QuBit Electronix Nano Rand

QuBit

Nano Rand
Qu-Bit Electronix has published more info and a video about their latest module, the Nano Rand.

"Nano Rand is a sample and hold, noise source, and random voltage generator in 4 HP.
It takes inspiration from and improves upon the analog concept of a random voltage module; moving forward in leaps and bounds into the digital domain.
At its­ core is an 8 bit microcontroller which allows for an extremely versatile, and more importantly, musical type of random.

- 4 switchable random voltage algorithms
- Can be internally or externally clocked
- Random gate source that generates musical derivatives of incoming clock
- Generates random frequency audio rate square waves allowing it to be both audio and control source
- Random voltage can be unipolar or bipolar

Specifications:
Width: 4hp
38.1mm (Skiff friendly)
Power: 60mA
Price: $190.00"

MakeNoise Richter Wogglebug Update

MakeNoise gave their Richter Wogglebug a nice update.
"The "WoggleBug" is a random voltage generator, originally designed by Grant Richter of Wiard Synthesizers.

Richter Wogglebug Re-design
It is a continuation of the "smooth" and "stepped" fluctuating random voltage sources pioneered by Don Buchla within the Model 265 "Source of Uncertainty," expanding it to include the other-worldly Woggle CVs (stepped voltages with decaying sinusoids edges). 
The Wogglebug is a very musical random voltage generator where it is possible to synchronize all random signal to a Master Clock. 
Guaranteed to unleash your synthesizer's ID MONSTER!

The Wogglebug features ( check out the new features below the video):
- Complete Complex Random Voltage system, no external modules necessary
- Two VCOs, Phase Lock Loop, Lag Processor, Clock, Burst Generator and Sample & Hold
- Generates 7 Random Signals simultaneously: Smooth VCO, Woggle VCO, Ring Mod, Stepped, Smooth, Woggle, Burst
- Generates ultra stable, voltage controlled Master Clock
- External inputs for S&H (Heart IN) and Ring-Mod (Influence)
- Disturb button adds performance element
- Wonderful for modulating the Phonogene and DPO

" The Wogglebug is a random voltage generator, originally designed by Grant Richter of Wiard Synthesizers. It is a continuation of the "smooth" and "stepped" fluctuating random voltage sources pioneered by Don Buchla within the Model 266 "Source of Uncertainty."
New features in the Richter Wogglebug:

- A much more stable clock output with the widest frequency range yet seen on a Wogglebug. The clock now goes up to about 200Hz, allowing the Control Voltage and Gate OUTputs to be heard directly as different flavors of analog and digital noise.
- In previous Wogglebugs, the clock had been locked to the internal Sample and Hold Circuit. Now, with the Richter Wogglebug, the clock can be freed by the independent External Clock INput or the Disturb Button. Regardless of what is happening at these control points, the Internal Clock OUTput will continue to run at the specified rate, keeping it open for use as a Master Clock at all times.
- The Disturb Button allows the Sample and Hold Circuit to be clocked manually: press to sample, release to hold. When the Wogglebug is running fast, this can slow it down. When running slow or not at all, this kicks it in the ass and delivers the next set of random values.
- The Smooth VCO is a brand new waveform, Sharktooth.
- The Influence input has a greater effect on all parts of the Wogglebug's psyche than the previous Ring Mod input.
- The Burst output is more active and ALL portions of the Wogglebug are more responsive to control and touch."

Slow Nova Modules Probably

SlowNova Probably
Slow Nova Modules is a small company from Boston that sells hand built Eurorack modules and kits.
Today they published the first proper build of their latest module with the new face-plates on Twitter.

The Probably module is a dual 2 to 1 analog multiplexer with probability based switching.On each clock a random number decides which input is connected to the output. The likelihood can be set independently for each switch.

Inputs:
A, B, C, D - -12V to 12V
Clock - 0 to 10V
Outputs:
A/B - -12V to 12V
C/D - -12V to 12V

Switching Time - 75ns
Current Draw - 14.5ma

The module will be on sale soon for 150 USD,
(i believe it is already sold out though)

Using an A-118 to Liven Up A Bassline (Look, No Hands)

One of the main problems that I have when performing live with a modular synth is that i only have two hands.
This new PatchPourri post shows an example how to simply  'automate' a filter with an A-118 Noise/Random Voltage module.
This can add a nice random effect to your basslines, with the right settings, and might be useful in live situations where you can't pay attention to everything.

I don't use the Noise audio-outputs of the A-118 Noise/Random Voltages a lot, but i love using the random outputs of this module.
(I even added a 2nd Random output to this module a few weeks ago - find my blog-post about it HERE)

The patch goes as follows;
A sequence on the MAQ16/3 controls an A-111 VCO sawtooth that goes into an A-121 Multimode filter
A-118 RND output controls the Filter cutoff, the other (copied) A-118 RND output controls the Resonance.
I added an envelope to the A-121 CV2-input to make it a little bit more punchy.

No edits or effects... no hands (just watch the LEDs on the A-118)
All hands were free for simple additional drums from my Machinedrum.

Equipment used: Doepfer A-100 system,A-118 Noise/RND Voltage and A-121 Multimode BandPass filter plus Roland R8 and Machinedrum"

This principle was also (maybe even better) used in one of my earlier A-120 videos, just keep your eye on the yellow wire.

Doepfer A-118 Extra Random Output Modification

A-118 front panel,
secured and ready
for drilling
In preparation for the next #ModularBattle round, i figured out i had to do something to get a little bit more out of my pretty basic set of Doepfer Modules.

I decided to add an extra Random Output to my A-118 Noise/Random Voltage module, which was quite an easy job.

After i removed the knobs and the sockets i could remove the frontpanel of the module.
I mounted it on a flat piece of (old)wood, and secured it with two nails to avoid the frontpanel slipping away.
With a nail and a hammer i punched a small guide-hole for my drill, and drilled an extra hole for the new mini-jack connector.

To protect the front-plate, you can use an adhesive foil or (painter's) masking tape to cover the front, but if you drill very carefully, and don't wipe but blow the aluminium-scrapes off the module you'll be fine.

A-118 extra random output wiring
The new mini-jack connector was one that i ordered from Doepfer earlier (i have a big collection of mini-jack connectors, knobs and switches - they sell them seperately as spare parts) and the connection with the other random output was made with 2 pieces of wire and my soldering-iron.
The connection was as easy as it looks, and it looks like my soldering-skills are (slightly) improving...

Finished module with
extra random output
Don'be afraid for any CV-loss now that the signal has to be distributed over the two Random busses.
Doepfer confirmed to me that "this just works as a mini multiple and doesn't lower the CV"

Now that the modification is done, the module sends 2 similar (controllable) random voltages to both outputs that i can use for all kinds of purposes throughout my modular synthesizer.

For a modification that was done in less than an hour, it is a nice improvement...

The mods described on this site will most likely void any warranty and, if not done carefully, can damage the circuit board, IC chips, and faceplates.
