Applications
The Auxiliary LFO is a versatile modulation source.
Main LFO Modulation Source
The natural use of the Auxiliary LFO is to provide frequency modulation for the Main
LFO. This is made through the optional internal normalising from the Auxiliary sine
wave output to the Main CV input. The Shape control then comes into play to vary
the profile of the frequency modulation of the Main LFO, with dramatic full sweeps
with the Shape control at either extreme.
Externally Synchronising The Auxiliary LFO
One significant difference between the Main and Auxiliary LFOs is the Sync input. Put
simply, the Sync input synchronises the Auxiliary LFO to an external trigger or clock
signal. It is switchable between positive and negative edge sensitivity. When
triggered, the Sync input forces the Auxiliary LFO to the start of its cycle (0 degrees).
This is defined as being an output of 0 volts, and rising.
The oscillograph on the next page shows the Auxiliary LFO sine wave output (top)
being synchronised to the rising edge of an external square wave (bottom). The trian-
gle output will follow a similar path, but with straight lines instead of the graceful
curves of the sine.
