=== Sample & Hold Function ===
In new versions the modulation input of '''LF-VCO C''' has a S&H right after the input connector, but just before the input level knob. '''LF-VCO C''' triggers the S&H circuit.
 
The S/H is triggered every change of direction (rising to falling, or falling to rising)
 
On every positive peak and on every negative peak of the triangle waveform the S&H samples the '''LF-VCO C''' modulation input signal and holds the sampled value during the slope that follows. This means that the S&H causes every up-slope and every down-slope of the triangle to have a different duration, defined by the momentary value the S&H happened to sample. The slopes remain perfectly linear, only their steepness is affected. The effect is that there is a more or less random spread in time. This also effects the duration or width of the pulse output.
