The control's settings correspond to the Vibrato Switch available on Hammond tonewheel organs
equipped with the Selesctive Vibrato system (Hammond A-100, B-2, B-3, C-2, C-3, RT-3 and similar).
The setting names beginning with
V
, indicate
Vibrato
modes, while the modes beginning with
C
stand
for
Chorus
modes. The number next to the letter V or C, generally, refers to the perceived “depth” of
the chorus or vibrato effect. The larger the number, the stronger the effect.
You may also click on the mode name labels to change the current MODE setting.
•
HiEQ knob –
controls the high frequency response (brightness) of the scanner.
•
QUALITY rotary switch
– offers the following scanner conFgurations:
◦
B3 –
modelled on the classic 16-position scanner,
◦
HiRes
– an original 48-position design, much smoother (especially when the scanner motor is
rotating at a low frequency, such as 1 Hz).
◦
SMOOTH
– softens the output of the scanner further by replacing the scanner with smooth,
continuous modulation.
•
TREM knob
– controls the amount of the tremolo effect in the scanner emulation.
•
C-MIX
knob
– controls the chorus mix – the ratio between the wet signal (i.e. processed through the
scanner) and the dry (unprocessed) signal. This setting has no effect in the Vibrato (V) modes.
INPUT
There are three knobs in the INPUT section.
•
GAIN knob –
controls the scanner input gain.
•
WIDTH knob –
sets the input width, values higher than 100% widen the stereo image of the input
signal.
•
DRIVE knob
– controls the non-linear behavior (saturation) of the scanner emulation.
OUTPUT
Similarly to the INPUT section, the OUTPUT section also features three knobs:
•
LPF knob
– sets the cutoff frequency of the low-pass Flter processing the output of the scanner.
•
WIDTH knob –
sets the stereo width of the output signal, values higher than 100% widen the stereo
image of the output signal.
•
GAIN knob
– controls the master output gain.
MODE SWITCH
This switch lets you select how individual rotation speeds and inertia parameters are expressed for the left and
the right channel.
•
L R mode
– the speed/inertia parameters for both channels are set as separate values (in Hz/seconds,
respectively [when the TEMPO SYNC switch is off, otherwise as note values]),
•
LINK mode
– the parameters are shown separately (like in the L R mode), but the ratio between them
remains constant (within possible range),
•
B D mode
– the parameters are shown in BASE DEV pairs consisting of a base value and the deviation,
applied to both channels, in opposite directions.
TEMPO SYNC SWITCH
Clicking on the TEMPO SYNC switch toggles the TEMPO SYNC mode. When the TEMPO SYNC mode is
enabled, the speeds and inertia parameters for both channels are expressed as note values ranging from a sixty-
fourth note triplet to a quadruple whole note. Note values are displayed as fractions with additional symbols,
e.g.:
•
1/2
– a half note,
•
1/4.
- a dotted quarter note,
•
1/8t
– an eighth note triplet,
•
1/16q
– a sixteenth note quintuplet,
•
1/32s
– a thirty-second note septuplet.
