OB 12 Z-Domain Synthesizer
8.7 EDIT LFO2
183
As for LFO1, LFO2 allows you to modulate the signal in the various generation sections of the
OB-12 with a low frequency signal. The main feature of the second low frequency oscillator is
that the quantity of modulation can be regulated by means of the [MODULATION] wheel on the
left of the keyboard.
From the EDIT TIMBRE MENU, select option 7 – EDIT LFO2. The display will show:
This video page contains the following programming parameters:
•
WAVE TYPE
([WAVE SELECT] of the LFO2 section)
: sets the waveform of the signal leaving LFO2.
The possible choices are:
SAW: sawtooth waveform;
TRIANGLE: triangular waveform;
SQUARE: square waveform;
RANDOM: waveform which assumes random levels;
•
RATE
([RATE] of the LFO2 section)
: regulates the frequency of the signal leaving LFO2 in a range
of values from 0 (minimum frequency) to 100 (maximum frequency).
If the DEPTH folder is now selected, the display will show the parameters for regulating the
quantity of modulation to be applied to the various sections:
•
DEPTH ON OSC 1
([DEPTH] with [DEPTH SELECT] on OSC 1)
: regulates the depth of the frequency
modulation by LFO2 on the signal leaving Osc. 1.
•
DEPTH ON OSC 2
([DEPTH] with [DEPTH SELECT] on OSC 2)
: regulates the depth of the frequency
modulation by LFO2 on the signal leaving Osc. 2.
•
DEPTH ON FILT.
(Depth on Filters, [DEPTH] with [DEPTH SELECT] on FILTERS)
: regulates the modulation
depth by LFO2 on the signal leaving the Filters section.
•
DEPTH ON AMP.
(Depth on Amplifier, [DEPTH] with [DEPTH SELECT] on AMPLIFIER)
: regulates the
depth of the width modulation by LFO2 on the signal leaving the Amplifier section.
If the LPF folder is now selected, the video will display the parameters relating to the low-pass
filter to be applied to the signal leaving the LFO2.
