26. ther is for the clock trigger What happens in a S H is that when it detects a voltage signal at its sampling input it holds it for the duration of the clock pulse It doesn t matter if the sampled voltage fluctuates at all during one clock pulse s cycle the output will remain constant until a new clock pulse is received whereupon the output will change in accordance with the sampled voltage This way stepped voltage changes can be created from smoothly changing inputs from EGs or LFOs When used with a noise source random changes can be created Obtaining a stepped random signal using the Sample and Hold Facility To create a stepped random voltage Patch a square wave LFO output into the S H Clock input the Noise output to the S H Signal input Turn the Noise level up The S H output signal will appear at the S H Out socket Controls In Detail S H Slew This adds slew or portamento between each changing voltage held by the S H So as each voltage is sampled the changes in old to new voltage level will be smoothed out Noise Level Alters the noise level Sockets In Detail S H In This is the signal source for the S H Normally the noise output would be used for a random output S H Clock In Each clock or gate pulse will make the S H sample the input signal then hold it till the next clock signal Normally a square wave signal would be fed into here like LFO1 2 square wave output S H Sig Out This is the output from t
