Transistor Sounds Labs Stepper Acid Digitally Controlled Step Sequencer

Like most of you, i have been following this next project for a long time... but it's finally out now and the first ones have been shipped.

The Transistor Sounds Labs Stepper Acid is a 16-step Eurorack sequencer module designed by Nina Richards & Zoë Blade with live performance in mind.
The Stepper Acid was born out of our need for a modern step-sequencer.
The dual micro-controller design ensures tight timing: one runs the sequencer, the other the front panel interface.

It looks and sounds very impressive, and very easy to program... especially compared to a 303 ;-) ...

Doepfer A-147-2 Voltage Controlled Delayed LFO Announced

Doepfer recently announced the A-147-2, the successor of the VCLFO A-147.

This module but offers more features than the predecessor and is made of the following sub-units:

VCLFO: voltage controlled low frequency oscillator
VCA: voltage controlled amplifier, switchable to voltage controlled polarizer
VC delay unit: voltage controlled linear attack envelope (only one parameter: attack) for delayed LFO operation in combination with the VCA (e.g. delayed vibrato/tremolo)

"LFO: The voltage controlled LFO has the waveforms Triangle, Sine, Sawtooth and Rectangle available and features a Reset/Sync input. Triangle/Sine and Rectangle are displayed by means of dual-color LEDs (probably red/green), Sawtooth has a unicolor LED available (probably blue). 

The output levels are about -4V...+4V for Triangle, Sine and Rectangle. 

The Sawtooth level is about 0...+8V.
The CV control can be switched to attenuator or polarizer ("CV Mode" switch). 

In polarizer mode the CV inputs affects the frequency in the reverse manner when the CV control is left from the center position. In the center position CV has no effect and right from the center the control works like a normal attenuator. 

The frequency range (without external CV) is from about 0,005 Hz (i.e. about 3 minutes per periode) to 200 Hz. In addition a ultra-low mode can be activated by means of an internal jumper. 

When the ultra-low jumper is set a fixed voltage is connected to the switching contact of the "LFO CV" socket. In polarizer mode of the CV control that way extremely low frequencies (up to one hour period and more) are possible.

VCA: This is a linear VCA that can be switched to "normal" VCA (i.e. kind of a voltage controlled attenuator) or voltage controlled polarizer ("VCA Mode" switch). 

In the "normal" VCA mode amplification +1 is achieved with about +5V control voltage. 

In polarizer mode the amplification ranges from about -0.5 (i.e. inverted signal with about 50% level) with 0V CV to +0.5 (i.e. non-inverted signal with about 50% level) with +5V CV. With about +2.5V CV the signal is suppressed.

Details about the functioning of a voltage controlled polarizer can be found in the description of the module A-133. In this mode the VCA can be treated also a DC coupled ring modulator (similar to A-114).
The VCA of the A-147-2 has three sockets available: "In" (signal input), "Out" (signal output) and "CV" (control voltage input).
The Triangle Output of the LFO is normalled to the VCA signal input by means of the switching contact of the "VCA In" socket. If another LFO waveform (or any other signal) should be processed by the VCA the corresponding signal has to be patched to the "VCA In" socket. 

The VCA can be used also independently from the LFO and the Delay CV. 

In this case the VCA sockets In, Out and CV have to be patched accordingly. The VCA can be used also as waveshaper for the LFO signals (e.g. by patching VCA In and VCA CV to different LFO signals, if necessary via attenuator A-183-1 or offset generator/attenuator A-183-2).

A-147-2 block diagram

Attack/Delay: The third sub-unit of the module is a simple, voltage controlled envelope generator that has only the parameter "Delay" (or Attack) available. 

This unit generates a linear increasing voltage that starts from 0V after each Delay Reset until it reaches about +5V.
Then the voltage remains at +5V until the next Delay Reset occurs. 

The inclination or gradient is controlled by the manual Delay control and the Delay control voltage ("Delay CV" input). 

The waveform is linear, the control scale is exponential. The output voltage is displayed by a unicolor LED (probably orange) and available at the "Delay Out" socket.
The manual Delay control ranges - without external "Delay CV" - from about 5ms (fully CW) up to 2 minutes (fully CCW). By means of an external voltage applied to the "Delay CV" socket this range can be extended. A rising CV shortens the delay time (behaviour like a VCO) !
The Delay output voltage ranges from about 0V to +5V. The rising edge of the gate, clock or trigger signal applied to the "Delay Reset" sockets resets the Delay output voltage to 0 V.
"Delay Out" is normalled to the VCA CV input by means of the switching contact of the "VCA CV" socket and consequently controls the Triangle level provided that no other patch is made. 

A typical example is the usage of a Gate signal (e.g. from a USB/Midi-to-CV/Gate interface) as Delay Reset. 

That way a delayed vibrato or tremolo can be realized if the VCA output is patched to the frequency CV input of a VCO (or VCF), or the CV input of a VCA.
But the Delay sub-unit can be used also independently from the LFO and VCA, e.g. as a voltage controlled waveshaper or for other applications where a linear increasing signal with voltage controlled steepness is required."

The module is planned for early 2015, price ~ Euro 120.00, price and release date are still without obligation !

Random Video: Modular Synth Jam - Remedy Without Fear by Iteration and Discord

I like the latest upload by Iteration and Discord a lot... great sounds and build-up;

Video: Modular Synth Jam - Remedy Without Fear

" This patch started with the piston honda mk2. I wanted to use it as a noise source which became more of a snare drum. Next was tuning the tiptop dixie2 into a bass drum and using the doepfer bbd delay to make it interesting.
There are other parts courtesy of the tiptop 808 drums and the epoch modular benjolin. Nothing real complex here but it was definitely fun.

Also the make noise erbe verb played a big part in the beginning and also for making noise swells. All live, what you see is what you're hearing.
I'm using an analog mixer to bring parts in and out.
Thanks for watching and please check out my channel if you like modular synths.

I seek out synth related videos and watch as many as i have time for.
Please consider subscribing for more synthesized awesomeness."

The Benjolin Explained by The Tuesday Night Machines

Felix (The Tuesday Night Machines) uploaded a cool demo in which he explains Rob Hordijk's Benjolin module.

But first some info about the Benjolin, gathered from various sources;

" A darling of the DIY synth community for years now, Rob Hordijk's benjolin circuit is really like no other synth/noisemaker out there.

The Benjolin is the smaller sibling of Rob's now legendary Blippoo Box, the subject of his 2009 article in Leonardo Music Journal (Vol. 9). 

Both the Blippoo Box and the Benjolin emerged from Rob's attempts to design a circuit that was, as he puts it, "bent by design". 

 As such both modules function according to the basic principles of Chaos theory, where short to long sputtering patterns spontaneously alter themselves over time, at times gradually and at times quite suddenly, morphing into new pattern doublings and bifurcations. 

 The result is two incredibly unique instruments that function in a sense autonomously or can "play themselves" if you like.

Klangbau Koln Benjolin by Rob Hordijk

Both the Blippoo Box and the Benjolin are based around similar "chaotic cores," which in the the case of the benjolin, is comprised of two vcos and a unique circuit designed by Rob, which he calls a Rungler. 

 The Rungler is basically an 8 step shift register that takes its serial input from the squarewave of one oscillator and its clock input from the other. 

 The digital outputs of the shift register are than put through a primitive digital to analogue converter to create stepped voltage patterns, which are then wired back into the oscillators.

The effect of this arrangement is to create a complex interference pattern that gives the Benjolin its unique, aleatoric character."*

Rob Hordijk's Benjolin as a Eurorack module,(This version is made by made by Klangbau Köln) consists of two VCOs, a VCF, the famous "Rungler" and an audio mixer, which can mix the classic PWM sound with the dry VCO waveforms for added fatness. 

The VCOs can cross-modulate each other, VCO2's triangle wave can control the filter cutoff (if no external cutoff CV signal is plugged in) and the Rungler CV can of course modulate everything too. It's a complex instrument, which doesn't necessarily need any other modules to be enjoyed.

Outputs:
- Rungler CV
- OSC1 Triangle
- OSC1 Pulse
- OSC2 Triangle
- OSC2 Pulse
- Audio Mixer (VCO1 + VCO2 + PWM)
Inputs
- OSC1 Frequency CV
- OSC2 Frequency CV
- Filter Cutoff CV
A switch lets the Rungler run free, or locks its current pattern.

Chaos, noise, drones and sweet music, all from one device!

The Benjolin is an instrument designed by Rob Hordijk and built and modified by a lot of DIYers, as well as some synth manufacturers. I explain the Benjolin's basics with a Klangbau Köln Benjolin Eurorack module. Don't worry though, you will easily understand all other versions as well, after watching this video.
The cool thing about the Benjolin is, that it has some amazing feedback loops built in, which can be used to modulate the sound to the Moon and back ... well, some people say "to Hell and back" ... you decide. There is also the famous Rungler circuit of Rob Hordijk, which generates random, looping or evolving CV sequences via a shift register design (similar to the Turing Machine Eurorack module).
It's tons of fun!
