- Right-clicking a mute buttons solos that channel (un-mutes that channel and temporarily mutes all others). Right or left click will un-solo, restoring the old state. Multiple channels can be "soloed" at once.
- The fader handles contain lights indicating the signal level out of that channel.
- - The Output saturates (soft clips) at +/-12 volts.

+WALK2 provides two channels of chaotic output, where the output voltage moves as a random walk. The two outputs are drawn as a trace, in X and Y, on the display. It may also be configured as an X/Y controller.
For each channel:
- RATE (knob and cv) controls how sedately, or wildly, the CV moves around. If CV is in use, it is attenuated by the knob.
- OFFSET (knob and cv) 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 (knob and cv) attenuates 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, derived from X and Y channel outputs.
+DIST outputs a third CV, ranging over 0-10V, derived from 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).
+The TRIG input can be set to one of three actions by the TRIG selector below it:
+ - JUMP: on each trigger at TRIG, both channels will jump to a random value.
+ - S&H: on each trigger at TRIG, the value of the random generator on each channel is sampled and held.
+ - T&H: while there is a high gate voltage at TRIG, the random generator output is passed to each channel's output; when the gate drops, the last value is held.
+
+The display can be interacted with directly:
+ - A click on the display will jump the outputs to the corresponding value.
+ - Clicking and dragging will force the outputs to track the mouse.
+Using these in combination with the S&H mode, where the values will hold until something changes them, makes WALK2 to into a handy X/Y controller.
+
+All discontinuous output jumps, caused by any of these means, are subject to a small amount of slew limitation, to avoid pops.
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).
