7555VCO 1

"Wide ranging sawtooth VCO with the hardest hard sync around."



via nonlinearcircuits

"Not the most exciting name, I simply wanted a 4HP sawtooth VCO to sit next to the Spectrum Shaper.

It is based on the Utility VCO in Electronotes EN67, which was based on designs by R. Tenny (Electronic Design 11/10/75), J.L. Brice (Wireless World (6/76) and others.

It tracks very nicely, turn the CV pot to max for 1V/oct, ranges from approx 10Hz to over 100kHz and supplies 10Vp-p sawtooth and square waves.

The Sync is the hardest of hard syncs around. I left out the capacitor usually used to turn sync signals into a pulse, so if you feed a gate or slow CV signal into Sync the VCO simply stops, think of it is a bonus VCA. Of course, if you use an audio rate sync signal, it works as normal.

It is a pretty easy build. not many parts. Do not mix up the BCM847 and BCM857 dual transistors, see the build notes for where to install a 1k tempco."

"Yesterday I took a day off and went to the beach.
As I often do, I brought some of my equipment with me and this song came out.
Everything was composed, recorded, and filmed there.
When I feel lost, sometimes it happens that music finds its way through me and comes out by itself. When it happens, I feel alive, and that gives me hope in the future.

Intruments used: Teenage Engineering OP-1 feld, Roland R-05 Wave recorder.

RESONATORS | Rings | PolyMoog | Tiptop Audio | Haible by R*S

video upload by Cinematic Laboratory

"In this video, I'll try to explore the concept of resonators in electronic music. I am not sure I am correct here, but I guess the first official Resonator was from Serge, followed by the Resonators in the fist PolyMoog. Buchla may have closed the line with the 292 Spectral Processor, which is also a resonant array of filters. Resonant filters is what all these modules have in common. Jurgen Haible revisited the Moog resonator in the 21st century, and Emilie Gillet perfected it with the Rings module. TipTop Audio also made a faithful recreation of the Polymoog resonator quite recently.

My interest in resonators was ignited when I saw a 17 year old low-res video from Kenneth Elhardt running a Jupiter-8 through an isolated Moog resonator unit, turning clearly synthethic sounds in to very convincing voices, brass and woodwinds. I've used a few snippets (transformative / educational) and added a link to the original. Mr. Elhardt also has a few videos on his channel where he recreated 'medieval' music on a Synthesizer.com Moog clone which is an amazing listen and a hidden gem on the tube.

What I did not know, is that this video may have also inspired Haible and Tiptop Audio to recreate the resonator.

But wait. Rings? Yep. When not plucked and using the IN, you'll pass a sound through 48 digitally controlled 'virtual' filters. So don't pluck it. Resonate it."

8/5/26 Metasonix D-2000 & R-57 + Zerosum Inertia Horripilation & TVM23 + MFB SEQ-1 & LFO & ADSR (…)

video upload by Cfpp0

"This rancid beat is starring Zerosum Inertia’s Horripilation module and the S&H from the MFB dual LFO module. The Metasonix D-2000 is being triggered by the MFB SEQ-1, clocked by ALM Pamela’s New Workout. The D-2000 1/4” output is converted to 3.5mm and multiplied by the Doepfer A181 with one copy going to the Metasonix R-57 and the other copy going to the Zerosum Inertia Horripilation into the TVM23 VCA. Both the TVM23 and the R-57 are being modulated by the MFB dual ADSR. The Horripilation filter CV is modulated by the MFB dual LFO triangle output, while the S&H output is modulating the CV on the D-2000 Drum 2, and the left CV input on Horripilation. There are two Alesis MIDIVERB II units. One is set to preset 05 and the other is set to preset 40."

JHaible TAU Phaser 'The Pipe' 2026 by Random*Source

video upload by Cinematic Laboratory

"Today I am proud to show off the new TAU 2026 phaser edition from JHaible x Random*Source for Eurorack. Obviously the core 'Pipe' sound didn't change because it needs to remain faithful to its history and heritage. It's not supposed to sound different from the previous R*S version. But it does. This is because the TAU '26 features two inputs and two CV inputs instead of one. Also the inverted (-) V/OCT is dropped. Visually, the panel now matches the Serge Modular line so it neatly blends in with your Serge 3U gear.

So is it a 20 pole- or an 18 pole phaser? Is it even important? No. What's truly important is the PIPE configuration of 20 transistors in a classic ladder topology. Your input will actually flow through the circuitry like air in a tube and I think it's absolutely stunning when you run noise through it. However, when you bring a lush pad, the TAU will redefine 'lush' into a pseudo stereo swirl that doesn't make you seasick.

When you crank up the feedback and hit it with some trigger 'stick' or chain, the TAU will make remarkable percussion. The Tau is also available in 4U. It's still a Haible, but it carries the 'Serge Modular' branding and comes with an extra mixing panel.

Synthesizer Pioneer Patrick Gleeson Has Passed Away

Some sad news in via The Alan R Pearlman Foundation and The Bob Moog Foundation

Celebrating the Life of Composer and Synthesizer Pioneer Patrick Gleeson

We received the sad news about about the passing of Patrick Gleeson. With respect to Pat's widow, and in conjunction with the Bob Moog Foundation, we are sharing their Press Release:

Legendary Master Synthesist Patrick Gleeson Dies at 91

On behalf of the estate of Patrick Gleeson, the Bob Moog Foundation shares the passing of the legendary electronic music pioneer. Patrick Gleeson passed away on July 19, 2026; he was 91 years old. Gleeson may be best remembered as the owner of Different Fur Studios, and for his subsequent work with Herbie Hancock. However, his career stretched well beyond those accomplishments, including producing and engineering for a multitude of musicians, recording solo albums, scoring soundtracks, and performing live.

Wendy Carlos once wrote of Patrick, "Our eight-year wait for someone else to explore electroinc music realisation with what we judge to be appropriate technical standards and musical taste has ended. In short, one hears the ears of a gifted musician at work, in a field where one must exercise unprecedented discipline and self-control."

You can read much more about Patrick's significant contributions to the world of synthesis and music HERE."

nonlinear circuits spectrum shaper

"I'm still learning how to use this thing but here are some excerpts from a patch with Tinkle and FM OP via Product wavefolder both fed into the Spectrum Shaper."

via nonlinear circuits

"36 channel voltage controlled comb filter aka string filter.

This module has some history. In 2018, I was part of a team putting on a show with CellF at the Todays Art festival in Den Haag. I popped down to Rotterdam to visit Dennis (aka Mono-Poly) and his studio of vintage lab gear. Dennis had an incredible patch going centred around a Bruel & Kjaer 36 channel Spectrum Shaper. Listen to his album Testlab to hear how it sounds. I just knew I had to make something like it one day. This type of filter is often called a ‘String filter’, used to emulate stringed instruments tho don’t feel limited by that.

Fast forward to 2026, I read an AES paper by R. Burhans describing his 36 channel comb filter. It reminded me there were some designs in Electronotes, so I looked them up and discovered they were both inspired by and heavily influenced by Burhans, particularly in terms of the comb filter frequencies and spacing. One was a 40 channel version by Ian Fritz using transistor based filters. He had an interesting mod, originally suggested by Lester Ludwig, where each set of 6 filters had a feedback pot. Some screenshots from these articles are at the end of this build guide. The relevant Electronotes issues 107, 115 and 116 can be found online.

The Bernie Hutchins design used 39 regular op amp based filters, along with Ian’s feedback per 6 filters mod and added an inverter so the feedback could be positive or negative (so, centre off). Negative feedback ‘flattens’ the peaks somewhat and smears the sound, positive feedback makes the peaks narrower and higher (if tuned for it, you can make them self-oscillate, see notes). Bernie also added a noise gate on the output, summing 39 channels is always going to be noisy.

The audio is split three ways:
—running through the left side of the Zerosum Inertia 5654 into the TVM23 VCA into the Metasonix R-54 MKII into the TVM23 feedback section into the Zerosum Inertia Horripilation.
—running through the Metasonix R-53 into the Zerosum Inertia ZI61, with another copy of the original audio, amplified by the right side of the 5654.
—running through the right side of the 5654 into another R-54 MKII into the Zerosum Inertia Voltage Controlled Annihilation into the Metasonix R-51.

Some reverb was blended on the CXM 1978."
