Internal Voices
LetÕs explore the onboard instruments. When the PC88 is Þrst turned on, the button labelled
Internal Voices
in the group of four buttons under the left side of the label
Sound/Setup Select
,
is lit. Now the group of 16 numbered buttons to the immediate right of this can be used to
choose from 16 families of instruments. Button number 1,
Classical Piano
, is lit right now. This
is the selected voice; its name appears in the display. Press the other numbered buttons to select
among the other voices. While youÕre doing that, play with the modulation wheel (the second
one in from the left, or ÒWheel 2Ó) and the sustain pedal, and see how the sounds change. On
most of the organ sounds, for example, pushing the modulation wheel brings in a rotating
speaker effect.
To select a different instrument within a family, use the
Previous Group
and
Next Group
buttons. Each family contains 4 different instruments, arranged in Groups labelled (as youÕll
see on the display) A through D. (Press
Previous Group
and
Next Group
simultaneously at
any time to return to Group A.) Press the Select button marked
Piano & Strings
, and then press
the Previous Group button until the upper-right corner of the display says
A06
. This is a
layered sound of a bright stage piano and a string pad. Hold a chord and move the slider in the
Assignable Controllers
section labelled
C.
Listen to how the timbre changes.
Assigning Controllers
LetÕs have Wheel 2 do something else. Find the group of buttons at the top of the panel labelled
Zone Parameters
. The topmost right button is labelled
Controllers
. Press that button so that its
light comes on. The top line of the display reads
Wheel 1 Up
. Now press the
Controllers
button again, but this time hold it down while you move the modulation wheel slightly. The
display changes to read
Wheel 2
. This is an example of a feature called ÒIntuitive EntryÓ
which makes it possible to adjust parameters quickly without having to scroll through pages of
them. The PC88Õs display now looks like this:
Zone:1|||Wheel|2|||
Ctrl|Num:|1|Mod|Whl
Right now, the lower line on the display tells us that Wheel 2 is controlling Modulation (MIDI
Controller #1). Turn the big black knob on the panel under the label
Data Entry
Ñ weÕll be
calling this the ÒAlpha WheelÓ Ñ clockwise until the lower line of the display says
Ctrl
Num: 10 Pan
. Wheel 2 has now been conÞgured as a pan control. Play a passage of short
notes while you quickly move the wheel. The notes will appear at different points in the stereo
spectrum depending on the position of the wheel.
Exiting from PC88 Menus
You can exit from any PC88 menu by going directly to Internal Voices mode or MIDI Setups
mode. You do not have to explicitly exit from the menu; the PC88 will change modes
automatically, as soon as you press the
Internal Voices
or
MIDI Setups
button. For example,
to return to Internal Voices mode without changing the controller assignment in the above
example, press
Internal Voices
(which will begin blinking), then press one of the Sound Select
buttons,
Harpsichord
for example. Notice that the
Internal Voices
button stops blinking when
you select a sound. (Since we didnÕt save the controller assignment when we selected this
Internal Voice, the wheel resumes its modulation function.)
