Harmonisation Modes And Description Of The Algorithms; Automatic Chord 1 - KETRON SD1 User Manual

F8 Vocalize To Arranger: the buttons controlling the Arranger may be assigned a different algorithm to be chosen among those available for
the harmonisation mode selected in F3 Modes. In the centre of the display the Start, Stop, Arrange A, B, C, D, Fill 1,
2, 3 and Break sections can be selected with the CURSOR +/- buttons, and one of the available algorithms can be
assigned to them acting on the VALUE +/- buttons. Pressing again the F8 Vocalize To Arranger button takes you
back to the Vocalizer Edit menu. The algorithms assigned to the Arrange A, B, C, D buttons are still valid while
replaying a Midifile or a Song. This allows you to instantly call up a different voice algorithm. The F10 Status param-
eter must be set on Internal Active to avoid confusion or errors, i.e. to avoid that the Vocalizer is controlled by a
MIDI track. Further to assigning an algorithm, you may also select the Off condition which will disable the Vocalizer
for this specific button only. If neither an algorithm nor the Off condition is selected, two dashes will indicate that
for this specific button the general Vocalizer conditions apply. Vocal Set 1, called up when the Vocalizer is activat-
ed, assigns Arrange A and C the Harmony Right mode, and Arrange B and D the Unison mode by default.
F9 Vocalize Lead On: This is present only on the first ten algorithms of the Automatic Chord 1 and Fixed Interval mode. It tunes the third
voice generated by the Vocalizer in unison with the singer voice. It is deactivated by pressing the F9 Vocalize Lead
On function key again.
F10 Status: pressing repeatedly the F10 button modifies the Vocalizer status switching from Active to Internal Active, None or
Inactive. "Active" indicates that the Vocalizer is active and able to receive data from the keyboard, via MIDI and from
the sequencer. "Internal Active" assures that the Vocalizer is controlled only by the keyboard and by the algorithms
assigned to the control buttons of the Arranger, and not via MIDI and not via the sequencer. "None" completely deac-
tivates the SD1 Vocalizer but still transmits the information for the Vocalizer control to the MIDI Out, to be able to
control a similar external unit. "Inactive" deactivates the Vocalizer control via the keyboard, but not via MIDI.

HARMONISATION MODES AND DESCRIPTION OF THE ALGORITHMS

After you have selected a harmonisation mode using F3 Modes, at the centre of the screen the relevant algorithms you can select using the
CURSOR +/- push buttons are displayed. In the following we have a short description of the single algorithms for each mode.

AUTOMATIC CHORD 1

The voices added by the Vocalizer depend on the chord recognised on the keyboard area to the left of the splint point, independently from its
inversion, and on the note sung, of which the intonation and the inversion, if any, will be determined according to the recognised chord. If the
note sung is extraneous to the chord, this note will not be reproduced by the Vocalizer but will be present as a direct audio signal. In this case
the Vocalizer reproduces a voice with a note that is as near as possible to the note sung, but compatible with the chord. If the note sung belongs
to the chord, the Vocalizer creates the harmonisation as a function of this note, producing the single inversions. The single algorithms can vary
the position of the note sung within the chord and can place it to the centre, on the third or on the fifth. Modifying the note sung can, as a con-
sequence, cause also the inversions to change. The following algorithms are available for Automatic Chord 1:
Trio Standard: This maintains the note sung in the centre of the chord. If the Vocalize Lead is active (On), the note sung is doubled.
Trio Up: This maintains the note sung in the bass of the chord. If the Vocalize Lead is active (On), the note sung is doubled.
Trio Down: This maintains the note sung in the treble, generating the two voices under it. If the Vocalize Lead is active (On), the note sung
is doubled
