Flux is a glitchy/jerky low frequency* random CV source created with extreme low pass filtered analog white noise.

Two bipolar LEDs give some insight into what the module is doing at any given time. The bottom LED will turn blue when the CV is positive and red when negative. The top LED will match that color code but only comes on when the CV amplitude is 2 volts or greater.

The offset control is very sensitive and will give the random CV a positive or negative bias. It is possible to over offset the CV and have a tweaky +/- DC source.

There is a 1-3 minute “warm up” period before the circuit stabilizes and reaches equilibrium. Until then the random output will have a negative bias and white noise will not be heard and/or centered around ground.

*true random stuff doesn’t actually have a frequency because it doesn’t repeat

Outputs:

  • RAW – AMPLIFIED WHITE NOISE OUTPUT – USUALLY NORMALIZED AROUND +/-8 VOLTS (MAY HAVE A SLIGHT POSITIVE DC BIAS, NOT USUALLY AN ISSUE AT ALL FOR AUDIO SORCES, ESPECIALLY NOISE)
  • RAN (RANDOM) – SUBAUDIO CONTROL VOLTAGE OUT +/- 8ISH

This thing is simple and greatReview by E
This is exactly the kind of random modulation that made me want to get into eurorack. It's simple and goes from subtle to moderate - no real over-the-top modulation, which is fine. The offset is great for dialing in a sweet spot between + or - or for favoring one pole over the other. The depth is like having an attenuator on the output, which is handy for going into modules that don't have attenuators on their inputs (Clouds for example). The "raw" white noise output is a nice bonus and a different sounding noise than I'm getting elsewhere in my system.

I had one question about assembly, which I emailed Noise Reap about and got a reply literally within minutes. (There are only 2 holes on the pcb for a 3 pin transistor - Cody replied and told me to cut the collector pin as close to the body as possible and install the other 2 pins.)

The parts were easy enough to source, though I ordered incorrect pots cause I wasn't paying attention (16mm "pc mount" from Tayda fit the bill - never used those before).

I'm having fun multing the "ran" out, inverting a copy, and sending the normal signal to one VCA and the inverted to another VCA, then taking their outputs to a mixer and panning one left and one right for some bubbling random pan.

It's a great module and a great value. I imagine I'll be getting some more Noise Reap modules. (Posted on 11/22/2016)
