Cascaded Frequency Dividers
Also known as flip/flop or sub-octave processor, each of these changes its logic state each time a low to high transition is performed. Sections are semi-normalled in order to achieve 1/2 and 1/4 outputs from a single input. Output range switches are useful to obtain unipolar (0V/+10V) or bipolar signals (-5V/+5V).
When an audio signal is used it works as a sub-octave generator (square/pulse preferred). When a clock is used it works as a clock divider. Random clocks from SAPÈL create interesting variable-length sequences of gates.
Four Quadrant Multiplier
Also known as ring modulator, balanced modulator, or ThruZero VCA, this sections precisely multiplies two signals, making any sort of amplitude/loudness modulation possible.
With an exceptional linearity, and a bandwidth from DC to more than 20KHz, the result of this operation is completely up to the sources in use: from a simple dual unipolar multiplication (one quadrant), to unipolar / bipolar (two quadrants), up to any kind of dual bipolar multiplication (four quadrants).
The two inlets are semi-normalled to yellow and green generators. The 4 led matrix shows which of the quadrant is currently in use.
It may also be used as a VCA, with linear CV response.
Linear Slew Limiter
Also known as portamento/glide when using a pitched CV, this processor comes into play when any voltage smoothing is needed. With independent rise and fall slew rates, it is possible to precisely smooth any kind of voltage transition.
