TipTop Polyphonic Modular + ASM Hydrasynth : "Entangled State" by gattobus

video upload by gattobus

"This track came out of the blue while I was playing and experimenting with TipTop Audio Poly Modular System and my ASM Hydrasynth.

This patch sounds organic and deep, a perfect blend between analog and digital!

I loaded a custom wavetable on TTA Vortex 6 then I set up a classic signal path going through the poly filter (TTA Octopass) and the poly vca (TTA Octogain). Then I added some external modulations coming from Hydrasynth CV outs, which turned out to be the best keyboard controller for this incredible system!

Star of the show is TTA Resonator that adds a very organic and ethereal texture to the entire patch!

These are the modules in my system:

Vortex 6 Oscillator
ATX-1 VCO
Octopass Poly Filter
Octostages Poly Envelope x2
Octogain VCA
Octopus USB/MIDI interface
Octo I/O
Octovert
Resonator
Z-DSP 'ZVRB 80' Card.
Mantis Case (black)"

New OCTOLFO, Multipass, & Resonator Eurorack Modules From Tiptop Audio

Also see Buchla & Tiptop Audio 248t and 230t Incoming for new details. As always, check with dealers on the right for availability.

Details on the OCTOLFO, Multipass, & Resonator follow.

OCTOLFO – Eight-Voice Voltage-Controlled LFOs

For all Eurorack users, here comes your mega LFO. And for those of you who have already joined us on our journey into polyphonic patching heaven, this is the one you've been waiting for. The Octolfo consists of eight fully independent LFOs with plenty of controls, lots of waveforms, and the ability to load your own waveshapes. Clock-sync it or let it free-run. Use one-shot cycles of waveforms to create unique envelopes, and reset LFO cycles from your notes. All eight LFOs are available simultaneously on regular jacks and Polytip jacks—both outputs and CV control inputs. CV is mappable to parameters, and the entire setup can be saved as a “preset.” This module brings polyphonic modulation into our new world of polyphonic patching.

Multipass – Eight-Voice Multimode Filter

Please welcome the second filter in our polyphonic series: the Multipass. This one carefully recreates the rare OB-X filter design (not the later CEM-based OB-Xa), delivering the sound of the ’80s and early techno.

It features extended signal levels on inputs and outputs for an even broader tone range. LP, BP, and HP modes are poly-voltage controlled and simultaneously available per voice through Polytip, and via a mixed output jack. Each filter mode has manual gain control via dedicated faders. Frequency control is polyphonic and can be over-modulated by a mono signal with adjustable scaling. With all its poly mod inputs, this filter goes far beyond its classic roots.

Where and how much?

The first batch is ready, and we expect to begin shipping to shops soon. Price will be in the $500–$600 range.

Resonator

An extended design based on the analog resonator from the 1975 Polymoog synthesizer. This classic beauty works with everything from drums to polyphonic audio, adding lush resonating swirls.

There are three resonators, each with a selectable band. Each has voltage control for every parameter, nine CV inputs in total. Multiple gain stages (master input, resonator gain, and mix output) allow fine control and help manage clipping. Emphasis CV range boundaries prevent runaway self-oscillation. A true-bypass switch makes it easy to compare processed and dry signals—perfect for leaving it patched in and engaging only when needed.

Where and how much?

The first batch is ready, and we expect to start shipping soon. Price will be about $245.

Multiple Arbitrary Function Generator Model 248t

Status: TBA
Price: TBA

Update:

248 Boommm!

Yes yes, the MARF is here and alive! At Superbooth, we’re showing the first prototype, and it’s already 80% functional. What a monster. The range of possibilities here is truly outstanding. This thing can literally mutate based on how it’s programmed. It’s wild and often unpredictable. Is it a sequencer? A curve generator? For notes or modulation?

Well, it’s a function generator, an arbitrary one at that, and in practice, it’s more complex than we could’ve imagined.

We were unsure about this module. There’s no fully functional original unit we could test, and all the data comes from Don’s 22-page user manual from 1977, along with insights from Kyle Swisher and Todd Barton, who’ve been investigating this for years. Exciting times!

Where and how much?

Wish us luck—we hope to release it this winter. Pricing is expected to be in the $650–$950 range. As always, we’ll do our best to keep it affordable and give you plenty of time to save up.

Triple Envelope Follower Model 230t

Status: TBA
Price: TBA

Update:

Triple Envelope Follower Model 230t

Here’s another wonderful vintage design: three AC amplitude followers with excellent sensitivity and highly accurate CV reproduction of the incoming signal. Both sensitivity and decay time are adjustable across a wide range. The circuit is so sensitive, it can even produce output from the noise generated by rotating the sensitivity knob—pretty cool.

The pulse output can generate either a transient (trigger) or a sustained gate signal, depending on the switch setting. We’ve been using it extensively in our systems and discovering tons of creative patch ideas. Where and how much?

It’s heading into production, with the first batch expected in July 2025. Pricing will be in the $200+ range.

Polyphony Without Spaghetti: TipTop Audio ART Modular

video upload by HAINBACH

"I love new music technology. When I heard about TipTop Audio's new ART system that allows for polyphonic pitch, gate and velocity information to be transferred via regular patch cables and their own multi-tip USB style cables, I was intrigued. I never thought of Eurorack as being a fun tool for polyphony, as it requires a lot of modules and a spaghetti mess of connections. Can this tech change that?"

Buchla/Tiptop 292T RoHS | Buchla 200 series | Episode 13

video upload by Cinematic Laboratory

"This week, the 292t quad lo-pass gate finally arrived at the EU and the UK, but without the toxic vactrol components. As you may know, vactrols require the use of cadmium, which is mildly radio active and it should not end up in the environment. The 292t RoHS can safely be disposed when it turns out it ain't no Buchla anymore.

In this video I'll do a quick test using both versions but as always, TipTop Audio did a truly amazing job. It still has the magic of the original 292c, but it's a bit quicker because there's no vactrol memory effect. The bad news is that you can't strike it with a short blip, ping or trigger. The good news is that it sounds as tight as a doornail and when you use envelopes, you will not get the feeling it's not a 292.

Still, it's impossble they will respond in the exact same way. Even the original vactrol 292 would expose tiny differences from unit to unit, where the RoHS version will be consistent. I am a huge fan of LPG's and I always assumed you can't have a decent LPG without vactrols. The excellent Natural Gate from Rabid Elephant already proved me wrong a long time ago, and the 292t RoHS confirms it. There's no need to get yourself an 'original' 292t with an illegal import. The EU/UK version is fine!"

Message from the Mothership to all 200t users on Planet Earth!

We are thrilled to bring you the Quad Sample & Hold and Polyphonic Adapter Model 264t. The module is now shipping, and pre-orders are open at our dealers. Price: $265. [check with dealers on the right for availability]

Don Buchla designed the original 264 in 1970, but only a few were ever mad,e. This module features high-speed sample & hold circuits that can also switch to track & hold, delivering the exceptional performance you’d expect from a Don Buchla design. To push the boundaries further, Don added a groundbreaking feature: the Polyphonic Adapter. This was a bold vision at a time when polyphony was virtually unheard of, synth pioneer Tom Oberheim wouldn’t introduce the world’s first polyphonic synthesizer, the SEM, until 1975. With the 264t, we’ve taken Don’s polyphonic concept one step closer to full realization. We’ve added ART outputs that can drive multiple oscillators equipped with ART, such as the 259t Complex waveform generator. Plus, we’ve incorporated built-in scales, adding a complete ART quantizer working seamlessly alongside Don’s original analog circuits.

"For better or worse, we got into 4U Buchla format when we purchased the ZIMM system from Zerosum Inertia last year. And that purchase perfectly coincided with us liquidating the massive Tokyo Tape Music Center Buchla TTMC 100 eurorack system and TipTop Audio & Buchla 200 Eurorack system we had amassed over the years. One of the modules I missed was the handy 106 mixer. We had one by TTMC and one by Catalyst Audio. So we just got this Ebolatone CP-3 Moog mixer in Buchla format. This video was supposed to be a test of that mixer, but I got sidetracked."

Two New Synthesizer Evolution Books by Oli Freke

Details follow via the author, Oli Freke:

These two new volumes in my Synth Evolution ‘zine series were launched at last weekend’s SynthEast event in Norwich, UK. They are Volume 3: Modern Classics, and Volume 4: Modular Greats. I’ve moved into the 21st Century with these two! As ever, they feature my signature hand-drawn illustrations and are full of facts, figures and tech-specs:

Volume 3: Modern Classics

Synthesizer Evolution: From Analogue to Digital (and Back) author Oli Freke returns with a new volume in his Synthesizer Evolution A6 zine series. The first two volumes (Vintage Synths and Drum Machines & Samplers) focused on vintage electronic instruments from the 1970s and 1980s. Volume three moves into the 21st century, showcasing a selection of the most interesting, impactful, and—arguably—best synthesizers of the past two decades.

The synths in this book celebrate the vast range of sonic possibilities now available to musicians and producers. From analogue wonders to extraordinary digital creations, from tightly designed monosynths to open-ended polyphonic beasts, each one is more marvellous than the last! Also featuring ‘Desert Island Modular’ choices from Robin Vincent, Steve Davis, Panic Girl and more.

Tiptop Audio Polyphonic Modular System - In The Studio

video upload by Tiptop Audio

"To celebrate the release of the first set of Polyphonic modules, the Vortex6, Octogain, Octostages, Octopus, Octovert, and the Polytip Patch Cables—we invited Simone Miceli to join Piero Fragola in his home studio in Florence, Italy, to compose a song. This piece demonstrates how a violin, vocals, and these new Eurorack modules work together to create music.

Except for the vocals and violin, which were recorded separately, all synth voices were captured in a single take from the system in the video. The leading sound in the track is the Vortex6, with all six voices gliding seamlessly between notes.

In a polyphonic synthesizer, we know that the key building blocks like oscillators, filters, and LFOs are hard-wired under the hood of the synth. In modular poly, we open up all the possibilities that modular synthesis provides--IN POLY!
Welcome to the future."

242T Programmable Pulser | Buchla 200 Series EP.12 | By Tiptop Audio

video upload by Cinematic Laboratory

"I've been wondering how to approach this episode. If this were a module review, the 242 would not be able to stand up against modern 21st century sequencers. It's basically a 12 step sequencer with three rows of pulses so you can't even do a four on the floor. We need to remember we didn't have those in the late 60's, so let's not worry about that too much.

The classic pin-controlled 242 was custom made for CBS and it didn't carry the Buchla name. CBS (California Broadcast Systems) was licensed to build and distribute the 100 series and it eventually stopped because CBS didn't see a future for electronic instruments. I guess you need to have a long term vision, and CBS clearly had a different one. Regardless, the 242 is extremely rare. Fortunately, the 242T is not. Tiptop abandoned the pins and fancy illuminated buttons in favour of small buttons and a LED matrix. The 242t is a Tiptop first, and a CBS/Buchla later.

The 242 is a retro-futuristic trigger sequencer with some weird outputs. The ABC pulses are extremely short, but the alternating outputs are longer. Then, there's this SAW CV output which is tied to the master clock. There are start/stop and reset inputs and a CV controlled Period which is not unlike a frequency when pushed to audio rate. I tried to ping the 296 Spectral Processor with the ABC outputs, but these are barely audible. If you want to ping a rhythm on the 296, you'll need to use 281 envelopes and patch from there. Using them to ping a 292 vactrol is just wonderful.

Stazma and Todd Barton made excellent video manuals, so I am not going to explain the module in this video. Since nearly every Buchla module is either quad or dual, I used two 242 modules. I had to. Imagine it's the early 70's and it's the Dawn of Synthesis. We have no idea what the future will bring."
