Controlling the LFO frequency
The LFO frequency is controlled by a potentiometer connected to the terminals LFO POT
CCW, LFO POT CENT and LFO POT CW of JP3:
Another type of LFO control is the usage of separate controls for the rising and falling slope.
In this case the wiring of the LFO pins is a bit different:
In this case the terminal LFO POT CCW is unused.
It is also possible to switch between both version of LFO control by adding a switch between
the terminal LFO POT CENT and the two circuits.
