Serge’s 1979 ÷NCOM - It Compares, Counts, Waits, Fires and It Always Rises

video upload by Cinematic Laboratory

"I bought the #Serge #NCOM in the blind because a) it's the work of a living legend, b) I had no idea what it did, and c) after reading the manual and looking on YouTube I still had no idea how to use it in real life music.

The ÷NCOM is short for pulse divider (by N steps), a comparator (gate goes high where +IN is higher than -IN) and last but not least, a staircase CV is raised one semitone when the compare goes high and the max steps N is not reached. So now you know, and just like me, it still remains a mystery how it can play a role in modular music.

÷NCOM is from 1979, and quantized CV was rare, especially when it's derived from any two compared voltages. It's using two CMOS chips, but only 5 of 8 bits were used (step 0 to 31 = 32 values). So is it early digital? Yes, but without a CPU or code and state of the art precision - for 1979. Is it still relevant in 2025? I am not sure how many voltage comparators are around in eurorack, and you probably never needed one. A staircase CV waveform is simply a matter of running a ramp through a quantizer, and you may be able to use an END of RAMP event on a Maths clone. The ÷NCOM circuit is often used for rhythmic patches, and the staircase is super useful to make synchronized ramps you can use to open a filter or wavefolder. Not to mention arpeggios. It's the opposite of high-tech, it's low tech. A circuit you need to learn, discover and find use for. It was special in 1979, and today it's part of the joy of owning a true Serge module that can always do more than you think."

Tone Science Module No.10 The Final Patch (DiN:TS10)

"Now available as a double CD with an 8-page booklet & download

Tone Science sub-label, from DiN records, concludes it’s exploration of the world of modular synth music.

Since the first volume in the Tone Science series was released in 2018, seventy-two musicians in total have joined in with this celebration of the musical possibilities of modular synthesis. These artists have been from a huge range of backgrounds but have all shared the unifying purpose of showcasing the incredible variety of sonic possibilities these instruments can offer.

Tone Science sub-label, from DiN records, concludes its exploration of the world of modular synth music.

Since the first volume in the Tone Science series was released in 2018, seventy-two musicians in total have joined in with this celebration of the musical possibilities of modular synthesis. These artists have been from a huge range of backgrounds but have all shared the unifying purpose of showcasing the incredible variety of sonic possibilities these instruments can offer.

The intervening seven years have seen the modular synth world expanding at an exponential rate and whilst one wouldn’t go so far as to say these synths are mainstream, they are certainly far more prevalent than in the past. It’s especially gratifying to see so many musicians now either play solo sets with them or to include them in their onstage arsenal.

Thus we come to this, the final instalment in the Tone Science series. Nothing lasts forever and certainly stopping at this nice round number of ten seems like a good way to not only end the series but to release the Final Patch, a real celebration of what has gone before and perhaps to hint at what is possible for the future. A beautifully packaged double CD featuring twenty artists who have appeared on previous iterations of the series, it really is a who’s who of modular synth musicians. The release is accompanied by an eight-page booklet with an essay by Neil Mason and some final words from the guiding force behind the whole project, Ian Boddy, label boss at DiN. And as Boddy so succinctly puts it in his liner notes, “for me, despite the technological nature of the equipment, the emotional quality of the music is the single most important factor”. The Final Patch certainly delivers on that ethos.

1:00:15 closing thoughts



Boundary Layer is a triple cycling slew acting as a powerhouse of modulation, audio
mayhem, and obscure modular tricks. Each of the channels can act individually as:
-a modulation oscillator
-voltage controlled slew (including portamento)
-AR/AD envelope (decay or release determined by choice of input).

All three channels are tied together by three global inputs, as well as three outputs which select the MAX, MID, and MIN of all three voltages. Using different combinations at audio rate allows for patch programmable stereo drone synth capabilities.

Features

3 separate channels
3 global inputs
3 combined outputs MAX/MID/MIN
Oscillates from low LFO rate (a minute?) to audio rate (>10kHz with exponential feedback)
A CV input switchable between RISE/FALL/BOTH
Bound input for simultaneous control over cycling rate and amplitude
TRIG input for AD envelopes
SLEW input for AR envelopes and portamento or filtering
EOC ouput header switchable between EOR and EOF
16 HP
Skiff friendly 32mm depth (including cable)
current draw: +12V 170mA, -12V 100mA

Background Modulars No.11 Serge Paperface Again

video upload by Memetune Studio

"Don’t have a real Serge Modular Paperface to hand? No worries! Just put this video on in the background (in full-screen mode), and have the next best thing 😁

Here is 10 minutes of self-playing modular synthesiser randomness. Why not put it on loop - then you can have it playing away in the background while you do other things

A note on the patch: I'm using the LW Gated Comparator and the 2 original Paperface Sequencers (from the mid-70s) to run things - as always with a big Serge patch its virtually impossible to keep track of all the connections - its a very complex system - but I use lots of delays here - the vintage Wilson, plus a brand new Prism Circuits Cascade Delay. There are the old Serge dual spring reverbs in here, and the VC stereo mixer to mix it all up and move it all around. This patch is more melodic, using a Serge format Voltage Quantizer to hold it all together. It's going through my Neve 88D along with some vintage FX units - an AMS RMX16, a Bel BD80S and a Lexicon Model 300"

Crossing the threshold: New Systems Instruments’ “discrete map”

video upload by Electrum Modular

"New Systems Instruments sent me their new module, Discrete Map. It’s a deep module, with lots of potential uses, so I’ll be dedicating the next few videos to it. This first, introductory video uses it as a generative sequencer, extracting an evolving melody from a Lorenz chaos trajectory."

"Novum! New Systems Instruments has created a unique and innovative approach to generating sequences with Discrete Map.

New Systems Instruments consistently surprises with innovative designs! Discrete Map fits right in, taking a simple concept and turning it on its head. At its core, it’s an 8-step sequencer that can output a traditional step-by-step sequence. The pitch values are set using the eight upper faders, but what makes it truly special are the eight lower faders, which determine which step is played at any given moment.

The sequencer’s X input accepts any signal, a clock, an LFO, or even another sequence. The lower faders set threshold values, and the switches below them define whether they react to a rising or falling edge. This means the sequence jumps to different steps based on the incoming signal, creating a highly controllable form of randomness! The results are striking! Complex rhythms and surprising melodies that become even more dynamic when paired with the expander for voltage-controlled step selection.

Discrete Map also includes an onboard oscillator. A switch toggles between a slow and fast frequency range. When slow, it functions as a standard step sequencer. Another switch changes from Position mode (explained above) to Length mode, where the lower faders control step duration. When switched to the fast mode tho, it becomes a graphic oscillator that tracks V/Oct.

To round out the package, Discrete Map includes additional utilities for better integration with other modules. The precision adder for example allows an external voltage to transpose the entire sequence.

The A/B/C Expander further enhances functionality, adding three assignable groups for the steps. Each group gains CV-controllable threshold values and dedicated gate outputs for active steps. And because that´s not enough there's also a sequential switch. Several discrete maps and A/B/C expanders can be linked together!

Overall, an incredibly well-thought-out and entirely fresh approach to sequence generation!

Features:

8-step sequencer for a single track
Generates sequences based on any input signal
8 lower faders to position steps in time
8 upper faders to set step values
One-shot mode
Oscillator mode with V/Oct tracking
Adjustable output voltage range (-5V to 5V / 0V to 5V / 0V to 2.5V)
Precision adder for transposing sequences
Gate output
Ramp output for internal clock signal"

Bend & Twist Time with Voltage Addressed Sequencing // Discrete Map from New Systems Instruments
video upload by DivKid

"Here’s the new Discrete Map and expander from New Systems Instruments. Deeply routed in influence from the Buchla MARF & a Serge Modular style approach to sequencing, coupled with a heady mix of physics and electronics (as New Systems Instruments do so well) the Discrete Map allows you to use voltages to bend and manipulate a time map across 8 stages of voltages. From basic to more advanced sequencing, unique time and rhythm creation to some bonkers graphic VCO applications there’s a lot we get into in the video."

Follow-up to this post.

"This time, I'm not testing the DivKid patch, but my own humble idea.
It's sure, you can improve my idea. I didn't have time to do a better video, because I have to launch a new module this week...

At first, I'll using my Random*Source / SERGE modules.
And then, with my Dual Undula Oscillator. Because the VCO can work like a VCF, and th frequency can go very low.

Hope you will enjoy it :)"

Testing patch, from DivKid, from Rob Hordijks FAKE Reverb with Ring Modulation.

video upload by LARIX ELEKTRO

"‪@DivKid‬ 's releasing a very interesting video (as usual).
from an idea of Rob Hordijks.
I let you seeing all the explanations here:[below]

So, why not testing it by myself ?
At first, I'll using my Random*Source / SERGE modules.
And stupidly, I was forgetting that my DUAL UNDULA OSCILLATOR has all functions to test the idea ! So I'm testing the idea with it.
And after that, I'm digressing around the stereo possibilities of my module and the MS (mid/side) option.

Ok, I didn't have a lot of time (busy after SuperBooth...) so it's a bit "from scratch"... Hope you will enjoy it :)"

How to FAKE Reverb with Ring Modulation // Rob Hordijks ‘Poor Mans Delays’ [BETTER BLEEPS]

video upload by DivKid

"So here's a bit of story and the first BETTER BLEEPS video in a long time!

With Chris from Moog sharing Rob Hordijk's trick to emulate reverb wth Ring Modulation in the recent Superbooth video, that of course sparked questions. So strap in with a brew for a time travel trip back to 2017 where Rob Hordijk gave a tutorial with his "poor mans delay" technique and stay tuned for going through the technique and method with us in the video. Grab the free PDF and VCV Rack patch for further material on the technique. Links below.

This is applicable to many modules and bits of gear, to that point after the main demo with Manic (DivKid & Apollo View) I go through it with 4 more modules (Instruo VinCA, cLFO from AtoV, Ouija from Nekyia and A*B+C by Befaco)."
