Here comes the MARF - Tiptop Audio 248t Demo Video

video upload by Stazma and Tiptop Audio

"Here we are, the "MARF" aka Multiple Arbitrary Function Generator Model 248 in now in a reality in eurorack: all hail the 248t!

In this video I'm going to show you a bit of everything it can do (it can do a lot) but believe it or not I'm not going to go too deep. I'll try to go a bit deeper in some of the many rabbit hole of this things in future videos."

Introducing Luna: A Lunetta style groovebox & eurorack synth module

video upload by mylarmelodies

Check with dealers on the right on pricing and availability.

"This is your official introduction to the Neutral Labs Luna - a new lunetta-style “groovebox” desktop & eurorack compatible synth. It’s patch programmable, letting you both create tones and rhythms from 5 oscillators (2 with step sequencers inside), logic and pattern generators, all at the same time. Three 'LPG's take the raw tones and let you gate and filter them. 13 effects in 2 blocks effect and shape sounds further.

Enormous thanks to Martin at Neutral Labs for commissioning me to make a vid of this. The world needs more shift registers. Note: I used my own red Tiptop Audio Stackcables in the video, but the desktop module comes with 12 braided patch cables."

Update:

What's a Lunetta synthesizer and why should you care? // LUNA from Neutral Labs

video upload by DivKid

"Join us for an exploration of what Lunetta Synthesizers are, what the new Luna from Neutral Labs is and why you should care.

The short answer is that it’s an interesting series of raw digital building blocks from a sonic sculptor (Stanley Lunetta) with lots of modern quality of life features that allow you to approach timbre as rhythm, rhythm as timbre then round that out with low pass gates and FX.

"Logic, Unbound. Meet Luna. The first serious Lunetta synthesizer.

Look beyond clean waveforms and predictable polyphony. Luna will take you back to a time when digital didn’t mean perfect. It meant raw. Inspired by the subterranean DIY culture of the 70s and 80s, Luna is a love letter to the Lunetta machines of old: Living, breathing organisms built from CMOS logic chips. But where those machines were fragile experiments, Luna is a weaponized instrument of sonic confusion.

The Nervous System Exposed. True to the Neutral Labs philosophy, we don’t believe in hiding the magic behind an opaque face plate. Luna features exposed CMOS inputs and outputs right on the front panel. You're not just patching cables, you are rewiring the brain of the synthesizer itself. Combine signals, bend logic, and physically intervene in the computation to create sounds that shouldn't exist.

Rhythm is Timbre. Timbre is Rhythm. In the world of Luna, there is no difference between a sequencer and an oscillator. The same digital pulse that drives a bass line can be accelerated into a screeching lead or folded into a metallic drone.

5 oscillators provide the raw material. A chaotic array of logic blocks (XOR, NOT, AND, shift registers, counters, multiplexer) will chew up those signals and spit out complex, evolving mathematical noise.

Taming the Digital Mess. Raw logic can be harsh. To turn this binary chaos into music, Luna feeds its digital soul through 3 organic low-pass gates. These analog circuits impart a natural decay and percussive punch to the madness, transforming mathematical errors into bongos, plucks, and thumping basslines.

Drench it in Atmosphere. Once you’ve constructed your signal, destroy it again. Luna comes equipped with a suite of effects — distortion, delay, reverb, chorus, bitcrusher, phaser and more — to smear your logic into a wash of ambient bliss or gritty industrial texture.

5 oscillators
logic gates (2 XOR, 2 NOT, 2 AND)
5 logic blocks (5-step ring counter,4-bit binary counter, 2 shift registers, 4-channel multiplexer)
3 touchpads that generate logic signals
3 channels for audio manipulation (low-pass gates with adjustable decay and switchable trigger mode, gain, tilt EQ)
13 audio effects that can be freely assigned to 2 effect slots running in series (drive, delay, reverb, 6 filter types, bitcrusher, phaser, chorus, comb filter)
CV control for effects and 2 oscillators
MIDI control over 2 oscillators, all 3 low-pass gates, and 3 logic outputs (MIDI TRS A socket)
2 sequencers with up to 64 steps, syncable to clock or MIDI
audio output is headphone compatible
available as a desktop synth or 42 HP Eurorack module (desktop version comes with a 12-pack of black/gold braided patch cables)
See more videos and photos on Instagram.

Note: For sustainability reasons, the desktop version does not come with a USB power supply, just a USB-A to USB-C cable. You will need a 5V supply, such as a phone charger, power bank or laptop.

Note: The desktop version has a Eurorack power header and can be placed into a Eurorack. The desktop case however has 5V USB power and no Eurorack rails, you cannot use it as a 42 HP rack without modifications."

The "Easel" Spirit in 3U - A West Coast Eurorack Deep Dive

video upload by Sean Graves

The following is in via Sean Graves, who had the following to say:

"The piece, 'The 'Easel' Spirit in 3U: Rebuilding a Buchla Soul in Eurorack,' documents my five-year journey to replicate the specific workflow and 'soul' of the Buchla Music Easel using a curated Eurorack system."

"This post explores the creative power of 5-step sequencing (the 'migrating downbeat'), the 'origami' of wavefolding via the Verbos Complex Oscillator, and the organic harmonic dampening of vactrol-based Low Pass Gates. It’s a technical yet accessible look at why the West Coast workflow remains the 'holy grail' for performance - based synthesis."

The full write-up follows, with a demonstration of the system in the video above.

The “Easel” Spirit in 3U: Rebuilding a Buchla Soul in Eurorack

The Buchla Music Easel is legendary. It isn’t just a synthesizer. It’s a self-contained performance ecosystem. For many of us, the “Easel” workflow is the holy grail of synthesis. However, instead of chasing original hardware, I’ve spent the past five years rebuilding its specific soul within the Eurorack format. Because everyone deserves a hobby, right?

The Chef vs. The Sculptor
Most East Coast synthesizers work like a sculptor. You start with a massive block of harmonic noise (Sawtooth or Square waves) and carve it away with a filter. The Buchla workflow is different. It’s like being a chef in your own Hell’s Kitchen. You start with basic, “bland” ingredients (sine waves) and spice them up with Frequency Modulation (FM), Amplitude Modulation (AM), your choice, and then fold until the sound sizzles.

My current rig recreates this spirit by focusing on three pillars: Uncertainty, Complex Oscillation, and the iconic Sequential Voltage Source.

Part One: The Modulators (The Brain)
In a true Easel style setup, the Tokyo Tape Music Center 5-Step Sequencer acts as the brain. While most modern sequencers favor 4-8-16-32 steps, the 5-step limitation is actually a creative superpower.

Buchla 259t exploring sounds with explanation

video upload by VoxModula Archives

"The Buchla 259t by Tiptop Audio is my favourite complex Vco, in this video I am exploring its sounds with some explanation. The timbers and all the modulation of this modules are just incredible! Let me know what you think of it in the comments."

MATRIX VCF & Voltage Control - Creating presets with fixed voltages

video upload by AJH Synth Official

"Here I'm using Pressure Points to select different sounds/settings on the Matrix VCF - this filter has full CV control of all functions, including the selection of all 16 different filter types (Mode). Because the Matrix has such a huge range of filter sounds, it is very useful to be able to recall them instantly using a fixed-voltage controller or sequencer.
I'm also feeding it 2 VCOs and noise initially, but later replacing the raw sawtooth waves with the same saw processed by the WAVE SWARM - this is a sawtooth animator, creating 12 additional faux saws from 1 or 2 incoming oscillators to create a fat 'super saw' effect.

Video & Performance by @DreamsOfWires

The AJH SYNTH Eurorack modular range consists of high-end modules, all hand-made in the UK, most of which are based on classic, vintage designs, authentically recreating the circuitry of much sought-after analogue instruments and technologies of the past, whilst greatly expanding them, and bringing them to modern Eurorack levels of convenience, limitless flexibility, and reliability.

"Testing the TipTop Audio / Buchla 248t module. The 248t has eurorack level CV/Pulse outputs as well as the ART serial data outputs to drive modules that will receive ART note data. This configuration has a TTA 259t controlled by the ART signals and the Buchla 208c Easel Command controlled by CV/Gate (v/oct scaling).

The module is pretty massive - 72hp."

TipTop Buchla 200t

video upload by Oxix52

"I sold off my 200e system about 3 years ago. I recently put together a TipTop Audio 200t system. It's been pretty fun. This is a short play with the 259t as the only audio source. I used one non-Buchla module--the Intellijel Springy 2. It's mono output is being sent to the 296t to make it stereo."

TipTop TRIAX-8 Polyphonic Thru-Zero FM Oscillator - What is TZFM?

video upload by gattobus

"Here's a quick presentation and audio demo of the new TipTop Audio TRIAX8 Polyphonic Eurorack Oscillator.

00:52 - What is THRU-ZERO FM ?
03:45 - XOR Waveform
05:45 - Music Performance

This video is sponsored by TipTop Audio"


"Meet the TRIAX 8 , an oscillator like no other, featuring 16 analog triangle-core oscillators with full note polyphony and patching. The TRIAX8 is a landmark in synthesis technology, combining true polyphonic patching and full note polyphony with the creative and joyful hands-on workflow of a modular synthesizer. Every function has its own knob, and all modulation inputs are ready for patching with patch cables. Beneath this interface lie 16 true analog oscillators, real circuits built from semiconductors, capacitors, and resistors, each one alive, drifting naturally with temperature and with the magnetic and electric fields they generate. This is the sound of analog: full, warm, organic, and never the same twice.

In this demo, we showcase just a glimpse of what the TRIAX8 is capable of, and how easy it is to design sounds through instant patching. We focus mainly on pads and drones, with a touch of arpeggios. A note about video sound quality:
YouTube plays compressed audio, which significantly affects sound quality. Compared to the original recording, the audio will generally sound muddier and harsher in the highs. However, it still provides a good sense of the character and tone of the demoed device.

Patch Overview for this video: For modulation, we used the OCTOLFO to randomly patching LFO signals into the TRIAX 8’s CV inputs. The audio output was routed through the OCTPASS 24 dB low-pass filter and then into the OCTOGAIN. From the OCTOGAIN’s stereo outputs, the sound was sent to the Z-DSP, where some patches feature reverb or delay from the Z-DSP. For control, we played notes from Ableton through the Octopus, or used G-Mode sequencing on the Octopus and NerdSeq."

Semi-modular synths are great, and even with a sizable eurorack set-up I find myself gravitating to these complete, self-contained instruments more and more, to get the enjoyment of patching without the option paralysis that a full modular synth sometimes inspires.

Nevertheless the big benefit that a full modular set-up gives you is that expandability and flexibility to build out what your setup is capable of by adding or swapping out modules.

But semi-modular lovers need not feel left out! There are numerous bits of kit out there which can help you get more from your semi-modular synths, expanding their capabilities and sonic palettes.

264t & 242t Chord Machine - Tiptop Audio & Buchla

video upload by Stazma

"From plucky polyphonic arpeggios to BIG chords!

This is an idea I had in my head for some time, combining the 264t Polyphonic Adapter with ART and my two 259t with the 242t to trigger clusters of notes and create strums / arp / chords type sounds.

It worked and here is how!"
