TONE-WHEEL SET
The Tone-wheel Sets are divided into the
Manual Keyboard and the Pedal Part. This is to
give the Pedal Part the Decay (= the sound
gradually fading out while pressing the key) or
Sustain Effect. (= the sound gradually fading
out after the key is released).
To fully enjoy playing this keyboard, please read the following section
of this manual.
See the illustrated System Structure of your keyboard on the left page.
TONE-WHEELS
The sound source or “engine” of Hammond Organ is the Tone-wheels. They are
like the strings and pick-ups on the electric guitar. While running, each of the 96
Tone-wheels keeps oscillating at a different pitch/frequency.
KEYS
Each of the sound signals made by the 96 Tone-wheels is switched at each key.
Each signal corresponding with each pitch and harmonic is distributed to each
key (as an example, 9 signals for the manual keyboard). The keys are switched
on and off by depressing (= touching) and releasing the keys.
DRAWBARS
The Draw-bars prepare the basic sounds. Each bar adjusts the value of each
harmonic (as an example, 9 harmonics for the manual keyboard).
PERCUSSION
The Percussion makes decay sound, synchronizing with the key touch of the UP-
PER part.
VIBRATO/CHORUS
Vibrato gives vibration to the pitch. By mixing the vibrato sound with the funda-
mental sound, Chorus effect is obtained.
NOTE: On this keyboard the scanner circuit of the B-3/C-3 is simulated, which gives
more effects than the changes of the pitch.
TUBE AMP
Having a real tube in the Amp gives the XK-3C a unique tube sound. By chang-
ing the amount of the drive you can obtain various tube sounds from “clean” no
clipping, to the hard-distorted fuzzy and raspy “overdrive”.
The Pedal Part, however, is designed not to pass through the Vibrato/Chorus or
the Tube Amp, in order to obtain the clear Bass-line.
EFFECT LOOP
If you connect an effector to the effect-loop input (send/return) which is located
on the back of the keyboard, it will no pass thru the overdrive tube amp.
EQUALIZER, LESLIE and REVERB
The sound comes out of the output terminal, after passing the spatial effects: the
Equalizer (for tone regulation), the Cabinet (for the rotating speaker effects) and
the Reverb (for resonance). The built-in Leslie Effect does not work at the Leslie
11-pin terminal.
NOTE: The built-in Leslie Effect is designed to smoothly simulate the rotations of the
two rotors.
HARMONICS
Harmonic is a pitch of a different ratio to a cer-
tain pitch; for example, the one octave higher
C to the middle C. The more Harmonics, the
brighter and richer sound is obtained.
