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

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?"

The Seventh of Four

video upload by davidryle

"A new project idea to use the synthesizers.com Q170 MIDI GATES module to affect broad changes to the composition within the modular system.

The Q170 has eight output jacks for sending 5V gate or trigger voltages to the modular system. I used my DAW (Cubase) to construct timings for various parts of the modular.

The first four outs were used as pulse gates for the Delptronics and TipTop drum modules. The Kick, Snare and Open and Closed HiHats.
The fifth out is to the Q169 vco's AMP input. That vco is used for the bass line so controlling the on-board vca will mute or enable the voice.
The sixth out was to enable the Dove D900 sequencer to run/stop. The sequencer is feeding pitch voltage to the Synthetic Sound Labs Woven Spirits (MI Plaits). This is the chord pad sound. I used the DAW to pulse the gate info when I wanted the sequencer to reset at certain parts.
The seventh out was to send a continuous gate to the STG Soundlabs Time Buffer. The Time Buffer is receiving a sync-bus 24 ppq clock and run signal. I have a panel access to these with jack inputs so I sent the 5V gate to the RUN input. This allowed me to use this to start and stop all sequencer motion from the DAW.
The eighth out is to a Lower West Side Studios triple switch. This switch is used to add an offset voltage to the Woven Spirits Harmonic control.
The other fun part was playing the LWSS triple attenuator. I had three parts run through the module. The pair of STG VMS sequences were percussive background parts switched in and out as needed. The third part was a pulse version of the pad sound.

The Matrix duet in the mid section was clocked from the STG Time Divider module. Both Matrix were set with very closely aligned slider settings but the "Z" sliders were offset for variety. They sent pitch voltage to the TZ-VCO's from SSL. The duet were sent through the STG Post Lawsuit Filter and an Empress reverb/delay pedal.

Other outboard effects were the Meris Hedra for the bass line and the EMX Grand Canyon for the steady pad sound."

Velocité - full album (Mike Oldfield meets Air & Tame Impala)

video upload by Caught In Joy

"Inspired by the fluid energy of Tangerine Dream, the layered elegance of Mike Oldfield, and the dreamlike pulse of Air and Tame Impala, this album explores the strange intersections of speed and stillness.

Velocité is a deep, cinematic dive into motion, memory, and momentum—an hour-long journey shaped by analog synths, ambient textures, and hypnotic rhythms.

Created live and mixed with obsessive attention to detail, Velocité captures that fleeting feeling of being in transit—somewhere between the past and the future. Best experienced in one uninterrupted listen.

Composed, mixed and mastered by Caught In Joy. Karol Pokojowczyk uses Bitwig, Moog One, Moog Matriarch, Prophet-10, 3x Moog Mavis, TipTop Buchla modules, Make Noise Strega, Strymon Magneto, Arturia V-Collection and an army of guitar pedals. Performed and recorded live on tape with TEAC 80-8.

Buchla Tiptop 264T | ART protocol hacking with XAOC Drezno

video upload by Cinematic Laboratory

"According to Gur from TTA this was unlikely to work, but 'unlikely' is not impossible. The ART protocol is something like analog encoded digital data used to be transferred over regular patch cables. It carries information that can be used to play quantized notes on an ART capable VCO like the 259t (and obviously the ART series from TTA). I tried using XAOC Drezno to convert the ART signal to bits, and then scramble a few before recoding it back to analog. This is just an experiment and it was a bit too much off-topic for episode 14. It would also make the video too long and nobody's watching the end of long videos anymore. It makes me wonder if this could also work on MIDI data, but that's for another day."

Buchla Tiptop 264t | Buchla 200 Series | Episode 14 | Quad Sample and Hold / Polyphonic Adaptor

video upload by Cinematic Laboratory

"The original Buchla 264 is a very rare module, released in the 1970's. So it's important to realize it's a very primitive way of adding polyphony to a modular system. It's not that different from an early analog polysynth, where voice cards were used to activate two or more voices from a keyboard 'switch'. This is another fine example of doing easy things the hardest way possible, so there should be some reward in it. Apart from the polyphonic switching mechanism - you'd need four VCO's, four envelopes and four VCA's to switch between. I'll start with four Plaits, which can trigger their own internal LPG while distributing Marbles CV/GATE between them.

Then I used the Buchla LEM 218 keyboard to try and make chords. It didn't work so well, because the 264T is too slow picking the right voltage for the right key-down event. The 218 already outputs quantized notes in the 12-TET scale, so how hard could it possibly be to 'sample' the voltage from the played key and hold it? On the original Buchla 264, people used a gate lag (with the 281 envelope generator), to sample the voltage first, and trigger the hold with an end of cycle, just a few milliseconds later. Fortutnately, the 264 also has track and hold. In this mode, it can simply track the keys from the 218 keyboard, and hold it on key down. Works like a charm!

Regardless, this old-school analog polyphony is a lot of work and requires either a lot of modules, or specialized quad versions of your basic VCO, VCA and Envelope Generator. However, the module provides lots of cool resources you can use on a simpler setup, and results may be even cooler than trying to create polyphony. For instance, the polyphonic adaptor can double as a clock divider, which is missing from the current Buchla/TTA 200 series. It's super useful to clock a delay or sparse event. When combined with the 242 pulser, you could use a 11-step sequence, and pick every 2nd, 3rd or 4th event, creating all kinds of odd variations without changing the 'pins'.

Then there's ART, which is a new digital protocol for tuning a VCO, and sending quantized note and gate information. This requires an ART capable VCO like the 259T. While it's tempting to use two of those, it's much more fun to just use the principal VCO in ART mode, and use the modulation VCO in standard mode. Your voice will be in tune with other sources, but you'd still be able to create some new textures and leads. Quantized notes will steal some of the Buchla magic, so this is a best of both worlds. So if you're not pursuing polyphony (which isn't unwise), the 264 is a great source for stepped random voltages, divisions and quantized notes. Highly recommended for all you generative music lovers."

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.
