Chapter2: Basic Operation
Adjusting the Touch Sensor Sensitivity
The EWI4000s uses Touch Sensor keys, not mechanical switches. In regular use, there
is no need to adjust the Touch Sensor sensitivity, because it is adjusted at the factory.
But it may not respond to your key touch correctly (The Program/Data display may
show some numbers while in Play mode instead of showing the Program number)
depending on changes in temperature, humidity or the static electricity from the floor.
In this case, you will need to adjust the Touch Sensor sensitivity.
1. While in Play mode, touch the Note keys (K1, K2, K3), the earth plate,
and the Octave roller with the fingers of your left hand.
2. If there are numbers shown on the Program/Data display, turn the Touch
Sensor’s sensitivity volume clockwise until the numbers disappear.
If there are no numbers on the Program/Data display, turn the Touch Sensor sensi-
tivity volume counterclockwise until numbers are shown, and then
turn it clockwise until the numbers disappear, and then set to turn it a
little more clockwise. Be sure that any number is not shown on the
Program/Data display if you touch many keys with both your left and
right hands.
( ! ) Don’t touch the [Program] key.
