V oices and User Voices
One of the fundamental features of the SD5 is its sound quality and consequently the synthesis technology exploited that is based on multi-
samples processed by subtractive synthesis, frequency modulation and additive synthesis. The samples have been developed over the last few
years by a team of international programmers. For example, the impressive Acoustic Piano voice, exploits up to 64 samples painstakingly arran-
ged along the keyboard on two different levels of dynamics. For each voice the musician can use up to a maximum of two oscillators at the
most, but the quality of the single samples is such that most of the voices use only one oscillator. This aspect directly affects the polyphony,
which is not halved: the 64-note Polyphony is for the most part a reality! The synthesizer of the SD5 exploits a 24 dB/octave LPF filter with three
envelopes, two LFO's and a complete modulation section. The FM synthesis is based on an algorithm with four operators of which two are car-
riers and two modulators, while the additive synthesis is used for creating the Hammond organ voices in the Drawbars mode. We have inten-
tionally restricted access to the synthesis parameters especially for FM since it is a complicated system and was used only at the manufactu-
ring stage to create a few of the sounds which are offered and are generally ready to use.
The SD5 also has a bank of factory 'Preset Voices', a General MIDI bank (used again for the Styles) and a bank of 110 User Voices. The latter is
where you store your own voices using the General MIDI or other voices as your starting point.
Note: Remember too that the Preset Voices, namely the richer life-like voices, can be used only by the Lower and Right section for playing
manually, whereas the accompaniment tracks will use only the Voices in General MIDI format to maintain the compatibility with GM standards.
For the Right part the Programs allow the use of up to four Voices at the same time, split or layered over the keyboard and with individual edi-
ting parameters for each. It is also possible to set a second voice to be layered with the main voice (Second Voice).
To call up the Voices you can use the control panel push buttons V
VO OIIC CEESS aanndd U USSEER R V VO OIIC CEE, or you can create a list of customised Voices with the
most frequently used voices (1 Touch).
There is a specific mode for the drums that allows you to play the drum sets right over the whole keyboard. The SD5 uses drum sets derived
both from samples and grooves created by recording famous drummers or percussionists live. These then were processed via a proprietary pro-
cedure to create a drum set, but with “real” percussion instruments (Live Drum). Both types of drum sets can be used by the musician live, right
over the entire keyboard.
CALLING UP THE VOICES
The two rows of six push buttons called V VO OIIC CEESS are used to call up the voices according to the family in which they belong. When a family is
selected using the push button, the display shows five Voices to the left and five Voices to the right, which can be selected by pressing the func-
tion button associated to that voice. The last Bank of Voices is dedicated to the Drawbar voices if you press the U
USSEER R V VO OIIC CEE push button.
When the SD5 reaches the last page of Voices available, if you press the same push button for that family of voices again you will return to the
group of voices of the first page. This last move (unlike the others) cannot be made using the PPA
AG GEE ++ and PPA AG GEE -- push buttons.
The V VO OIIC CEESS push buttons do not call up the preset voices alone.
If the LED of the U USSEER R V VO OIIC CEE push button is lit, you get the bank of user editable voices. The 110 voices in this bank can be called up using the
'V VO OIIC CEESS' push buttons in groups of eight at a time.
If the LED of the D DR RA AW WB BA AR R push button is lit, the last bank of Voices calls up a single Organ voice only.
If the LED of the PPR RO OG GR RA AM M push button is lit, then the V VO OIIC CEE push buttons call up the 'Program' memories.
If the LED of the O ON NEE TTO OU UC CH H push button it lit, then the first row of V VO OIIC CEE push buttons calls up one of the six pages that make up the One Touch
memories (where your favourite voices are stored).
SECOND VOICE
The SD5 offers the facility to create a layer using two voices for the section to the right of the keyboard split point. The display shows the name
of another Voice called the 'Second Voice in small letters under the selected main Voice's name. To activate the 'Second Voice' press the 22
N ND D
V VO OIIC CEE push button (the LED lights up).
As a default setting, the SD5 already has a Second Voice assigned to each lead voice, but this voice can be modified. This editing procedure can
be carried out once the Second Voice is switched on.
From the main page press R
Riigghhtt M Meennuu and then PPA AG GEE ++.. From the menu displayed, select FF44 22
nndd
V Vooiiccee EEddiitt
Select the group to which the new voice for the Second Voice belongs using the V
VO OIIC CEESS push buttons. Only the name of the first Voice of that
group will appear.
Use the equivalent function buttons (F1-F10) to select the other Voices that follow the first one in the group selected.
To modify the octave of the Second Voice, use the TTR
RA AN NSSPPO OSSEER R ++//-- push buttons that will act as TTR RA AN NSSPPO OSSEER R push buttons while the Voice is
selected.
To modify the volume of the Second Voice, use the D
DA ATTA A C CU UR RSSO OR R push buttons for the volume while the voice is selected.
This editing procedure can be repeated for each voice assigned as the Second Voice. Remember to save the modifications made (which would
otherwise be lost when the SD5 is turned off and default to those set by Ketron) by proceeding as follows:
Press SSA
AV VEE
Select FF66 22 nndd V Vooiiccee
Confirm the procedure using FF110 0 SSaavvee, thus the modifications are saved permanently in Flash RAM.
To restore the original settings of the Second Voice preset by Ketron, use function push button FF99 D Deeffaauulltt instead of confirming the procedure.
