KEY/SENSOR RECALIBRATION

If the EWI USB is not responding as expected (if you are encountering stuck notes, tuning problems, unresponsive

keys, etc.), do the following:

1. Hold the EWI USB by its plastic casing only. Do not touch any of its metal parts.

2. Press and hold the RESET BUTTON. After five seconds, the STATUS LED will flash rapidly.

3. When the STATUS LED stops flashing, release the RESET BUTTON.

UPDATING THE FIRMWARE

1. While holding down the RESET BUTTON, connect the EWI USB to your computer with the USB cable

(included). Be careful not to touch any of the metal keys, plates, and rollers as you do this. After you see the

STATUS LED flash green, you can release the RESET BUTTON.

2. Download any available firmware updates from http://www.akaipro.com

3. The firmware will be a standard MIDI file with a .MID extension. Play this file with your preferred MIDI file

player (we recommend using Windows Media Player or Quicktime). Make sure the EWI USB is selected as

your application’s MIDI Out port. As it plays, sending it to the EWI USB, the STATUS LED will turn red.

4. Once the STATUS LED flashes green again, unplug the EWI USB.

5. Reconnect the EWI USB. The STATUS LED will light up red.

6. Hold the EWI USB by its plastic casing only

. Do not touch any of its metal parts.

7. Press and hold the RESET BUTTON. After five seconds, the STATUS LED will flash rapidly.

8. When the STATUS LED stops flashing, release the RESET BUTTON.
