Adjusting The Sound In Real Time (Harmonic Bars) - Roland VK-88 Owner's Manual

Adjusting the Sound in Real Time
(Harmonic Bars)
The harmonic bars are controllers for creating the basic structure of the organ sound.
The VK-88 provides nine harmonic bars for the upper part and lower part
respectively, and two harmonic bars for the pedal part. By sliding the harmonic bars
in and out you can create a variety of tonalities.
In addition to creating the tone, the harmonic bars are also used to adjust the volume
balance between the upper, lower and pedal parts.
fig.01-14
The numbers appearing on the harmonic bars allow you to rapidly set the bars to the
desired setting. If you push a harmonic bar inward until no number is visible, its
volume will be "0," and no sound will be heard. If you pull a harmonic bar all the
way out, the volume will be at the maximum.
A sine wave (pure tone) of differing pitch is assigned to each of the harmonic bars,
and you can create a variety of sounds by mixing these sine waves.

When percussion is on, the 1'
pitch will not be produced.
Percussion sounds are applied
only to the Upper Part.
NOTE
When all of the harmonic bars
are pushed in, which sets the
volume to "0," no sound is
played even when you play
the keyboard. However, when
you play crescendo using the
D BEAM Controller or other
effects, the organ's Upper and
Lower Parts are played, and
the crescendo effect is applied.
