+#### DETUNE
+
+A 1V/octave pitch processor, for controlling a detuned oscillator pair.  A reference pitch in raised and lowered by the number of cents (hundredths of a semitone) specified by the knob and CV, and output at OUT+ and OUT-.  The input pitch is output at THRU.
+
 #### DGATE
 
 A triggerable gate with duration up to 10 seconds, with an optional pre-delay of up to 10 seconds.  A trigger pulse is output at END when a delay/gate cycle ends.  If the STOP/LOOP switch is set to LOOP, or if the trigger is high when the cycle ends, the cycle repeats.

 A dual sample-and-hold.  Sampling may be triggered by CV or button press.  If nothing is connected to an IN port, sampling for that channel is from an internal white noise source (range 0-10).
 
+#### STACK
+
+A 1V/octave pitch processor for stacking oscillators.  The SEMIS, OCTAVE and FINE knobs determine an interval (up or down) to apply to the input pitch and send to OUT.  The input pitch is sent unmodified to THRU, for ease of chaining multiple STACKs to control multiple oscillators, e.g. to create chords.
+
+The CV input expects +/-5 volts; the value modifies the interval set by the knobs in the amount of one semitone per tenth volt.  If QZ (quantize) is active, the CV-controlled interval is quantized to the nearest semitone.  This specialized CV is output at the THRU port, with a value set by the knobs and CV in, when there is no input pitch.
+
 #### SWITCH
 
 A signal-routing module with two through channels.  If the button is held or the GATE input is high, the HIGH input for each channel is routed to the corresponding OUT.  Otherwise, each LOW input is routed to each OUT.
