+### <a name="random"></a> Noise/Random, Sample and Hold
+
+
+
+#### NOISE
+
+A noise source, in types blue (f), white, pink (1/f), red (aka rown, 1/f^2) and Gauss (normal with mean 0 and variance 1).
+
+Additionally, NOISE has an absolute value circuit. Patch audio into ABS to get positive CV. For example, patch white noise into ABS to get uniform values in the range 0 to 10.
+
+#### S&H
+
+A dual sample-and-hold and trigger-and-hold. Sampling may be triggered by CV (on the rising edge of a trigger or gate) or button press. If nothing is connected to an IN port, sampling for that channel is from an internal white noise source (range 0-10V).
+
+Each channel can be toggled into track-and-hold mode. In this mode, when the input at GATE is high, or the button is held, the input is copied to the output. When the gate goes low, the input is sampled and held until the next gate.
+
+#### WALK2
+
+WALK2 provides two channels of chaotic CV, where the CV moves as a "random walk". The two outputs are drawn as a trace, in X and Y, on the display.
+
+For each channel:
+ - RATE controls how sedately, or wildly, the CV moves around. If CV is in use, it is attenuated by the knob.
+ - OFFSET adds or subtracts up to 5V from the base +/-5V output. If the offset CV is in use, it is attenuverted by the knob.
+ - SCALE scales the output; if CV is in use, it is attenuated by the knob.
+
+Additionally:
+ - A trigger on the JUMP input will cause both channels to jump to a random value. A bit of slew limitation applies to the jump to minimize popping.
+ - DIST outputs a third CV, ranging over 0-10V, related the X and Y channel outputs.
+
+Clicking on the display will jump the outputs, X and Y, to that point (again with a bit of slew limitation).
+
+Various options on the context (right-click) menu allow customization of the display (set the range of the display to +/-10V instead of the default +/-5V; hide the grid dots; set the color of the trace).
+
+#### WALK
+
+WALK is a single-channel random walk, identical to one channel of WALK2, in 3HP.

-Additionally, NOISE has an absolute value circuit. Patch audio into ABS to get positive CV. For example, patch white noise into ABS to get uniform values in the range 0 to 10.
-
#### OFFSET
An offset and scaler. The OFFSET and SCALE knobs have CV inputs. With an input signal, output is `(input + offset) * scale`. With no input connected, the output is constant in the value of `offset * scale`.
By default, the output is capped at +/-12 volts (this is a standard in Rack). A context menu option allows this limit to be disabled.

A slew limiter - when the input changes rapidly, the output changes less rapidly, lagging the input.
