NOISE SOURCE
The NOISE SOURCE has a single output jack. It delivers a waveform that is completely
random. When you listen to this waveform directly, you will hear a steady pitchless
"white noise" sound. When you apply the waveform as a control voltage, you will hear
the resultant sound become rough and "static-y".
Temporarily connect the NOISE jack directly to the input of your audio monitor. Note
the distinctive "white noise" quality of the waveform. (NOTE: You can use this waveform
as the audio input of an effects processor such as a moogerfooger MF101 Lowpass
Filter.)
• Connect patch cords as follows:
a) from the NOISE jack to an ATTENUATOR IN jack,
b) from the ATTENUATOR OUT jack to your VCTG pitch control input.
Note that the pitch becomes rough and jagged. The amount of roughness is
determined by the setting of the ATTENUATOR knob.

SAMPLE AND HOLD
The SAMPLE AND HOLD module has two inputs and two outputs. The two inputs are
labeled IN and TRIG. Whenever the TRIG signal crosses a preset threshold, the voltage
at the IN jack is sampled, and is held until the next time the TRIG signal crosses the
threshold. The sampled voltage appears at the OUT 1 jack. In addition, the OUT 1 signal
is fed through a special lowpass filter which smooths the signal out and then delivers it
to the OUT 2 jack. The cutoff frequency of the special lowpass filter is directly related to
