Because the keys respond electrically to touch and do not move, you must keep your fingers completely off the keys you don't want down or you get wrong notes. This was fairly bothersome on the 1000, where the slightest brush of a key would trigger it. A small pot on the 3000 allows you to adjust the amount of touch the keys need to trigger a note. After setting it up, we had much less trouble with false notes. Players of open-hole instruments normally keep their fingers off open holes and will feel more at home with the EWI than sax players, who usually rest their fingers lightly on open keys. To ameliorate the situation, Akai offers a snap-on finger-rest, the EWI-FR providing three spring-loaded keys for each hand.
