Features and Notes

VC TimeGen Clock (TGC)

The VC TimeGen Clock has the left cell "blue" out being an asymmetrical tri wave & "red" out being a 50% duty cycle square wave output which stays constant through the manual "freq' POT range in combination with the "both" position selected w/ external CV -- BUT with the ability to modify the duty cycle (pulsewidth) of the output(s) using external CV source from either the front or the back of the pulse by selecting "rise" or "fall" on the CV source select switch. That way you can create syncopation in the rhythm patches & pulse width mod in the audio range use.

The right cell has DTG functionality, just like the CV TimeGen OSC.

Dual Comparator (COM)

The DUAL COMPARATOR (COM) provides several often useful house-keeping functions within the Serge system:

Logical Decisions: If the + input is greater than the - input, then the output will be high. If not, then the output will be low.
Level Detection. A pulse will be generated whenever an input voltage reaches a pre-set threshold. For example, when an envelope detector reaches a certain loudness level, it can be used with the Comparator to generate a pulse to activate or de-activate other events programmed within the synthesizer.
Voltage variable pulse width modulation of any of the Serge oscillators.
"Squaring" audio signals, whereby frequency related pulses are derived from an input signal. These pulses can be used for frequency sub-division (via a Dual Slope Generator or Sequencer), or as raw audio, rich in harmonic content.

In addition to the +/- inputs, each of the Comparators include a front-panel knob to manually set a threshold.

Pulse Divider (PDIV)

I think this is one of Rex's creations. Looks simple enough: feed a pulse train in, get multiple simultaneous divided outputs. Other pulse dividers I've seen from other manufacturers provide outputs that are powers of two (2,4,8,16...) but don't provide 5,6, or 7 or any odd-numbered divisors. Providing the odd divisors aids greatly in creating polyrythms.

Boolean Logic (BLOG)

This is the best way to combine triggers together in various ways. Of course, can be used for making audio too. One guy says he uses it as a blinky-lite indicator to show the status of signals in his system. This is one of Rex's ideas, offering two inverters, and OR, AND, and XOR gates.

Cross-Fader (XFAD)

The CROSS-FADER (XFAD) is an equal-power cross fade unit. The module has two signal inputs. As one signal increases in level at the output under manual or voltage control, the other signal decreases in level at the output. This effect is used to accurately fade one sound in while fading another out. Cross-fading with voltage control permits a smooth transformation between two different timbres. If a sound and its reverberated image (available with the Wilson Analog Delay) are sent through the cross-fader, the reverb mix can be voltage controlled. This effect can be used to modify the spatial characteristics of a sound event, from immediate presence to distant ambience. In addition to the cross-fade function, a VCA controls the output amplitude.
