do this while the MIDI Bridge is *not* plugged in, of course.
