USING THE MOUTHPIECE
„ Mouthpiece
Hold the mouthpiece gently in your mouth with your teeth, and exhale so
the breath is passed through both ends of your mouth. The EWI4000s
detects this wind pressure with the breath sensor and expresses the
change in sound volume and character. The EWI4000s unique breathing
structure is designed so that very little breath is required to pass through
the instrument. You can use various breathing techniques to sustain or
shape notes for powerfully expressive performances.
„
Vibrato
There is a vibrato sensor in the MOUTHPIECE. You can produce a vibrato effect by gently biting the
MOUTHPIECE. Do not bite too hard as this may damage the vibrato sensor or the MOUTHPIECE itself.
„ Tonguing
You can create small bursts of air by tonguing the mouthpiece for even more expressive control.
Note: Adjust the S (Sense) SENSOR ADJUSTMENT KNOB to create different tonguing nuances.
USING THE PITCH BEND PLATES, GLIDE PLATES, & HOLD & OCTAVE BUTTONS
„ Pitch Bend Plates
By touching the PITCH BEND UP PLATE or PITCH BEND DOWN PLATE with your
thumb (while also touching a GROUNDING PLATE), you can raise or lower the pitch
of the note being played. Adjust the pitch bend range with the W (Width) SENSOR
ADJUSTMENT KNOB.
Note: Before you get accustomed to using these plates, you may produce
unexpected sounds by touching them accidentally. You can adjust the position of
each plate by loosening its screw.
„ Glide Plate
By moving your thumb across the OCTAVE SHIFT ROLLERS
while touching the GLIDE PLATE, you can achieve a “glide”
effect, which will smoothly and continuously slide the pitch
being played up or down. This is known as portamento.
Adjust the glide time using the T (Time) knob on the GL
(Glide) section of the EWI4000s.
Note: Before you get used to controlling this plate, you may
produce unexpected sounds by touching them accidentally.
