Special Flexi-Only Modulation Sources

There are eight modulation sources in the list which can only be used with Flexi Controllers -
they are not found elsewhere in the Editor. Six are LFOs and two are noise sources. They
are explained below.
● VCO3/VCO4 LFO (TRI/SQR/SAW):
Each of these two LFOs has three waveforms - saw, square and triangle. To
conserve precious space in the Editor, some sharing of sliders has become
necessary: the LFOs' frequencies and pulse widths are adjusted by using the LFO
FRQ and OFFSET sliders from the PULSE WIDTH sections of VCO3 and VCO4.
Note that moving any of these four sliders will result in both parameters assigned to it
being adjusted simultaneously.
In order to have many different applications using a broad range of frequencies,
VCO3 LFO is four times faster than VCO4 LFO.
Tables in the Appendix for details of the actual frequencies).
VCO3 LFO is free-running, whereas VCO4 LFO is synchronized to the trigger event:
whenever you play a new note, the phase of VCO4 LFO will be reset.
Note: The PULSE WIDTH OFFSET behaves differently than might otherwise be
expected when used to control the pulse width of the VCO3/VCO4 LFOs. Ordinarily,
when PULSE WIDTH OFFSET is used to control the square waves of the VCOs, the
waveform is symmetrical at 0 and is a narrow pulse at 127. By contrast, when
PULSE WIDTH OFFSET is used to control the pulse width of the VCO3/VCO4 LFOs,
it is symmetrical (50% duty cycle) at 64; settings of 0 and 127 equate to duty cycles
of approximately 10% and 90% respectively. See the diagram below:
