Scanner

SCANNER takes a 0-5V input voltage and turns it into 4 0-5V overlapping triangular output voltages. A classic "weirder to type about than in practice" module. Scanner is useful for driving VCAs (for a 2-4 way crossfade), waveshaping (any input wave comes out a triangle), and probably lots more!

CMP

Karltron

CMP is a utility module in 6HP, simply comparing two voltages. Dual channel. It performs the logic operation A>B=C in a unipolar fashion, thus giving about 0-11V outputs. B is normalled to +12V, and run through the attenuator knob, so you can use just A and the knob sets a threshold voltage where the output goes high.

Clock

Free Modular

A basic, 8-channel clock source with adjustable tempo, phase shift, pulse width, and swing.

Manual

Clock Multiplier

Bumm Bumm Garage

"I’ve heard, especially with Lady Starlight, that techno tracks get more interesting when the bassline hits in triplets (3 beats), quintuplets (5 beats) or septuplets (7 beats). In contrast, the songs from my techno rack have always been relatively linear in this respect. That’s why I build this Clock Multiplier. The main inspiration is Befaco’s Burst, from which I took the terminology for quantity and distribution."

POL

Seismic Industries

"attenuate, invert, amplify. all voltage controlled and nicely visualized"

Documentation

A marvelous design but very compact construction .. take your time in assembly.

Rect-Reco

Barton Musical Circuits

"This module rectifies an input's positive and negative voltages and outputs them to separate jacks so they can be processed separately. The signals can then be returned and mixed back together in the re-combiner section. The re-combiner's inputs have their own rectifiers built into them so it can also be used to mix together different signals while preserving the polarity difference."
