A = X when Y exceeds 1V
B = noise ±8V
Z is slew rate
Parameter Min Max Default Description
0 0 1 0 Mode.
1 0 31 0 Offset.
2 0 3 1 Noise colour.
3 0 64 0 Noise X.
4 0 32 32 Atten B.
5 -1 31 -1 Up slew.
6 -1 31 -1 Down slew.
If parameter 0 is 0 (the default):
Output A is a sample of input X, taken when the trigger input Y goes over 1V. (Sample and Hold)
If parameter 0 is 1:
Output A follows input X while input Y is over 1V. When Y falls below 0.5V, output A is held
until Y goes over 1V again. (Track and Hold)
Output B is a noise signal. Noise is commonly fed into the input of a sample and hold device to
generate clocked random voltages. The amplitude of output B is set by parameter 4; the maximum
is ±8V.
Parameter 2 controls the noise colour:
Parameter value Noise colour
0 Violet
1 White
2 Pink
3 Red
The Z knob/CV controls the slew rate of output A. At the minimum value of Z, changes in A are
instantaneous. As Z increases, changes in A take place more slowly.
Parameters 5 & 6 allow you to specify different slew rates when the signal rises or falls. If the
parameter is -1, the slew time is set from Z; otherwise the slew is set from the parameter value.
Pressing the Z knob triggers a sample manually.
Parameter 1 sets an offset between the timing of the X & Y inputs (in sample frames). If X & Y are
being driven together, for example by a sequencer's pitch and gate, it is often a good idea to delay
the trigger slightly to allow time for the sampled CV to settle before the sample is taken.
Parameter 3 adds the noise output into the input signal, equivalent to patching output B into input X
via an attenuator.
