POLARITY
Switch to set the polarity for envelope1:
If the switch is on the top, the envelope polarity is positive (this is
the more common way to use an envelope).
If the switch is on the bottom, the polarity is negative. The
envelope’s time settings are reversed: the shorter times will be
heard when the faders are on their higher positions.
This type of polarity is very nice to create some inverted effects.
Take a look on the preset “Original JP-8 Preset / EFX /JP-
8_66_Fact” to hear an example of this special effect.
7.1.6 The LFO
Using the LFO as a modulation source is very common. It can be used to create a vibrato
effect (when the LFO modulates the frequency of an oscillator) or a “wah-wah” effect
(when it modulates the cutoff frequency of the filter).
RATE
Knob to set the speed of the LFO
DELAY TIME
Knob to set the delay time before the LFO becomes active
WAVEFORM
Switch the LFO’s waveform:
Sine
Saw tooth
Square
Random
The LFO
7.1.7 The VCO modulator
The VCO modulator section allows adding modulations to both of the oscillators’
frequencies (for vibrato or automatic pitch bending effects) and on the pulse width of
their waveforms.
Frequency modulation
LFO
Slider to set the level of modulation from LFO on the VCO frequencies.
ENV1
Slider to set the level of modulation from Envelope 1 on the VCO
frequencies.
VCO 1
VCO 2
Selector to choose either oscillator 1, oscillator 2 or both oscillators as
destinations for LFO / ENV modulation.
PWM
Slider to set the level of modulation on the VCOs’ pulse width.
