Sorry if I wasn’t clear. The green line is what you get if you run the red line through an attenuverter set at CCW - including those on the Voltage Processor/Dual Processor and the bottom of the Active Processor, and probably on the Scaling Processor as well - it basically multiplies the voltage by -1, so it is a mirror image below zero volts like a reflection of pines on a lake.

The blue line is what you get if you then also add positive offset to the green line, bringing it into a useful range for a Serge VCA.

If you were to turn the attenuverter only half-way CCW, you would change the shape of the green some but only in a squashed or reduced-range way - there would still be peaks where the red had valleys and vice-versa.

If by any chance you don’t mean rms limiting and just peak limiting…

It is my understanding that any opamp is already a limiter that is limited by the power rails. You could find something to increase the gain by more than 1.0, pushing it past the rails and then attenuate the output of that signal.

Or… maybe just use a peak & trough or analog logic (cgs) to set a narrower threshold, clipping high and low values.

ok thanks, all clear now – i really appreciate the explanation!!

Thanks, yes, that’s what I’m pricing up now. Waiting on @loudestwarning :wink:

Thomas Ankersmit, tonight at a Muse en Circuit for SERGE MODULAR #3

so inspiring! some of the most melodic sounds i’ve heard from thomas at the beginning and end. that intense crackling sound was so captivating too. around halfway through. any idea how that was made? maybe the variable bandwidth filter. i’ll get a better timestamp in the morning…

wow, those are some pro twiddles. Also I know there are a lot of panels but I’m floored that he can get 40 minutes of diverse and interesting music out of that system without repatching. Inspiring indeed.

I did a workshop with Thomas Ankersmit recently at Rewire Festival in The Hague, where he talked quite a bit about his work process, both in the studio and live.
Very interesting and inspiring, even if I don’t have a Serge (or even another modular system).

Some of my main takeaways:

He uses only Serge (apart from a matrix mixer that I didn’t see in this video; maybe that is used only when he performs with a more compact setup), but some of the things you hear live are samples of Serge generated sounds that come from experimenting in the studio. The samples are triggered using a very basic sampler-type patch in Max/MSP; the triggered samples from the laptop are sent into the Serge, and are often processed live.

He chooses not to use sequencing or looping, wanting the performance to be as hands on as possible. Everything that happens, sound wise, happens because a knob was turned, a gate triggered, sometimes a cable plugged, or unplugged.

He uses relatively simple patches on the Serge, at least in the live setup. No intricately interlinked, or quasi generative patches. This, again, is in line with the idea of playing the synth in the moment. Also, intricate patches often have very specific sweet spots, which make them hard to ‘perform’ live.

As a result, the entire system is basically a collection of 5-10 (mostly) independent, small, patches that are then played at different moments in the piece.

No processing or effects on the final output. So, no reverb (given that there is no Serge reverb). A sense of space is created by different means (some of his sounds really sound huge).

Beginning and end of a long piece are often fixed/composed. In between it is more improvised, but with some predetermined ideas about sections and pacing.

@AlvaroDeCampos Then I specify that La Muse En Cercuit the place which organized the three evenings of concerts has a historical Serge system manufactured at the base for Jean-Claude Éloy. It is on this system that Thomas did a residency and that he used for the concert. So it’s not his usual configuration. He had some Max/Msp patches including samples from the same system but not his matrix mixer.

Sublime indeed - probably my favourite recording of hers. Interesting to learn that a Serge system played a part in its composition, I’d previously assumed it was purely 2600 and tape loops.

It was a nice workshop. Also interesting how he described tuning his oscillators to resonant frequencies in the spaces he performs in. Parts of spaces would start vibrating, making sound emanate from other things than speakers.

thanks for sharing about the workshop! there’s a great interview where he talks about sound checking at berghain and using the resonance of the space -

What has been your most challenging composition or project and why?

I’m rarely happy with the music I do so to me it all seems challenging, even when it probably shouldn’t. Maybe a commissioned project I did for CTM and Berghain in Berlin, in early 2017, based on the architectural resonance of the building.

The soundchecks were fantastic; the sound engineer and I did them in the middle of the night after the Berghain employees had all left because everyone in the building had complained after the first try. Berghain has this incredibly powerful 6.1 PA system and we turned it up 100%, which they normally never run it at. The engineer was like “You mean all the way up? Like actual full capacity?

We’ve never really done that before, but sure!”. The vibration was so intense that we were holding on to tables and railings to not lose our balance. Berghain is a big, complex space made out of concrete, metal, and glass. The vividness of the building’s response was very beautiful. Just by varying frequencies and intensities slightly, all these creaking/moaning/breathing sounds would emerge from one of their metal staircases, for example.

also this book he recommends in the interview looks amazing for serge haha

I listened to this performance twice today… it was so good!

found this picture on flickr earlier of a 3 panel setup of his + the switchmix. gives a pretty clear idea of how he used the matrix as a master controller, via tracing the various connections from the audio mixers to the filters, multipliers, etc. to the ins and outs. god this would be so fun to mess around with!

Thank you for these details. I like the idea of focusing on Serge to prepare the material for a live performance and process them in a much more basic patch. It seems a smart way to use the Serge system. Very inspiring. The other thing is that he doesn’t loop the samples but triggers them. So it becomes more hands on, as you say.

Btw, I still can’t figure out how Marion performed so well after only one year practice. And that patch seemed quite complex.

I was in a workshop he gave in Cologne… One of the tricks he showed to get a a very crispy and pointy sound was sending white noise signal into the NCOM. by moving the comparator knob and the divider you can get a lot of variations, specially by moving the comparator knob and crossing certain threshold, he would get a “squishy” sound… Something between supercollider’s Dust.ar() and the sound of separating velcro tape…
Another one that surprised me a lot, sound and conceptual-wise, was how he achieved some sort of ‘fake reverb’ by sending white noise to the ResEQ, and then moving gesturally by hand different bands, one after the other at slightly different speed… that way it gave the impression of the sound diffusing in space.

Not only his patching chops are great but he’s really skilled with the hand gestures and really performing the synth.

Really love those melodic sounds. It was a great surprise.

@amgnowhere, it seems he uses NCOM quite often to create sounds. After a concert I asked him about a specific sound and he said it was essentially NCOM feedback with random modulation. I guess he usually records these kinds of some very simple but interesting, unconventional patches and processes them live.

very cool. the sound i was thinking of starts at 16:32 from the performance yesterday. sounds very much like what is being described for the ncom
