+The context menu option "DC offset correction", on by default, removes DC offset from the outputs. Presently, this only affects the square output when the pulse width is set to anything besides 50%. When this is enabled, and viewing the output on a scope, the waveform will move up and down relative to 0V as the pulse width is changed -- this is the DC offset removal in action. When disabled, the waveform stays centered on 0V, which is useful if using the output as CV.

As a multiplexer, it routes an input to the output under control of the SELECT knob and CV. A -10-10V CV, divided into 16 equal divisions of 1.25V, controls the input selection. A CV between +/-1.25V does nothing; a voltage of 1.25-2.49V will add 1 step to the selection, a voltage between -1.25V and -2.49V will subtract one step, and so on. This value is summed with the knob setting; for example, setting the knob to 4 and inputting a 2.6V CV will send input 6 to the output. When the knob-plus-CV value exceeds 8, it wraps around.

A window function is optionally applied to the signals as they are converted to the frequency domain; this cleans up noise that otherwise shows up in the signal plots as an artifact of the conversion. It also slightly distorts the displayed signals. The default "taper" window minimizes the distortion; Hamming and Kaiser windows are also available. The window can be selected or disabled on the context menu. The window is not applied to the test signal before it is emitted at SEND.
-The test signal is a swept sine wave (or "chirp", see <a href="#chirp">CHIRP</a>), with an exponential (if the EXP toggle is on) or linear sweep. The start and end frequencies for sine sweep are set by the FREQ1 and FREQ2 knobs, each with a range in hertz from 1 to a bit less than the Nyquist rate (half the sampling rate); if FREQ1 is less than FREQ2 the sweep is upwards in frequency, downwards otherwise.

Patching an input to TEST overrides the swept sine generator; the TEST input is used as the test signal.
If the LOOP toggle is enabled, the module continuously outputs, collects and displays the test, response and analysis signals. Regardless of whether the collection cycle is triggered or looped, a pulse is emitted at the TRIG output when the cycle begins, and at the EOC output when it ends.
-The R. DELAY (response delay) control allows sample-accurate alignment of the test and response signals for analysis. When SEND is patched directly to the module to be analyzed, and that module's output is patched directly back to RETURN, and the analyzed module does not impose an internal sample delay, then the returned signal will be received by RANALYZER two samples later, relative to the test sample RANALYZER emits. More complicated patches between SEND and RETURN, or modules under test which have internal sample delays, can increase this, in which case R. DELAY may be set to whatever this actual sample delay is. In practice, getting this right will likely not be very important.

+CVD may be used for lag/latency correction; using parameter entry (by right-clicking the TIME knob) is handy here, to set a precise delay. You can get sample-accurate delays by dividing the desired number of delay samples by Rack's current sample rate, and setting TIME to that number (leave the time scale knob at 1).

+
+LGSW is a version of <a href="#switch">SWITCH</a> with two gate inputs and onboard logic.
+
+If nothing is patched to either of the gate inputs, or if just one is patched (either one), the behavior of the module is identical to SWITCH (the logic section has no effect).
+
+If both gate inputs are in use, then the logic will evaluate to true according to the gate states and the logic mode:
+ - OR: true if either gate is high.
+ - AND: true if both gates are high.
+ - XOR: true if exactly one of the gates is high.
+ - NOR: true if neither of the gates is high.
+ - NAND: true if both gates are low.
+
+When LATCH is off, and both gates are in use, the module outputs the HIGH input whenever the logic is true or the button is held.
+
+When LATCH is on, and both gates are in use, the latch will toggle when the logic state changes, or when the button is pressed.
+
+The logic mode can be set by CV. Using a CV for the logic overrides whatever selection was made with the small mode-select button. A O-5V CV will select the mode as:
+ - OR: less than 1V.
+ - AND: 1V but less than 2V.
+ - XOR: 2V but less than 3V.
+ - NOR: 3V but less than 4V.
+ - NAND: 4V or more.
+
+_Polyphony:_ Same as <a href="#switch">SWITCH</a>, except that the polyphony channel count is set by the topmost gate input only.
