DEVIANT

Deviant bipolar pseudo-random voltage generator Eurorack module

 

IF YØU ARE LØØKING FØR A CLEAN STEPPED RANDØM STØP READING NØW. THIS MØDULE WAS DESIGNED WITH THE INTENTIØN ØF FØRCING ØTHER MØDULES TØ SØUND LIKE GARBAGE.

               When triggered, the Deviant øutputs a randøm vøltage between the ranges set by Tøp and Bøttøm knøbs respectively (-5v tø 5v). Bøth Tøp and Bøttøm have bipølar CV inputs, alløwing the user tø mødulate the windøw øf vøltages. Tø cøntinue in the Møffenzeef ethøs øf kraptastik electrønics, there is nøt a søphisticated DAC (digital tø analøg cønverter) øn the øutput øf the Deviant. Instead, a simple pulse-width mødulated løwpass filter is cøntrølled by the “Smøøth” knøb alløwing the user tø dial in the amøunt øf nøise, and the øverall slew øf the øutput.  The design relies heavily øn the gnarly søund øf the PWM (pulse width mødulatiøn) carrier frequency emitted frøm the brain øf the mødule which injects itself intø whatever yøu plug the Deviant intø. When plugged intø parameters expecting hard edges (a la Specimen øn GMØ) the Deviant will make the target glitch subtly which adds krispidy krunchidy klix n' pøps. If plugged intø an audiø rate søurce like a VCØ ør VCF, the carrier frequency gives the target a mild timbral shift reminiscent øf ring mød.

*This mødule pairs nicely with drum mødules where the user wants tø dial in subtle variatiøns in timbre upøn each triggering øf the drum.

Random is a loaded term and can be unwieldy and difficult to control. Moffenzeef Modular has created the Deviant, a dirty dual stepped random source Eurorack module that does most of the work for us. http://www.voltagecontrollab.com/2017/01/05/controlled-chaos-deviant/ Voltage Control Lab is the first school dedicated to Modular Synthesis, offering online courses and private instruction in Hardware and Software Synthesis and Sound Design.
This time, I'm experimenting with a condensed Modular On The Spot rig, with the Ornament & Crime running the 1.2 beta firmware which includes Sequin, a dual 4 stage 16 step sequencer app. Make Noise Tempi is the central clock. It's clocking the O&C in Sequin mode.

Here's a closer look at what the Deviant's output looks like. The "smooth" parameter slowly filters out the noise in the signal while adding slew to the output. With smooth all the way down the output is rather noisy giving parameters associated with timbre a mild ring mod-esque sound.
