Setting Up
To fully utilizing this unit, read the following detailed explanations about the various func-
tions for creating music.
ORGAN SECTION
TONE-WHEELS
Th e sound source or “engine” of the classic Hammond Organ are the electro-magnetic
Tone-Wheel Generators. On this keyboard, the Tone Wheel engine is replicated digitally.
While the power is on, each of the 96 virtual Tone-Wheels keeps oscillating as they did
in the vintage Hammond Organs.
KEYS
Th e tone signals created with the 96 virtual Tone-Wheels are “switched” at the keys.
To each key the signals corresponding to the pitch and harmonics (for example, 9 sets on
the manual keyboard) are distributed, and when you touch or release a key, the switch
connects or cuts the tone signals.
DRAWBARS
Each Drawbar represents a fundamental harmonic. Each bar adjusts the value of each
harmonic. Th
ere are 9 drawbars corresponding to 9 diff erent harmonics.
TOUCH-RESPONSE PERCUSSION
Th e Percussion creates a decaying sound on the UPPER manual.
VIBRATO & CHORUS
Th e Vibrato & Chorus gives depth and richness to the organ sound by slightly varying
the pitch (Vibrato), or doubling the voice by mixing the original sound, with a duplicate,
slightly detuned one (Chorus).
OVERDRIVE
Th e Overdrive creates distortion as if an amplifi er was being driven beyond its limits.
MULTI-EFFECTS
Th e Multi-Eff ects create various eff ects such as tremolo and Wah.
EQUALIZER, LESLIE, REVERB
Th e built-in Eff ects are as follows: an Equalizer for sculpting the tonal response, a Leslie
Eff ect for rotary speaker eff ects, and Reverb.
(Th
e built-in Leslie Eff ect is disengaged when a physical Leslie is connected to the 8-pin
terminal.)
EXTRA VOICE SECTION
SOUND ENGINE
Th e Extra Voice section is the sound engine for playing piano and other musical instru-
ments. It is independent of the Organ Section.
EFFECTS
You can add Overdrive, Multi-Eff ects, Equalizer and Reverb to the Extra Voice Section.
MASTER EQUALIZER
Th e combined signal of Organ and Extra Voice is routed through the Master Equalizer.
Allowing you to tailor your sound for the provided venue, amp, sound system or record-
ing. Th
e settings are not saved in patch memory.
TONE-WHEEL SETS
The Tone-Wheel Sets are divided into the
Manuals and the Pedal Part. This is to give the
Pedal Part the Decay (= the sound gradually
fading out while pressing the key) or Sustain
Eff ect. (= the sound gradually fading out after
the key is released).
HARMONICS
Harmonic is a pitch of a diff erent 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.
