CONTACT / SUSTAIN
Th is Page allows you to adjust the Parameters which aff ect the Virtual Multi-
Contacts and the Sustain eff ect for the UPPER and LOWER Parts.
VIRTUAL MULTI-CONTACT
OFFSET TIME
Setting Range: -64 ~ ±0 ~ +63
Th is allows you to set the time when a note is “ON”until complete contact is made.
A higher value causes a longer Attack time and a shorter Release time.
DAMPING
Setting Range: 0 ~ 31
Th is allows you to control the damping rate of the Virtual Multi-Contacts.
Th e higher the value, the more pronounced the Key Click.
MODE
Th is allows you to select how the Virtual Multi-Contacts (“VMC’s”) will sound
when keys are depressed.
Random .......... When a key is depressed, each contact of the VMC’s will connect in a random
order at the shallow point, and all the contacts are fully made when the key
reaches its deep point.
Velocity ........... When a key is depressed to its deep point, each contact of the VMC’s is made by
a time diff erence depending on the velocity.
DEPTH
Setting Range: 0 ~ 127
Th is allows you to adjust the amount of time for each VMC to sound when a key
is depressed.
At “0” all the VMC’s sound simultaneously. Th
e higher the value, the longer the
time interval between contacts.
UPPER & LOWER SUSTAIN
Th is allows you to add a smooth decay to the UPPER & LOWER Drawbar tones.
SWITCH
Settings: Off , On
Th is allows you to turn Sustain “ON” or “OFF” on the selected Part.
LENGTH
Setting Range: 1 ~ 5
Th is allows you to adjust the length of the Sustain eff ect for the selected Part.
IMPEDANCE
AMOUNT
Th is allows you to adjust the amount of volume reduction when keys are depressed
and held and other keys are depressed on a Tone Wheel organ.
Off ...............No volume reduction.
Half .............The volume will be reduced by a small amount.
Full ..............The volume will be reduced by the full amount.
WHAT ARE CONTACTS?
When a key is depressed on a tone -wheel
Hammond Organ, it closes 9 small electrical
switch contacts. These 9 contacts represent the
9 pitches provided by the Drawbars. The contacts
are closed and opened by means of 9 horizontal
flat springs which touch 9 busbars. When a flat
spring touches a busbar, electrical contact is
made and the harmonic is permitted to sound.
Since the 9 busbars are physically separated, the
harmonics do not all sound simultaneously, but
in succession. This can be heard most clearly by
selecting one of the four Manual Drawbar sets of
a tone-wheel organ, pulling all of the Drawbars
out to their maximum volume setting and slowly
pressing a playing key. Each of the harmonics will
add in a sequence from highest to lowest until
all 9 frequencies will be heard when the key is at
the bottom of its travel. The “Key-Click” on tone-
wheel Hammond Organs is due to these physical
characteristics. Also, if a key is released quickly
it will bounce at the time of contact, creating an
eff ect known as “Key Bounce” or “Chattering.”
WHY LESS RELEASE KEY CLICK?
One of the characteristics of the key contacts
on a tone-wheel organ is, the Release “click” is
somewhat softer and less intense than the Attack
“click.” This characteristic is replicated on the SK
PRO.
SUSTAIN
The word “Sustain” has a different meaning for
an electronic organ than for a synthesizer. On an
electronic organ, “Sustain” refers to a note or noes
continuing to sound and smoothly decaying after
the key is released. This is called “Release” on a
synthesizer.
WHERE IS THE PEDAL SUSTAIN?
The Pedal Sustain is controlled from the INTERNAL
ZONE FUNCTION Mode in the COMBINATION Edit
Mode due to the fact that Pedal Sustain aff ects any
Voice Section allocated to the PEDAL Part and not
only the ORGAN Section. See page 78 for more
details.
