Design of the CP4 STAGE & CP40 STAGE

Makeup

In terms of sound production, the CP4 STAGE and CP40 STAGE each comprises three blocks — namely, the
controllers, the tone generator, and the effect unit.

Controllers

Controllers
In order that it may be played, the instrument features a range of controllers such as the keyboard, pitch
bend wheel, modulation wheel, and sliders. Performance data reflecting the pitch of each key played and
the velocity (or strength) with which it was played is sent to the tone generator in the form of MIDI messages.
Data generated by operating the wheels, sliders, pedals, and the like is also sent in the same way.

Keyboard

The keyboard is the main controller used to send performance information to the tone generator. Using the
[-] and [+] TRANSPOSE buttons, you can change the pitches of the keys in semitone units.

Pitch Bend Wheel

The pitch bend wheel can be used to control the pitch of played
notes in a continuously variable manner. Notes are bent upward
when you push the pitch bend wheel away from you and vice
versa. When you release this wheel, the finger slot at the center will
automatically spring back to the original position, and the pitch will
return to normal. The pitch-bend range — that is, the degree to
which pitches can be varied using this wheel — can be set on the
Play Mode screen (page
In addition to pitch bending, you can also assign control of an
insertion effect (page
so, use the Controller screen
Edit area.

Modulation Wheel

The modulation wheel is normally used to add vibrato and other
suitable effects to the played notes. The more the finger slot is
pushed away from you, the greater the intensity of the effect and
vice-versa. The effect is, therefore, minimized when the slot is
closest to the front of the instrument. If you do not want to apply the
modulation wheel's effect, it should be returned to this position.
In addition to applying modulation, you can also assign control of a
parameter from an insertion effect
wheel. To do so, use the Controller screen
Performance Part Edit area.
