The Portamento manual produces continuous pitch shifts
just like those produced when the finger slides up and
down a violin string. The 2% octave range becomes higher
toward the right. There are four Portamento voice selector
tabs and except for the Astro tab they can all be combined
with each other. If the Astro tab is set it cancels all the
others.
PORTAMENTO VOLUME CONTROL
This permits a separate volume control.
On the panel above the solo manual and selectors is a
series of tone levers which control the voices (instrument
sounds) which will be heard when the keys are depressed,
as well as many of the effects. They are divided into groups
for upper, lower and pedals, so that different registrations
can be set for each.
Upper Manual Levers 12 voices
Lower Manual Levers 5 voices
Pedal Levers 3 voices
PITCHES OR FOOTAGES
The DK-40B has five different pitch levels, indicated by
the numbers 16', 8', 5%', 4' and 22", These are standard
musical abbreviations showing the tone's pitch in relation
to the fundamental (written note). An 8' tone will sound
just as it has been written. As the numbers increase, the
tones lower. A 16' tone (meaning that the wave length of
the vibrations are twice as long as 8', or half as fast) will
provide a tone exactly one octave lower than the written
note. Similarly, 5%' tones are a fifth higher than the written
note, 4' tones one octave higher, and 2*5' tones one octave
and a fifth above the fundamental. Tones at octave intervals
from the written notes are "consonant harmonics," while
all others are ''dissonant."
