LZX Gen3 Modular Releases 2021-2022

Yep, that’s the idea. Eventually the acronyms become synonymous with the function or device itself. Short acronyms are also common in the language of color and video in general: RGB, YUV, CVBS, CCIR, etc.

I would prefer plain metal or white panels for better legibility in the dark rooms where I often work

Since we have based our supply chain in FR4 panels, that means variants are easy to manage. So we don’t have some big investment cost/lead time involved in a variant. That means we can offer alternates as a customization option via our OEM store. White panels is probably the best sensible variant.

The design language of the dark panels is inspired by classic Ikegami and Sony CCUs:

All great thoughts, thank you for caring so much!

We had a discussion about this today. The one that is bugging us most is DSG vs ESG. “SG” is being used to describe different functions (Sync Generator vs Shape Generator). The other one I don’t like is SMX-3, as “MX” is being used for “matrix.”

ESG is a descendent from the Visionary series Video Sync Generator (VSG), so the rhyme helps the lineage there.

FKG likewise is a descendent from the Visionary series Triple Video Fader & Key Generator (TVFKG) so that is where it comes from.

DWO and ART I think are both good. It sounds like the first is a VCO of some kind, and the ART just makes me laugh. Hell yeah I make ART (Affine Ramps Transforms)!

DSG is also similar to the Serge DUSG (Dual Universal Slope Generator), so that could be confusing.

So we’re considering changing DSG-3 to DQG-3 – Dual Quadrilateral Generator, pronounced “DAWG THREE”. :slight_smile:

Awesome. Best way I can review is if you post a thread here with a screen shot of the schematic, with all reference designators readable, and number your questions in a list.

Yes. SMX-3 is an RGB matrix mixer. Unlike Color Chords though, this one has full polarizing controls and individual inputs for all 9 knobs. So it is a bit closer to the original Visionary series Video Blending Matrix. It is more minimal because I consider the “3X3 RGB Matrix” to be primitive and important graphics/video function. This module is the basic building block for YPbPr to RGB and RGB to YPbPr conversions in the utility sense, and “anything to anything” in the video art sense. :slight_smile:

that;s great @CreaterLars thanks!

looks like a tiptop mantis case will be able to hold and power 17 of these modules, then - with 4hp spare - or better yet half a dozen or so and probably the rest filled with expedition series - the negative rail was always the problem!

Interesting to see how the Foundation series has developed since the roadmap was posted. ART and DWO seem to fulfill some functions originally intended for the 8hp Verbs series?

Hope this isn’t too much of a tangent: how do the standalone instruments (I’m thinking of Solarium, Covidiot, and the (scrapped?) texture instrument) fit into gen 3? I’ve been fascinated by the whole Automata/Chrono series idea.

Could you explain how the new modules relate to the Expedition series in terms of resolution? I know Chromagnon can output higher digital resolutions. Do the old modules get upscaled at final output via Chromagnon? Or are other things going on before this point if you’re patching these back and forth with Expedition modules? I have a VC as my final out at the moment, and have all of Chromagnon’s functions in Expedition format, but it’d be nice to have an upscaling output.

I like the short functional names much better than the playful ones, which added to a steep learning curve for me, but I don’t like the black panels so much. White text on black is significantly less legible, especially in the kind of eye-strain flickering darkened room of most video artists.

Also, for pure aesthetics, there are so many eurorack black panels in music modules already, and the grey of Expedition really gave them their own identity as video modules, and recalled my own nostalgia for machines and devices that were those colours. I’d love distinctive-looking modules in Quantel Paintbox/Amiga Toaster beige, or which leant into the fonts, colours and aesthetics of 70s and 80s video mixers and VHS tape logos.

I think the names are the least important part of the modules, but since it’s being discussed, I fully agree with this post from @sean. ESG vs DSG is the main thing that was tripping me up, and I’m pretty sure it’s because they share 2 letters in the exact same spot yet those letters stand for different things.

From the first post and examining the module images, I was already pretty psyched. But then reading @creatorlars replies with more details about the various modules, I got even more psyched! I love the comfortable density of function!

re: DWO-3, am I correct in interpreting that the two oscillators to have independent (from each other) front-panel sync inputs? And does that mean one would therefore be able to sync them via the front panel to a Cadet system?

Well the SMX-3 sounds like what I’ve been looking for. Can’t wait! Thanks for the info Lars.

Yes and yes.

The frontpanel sync inputs are always active, too – on the range controls, when you are in the “HS” or “VS” modes, hsync and vsync are taken from the rear. These are combined with the frontpanel sync input. So for the first time, they are a “reset” input. In other words, you can be synced to hsync and still reset the VCO multiple times before the next hsync via the frontpanel jack.

There a number of behind the scenes improvements too. The A1 range for example is sampled & held at vsync, allowing for clean switching strobes.

Hey lars, I’m not sure If I saw any responses to the availability of these modules. Personally I don’t have much of a strong preference for whether they are available before or after chromagnon. Though having some new modules sooner would be cool. Will these be preorders or will they hit the LZX store when ready? I’m also curious how many will be available and what the production schedule will look like going forward with gen3? Im also wondering as well if there are any plans for a new liquid tv?

The way things evolved, we found that 12HP was the way to go as a base size, as it is also the minimum size for a module that has Sync IO in the rear (which all of these do, except for SMX-3).

So yes, ART is the first “verb”. It is designed to be chained so that you have transformations you can modulate in steps. It is the AFFINE TRANSFORM verb, and covers MOVE (X & Y knobs), SCALE (XX & YY knobs), SHEAR (XY & YX knobs).

The next verb would be MOTION based, and cover SCROLL & ROTATE/SPIN.

Another big thing that changed is that ART (and future verbs) have auto calibrating HV ramp generators integrated into them. So that means each verb is also a standalone shape/figure generator. When you patch into the HV inputs (the ones with the little icons) you are overriding the internal ramps.

DSG (Dual Shape Generator) is then an output function bank for the vectors created or modified by ART (or DWO). A typical patch could have a pair of ARTs patched into the HV inputs of a DSG to generate 2 shapes that are then “movable, shearable, and scaleable.”

Hope this isn’t too much of a tangent: how do the standalone instruments (I’m thinking of Solarium, Covidiot, and the (scrapped?) texture instrument) fit into gen 3? I’ve been fascinated by the whole Automata/Chrono series idea.

Different levels of abstraction is the main difference. Think of it like zooming in.

If we zoom all the way out in LZX land, we have instruments. Memory Palace, Chromagnon, and future Automata instruments. The instruments are like very complex patches with a performance interface, and cover some functional territory that would be prohibitive to try to patch on a modular system. And may include functions that just aren’t practical in a single module.

So think of the instruments like an Oberheim SEM voice or a monosynth. They encapsulate a complex but usable workflow, in a way that allows them to expanded like a polyphonic instrument (these comparisons only work if you are a music synth user too – so forgive me if I’m being obtuse.)

Now, we zoom one step further into LZX land, and we find that the functions in the instruments are composed of modules. Once we are done with Gen3 modular you should be able to patch up most of what Chromagnon and other instruments do. Modules have a different design priority – a system user can create a modular system that is more like building their own instrument with modules. So things like function density and a more straightforward approach to “1 primary function = 1 module”, and small modules you can use as building blocks is key here, as those goals empower the user to create whatever they want. With modular we are presuming you are buying several modules so you can design your own system. And there will be plenty of recipes and bundles we will offer for that, too.

Expedition series often combined multiple functions in one module. This was great within the scope of what we were trying to do – explore a world of new experimental ideas for video synth functions – but eventually a module gets so big that it makes more sense to include the holistic workflow (video input, video output, compositing) along with whatever primary function is involved.

For example, Visual Cortex – we did something right there, but it’s not really a “module” in the building block sense – it’s the first prototype for an instrument. Visual Cortex ultimately limits modular expansion in the sense that you cannot have multiple fader/compositor sections or multiple output encoders, or multiple ramps, without taking up a lot of space. War of the Ants, Fortress – also great examples of mini instruments.

So the idea in this gen3 era for us is to eliminate some redundancy and reorganize. It is a spring cleaning and update of all the circuitry. Things that were previously hybrid mini voices (like Fortress and War of the Ants and Cortex) will get expanded and made into full instruments. Things that were previously hybrid functions will get put on 12HP modules that encapsulate a functional step (like generating 2D waveforms, keying/compositing two RGB layers, etc).

We are trying to not be concerned with any market trends and just do what we feel like empowers the user best.

So with “LZX video synthesis” you really have a few options:

  1. Stick to the instruments like Chromagnon, and expand/patch between “voices.” Like a studio full of monosynths you are mixing.
  2. Use an instrument like Chromagnon as a “base station” and add modules to it as expander functions. For example, adding a DWO to Chromagnon is very useful!
  3. Go “pure modular” and roll your own instrument/studio/88 band colorizer, etc. In this case you’d want to start with ESG-3.

Please let me know if anyone has questions on this. This is a description of our core philosophy/approach right now – one which is ultimately hoped to benefit/empower the community!

Seems like it has a lot more in common with Color Video Encoder, especially as far the front panel feature set goes.

[quote=“creatorlars, post:95, topic:3397”] Each verb is also a standalone shape/figure generator. When you patch into the HV inputs you are overriding the internal ramps.
[/quote]

So they’re almost like a self-oscillating filter? They can modify an incoming shape, but also act as an oscillator? Do all the gen 3 modules have both processing and generating capabilities?

Very neat to consciously have semi-modular, hybrid, and fully modular workflows in mind. I can’t speak to market trends, but Chromagnon is my first step into video synth.

Do these correspond directly to Spritechild, Texture-Instrument, and Chromagnon, or are they examples of intermediary forms between module and instrument? WOTA as a full noise instrument sounds brilliant.

Just thinking out loud here so scroll on. I get you on the SG (sync gen vs. shape gen). I think “signal generator” because that is what we have it named in our routers at work. If there is still a debate, I would just called it ENC for Output ENCoder as that is the language you had on Visual Cortex. To my mind, sync gen is just a part of the RGB to Component/Composite conversion. That said, you can call it “Left Handed Shampoo Dispenser” and I’ll still buy a few.

Yep, it is both: CVE + VSG → ESG. We are trying not to use “Color” or “Video” in the acronyms, so it shortens perfectly. We don’t have separate modules for sync generator or video input/output any more – any input/decoder/TBC module or output/encoder module will also be capable of being a free running function (and distribute sync to other modules.)

Moving forward (and including Chromagnon and TBC2), anything generating a video output is also capable of generating its own sync and distributing that sync to other modules. So the ESG module is more like a “node”, that can operate independently or be synchronized to a parent node.

So the ESG is a generator in the sense that when you turn it on, it starts generating a video signal.

You’ve got the right idea. Think of it in graphics terms, like with the DSG-3 Dual Shape Generator. The “default” generator is basic HV Ramp Generator, AKA SCREEN COORDINATES. The shapes will be generated from the geometry of the video frame itself.

In other words, if you make a triangle with DSG-3 (without patching the inputs) it will be the same size as the screen. No input / ramp gen / oscillator required.

Now say you want to make the triangle bigger, or smaller, or reposition it on the screen.

You can do that by patching the outputs of an ART-3 to the DSG-3 inputs. Now when you turn the X & Y knobs, your output shape can move around and morph into different affine quadrilateral projections as you turn the knobs.

Now say you replace the H ramp input with a ramp out from a DWO Dual Wideband Oscillator instead. Now you have not just one triangle, but a variable number of tiled repetitions of a triangle pattern. The DSG-3 is using the ramp waveshape from the oscillator instead of it’s local screen coordinates as it’s base.

Now say you want to sequence it so that your shape gets bigger and slides to the right, then gets smaller and slides to the left. You chain up another ART-3 in series with the first one, and mult the triangle out from your unused DWO-3 oscillator to the TRANSFORM CV inputs on both ART-3 modules. You adjust so that when one transform is active, the other is muted, and the two bounce back and forth across the settings on the two ART-3 modules. You program in settings on both sides as desired, and you get a 2-phase morph.

The key point of this workflow is that you are using something simple – a single ramp LFO – to transition between two groups of settings. It is like a marionette, where only a few strings may control many joints in the puppet.

If you allow some breathing room between transformation depths, you get spaces in the movement where both transformations are fully attenuated – so now your shape morphs back and forth between the original screen coordinates and two different sets of transform settings.

So by the time you have a couple pairs of oscillators and transforms, you can get into a level of programmability that can be difficult when not approached in this step-by-step transform + output function (shape generator) type of workflow.

Anything on the roadmap is just a code name for an evolving R&D project, not necessarily a product plan. They are themes in our development flow, areas we have identified that we plan to go. So as you can see how the Verbs/Foundations concepts evolved into where we’ve arrived at in the OP, all of the other instrument concepts will likewise be evolving concepts until we arrive at a conclusion on product identity.

Thru the first few Automata instruments we will likely be looking for “places for the Expedition to land.” Chromagnon is one such place, and consolidates the vision of modules like Navigator and Shapechanger.

The luma/texture instrument will consolidate the vision of modules like War of the Ants and Prismatic Ray, various filter modules over the years. It’s the “raw texture synthesis” module.

The Solarium/RGB instrument – it will be consolidating the vision of modules like Marble Index and Visual Cortex – also it could be considered the LZX video mixer (two external sources).

That’s just the loose plan. We won’t be working on any new Automata instrument designs until we’ve completed all our current projects with Chromagnon/and get Memory Palace/TBC2 shipped and into regular production.

Nitpicking aside, I really do like the overall concept here, separating functionality out into more discrete blocks.

And for what it’s worth, my initial reactions to each are the following:

FKG: Nice. A little sad not to have the separate key outs from the OG Triple Fader, but a fine tradeoff for the much trimmer package. Don’t really need it myself, as I already have three mixing modules, but could possibly see swapping out one for it.

SMX: This is the only one where I feel a little bit that the price perhaps exceeds the functionality…? But given that others are the inverse, where it seems like you are getting relatively a lot for one’s money, all’s fair. But, yeah, probably already have this functionality covered in my system, personally.

ART & DSG: These are the kind of modules that don’t quite feel like they were built for me and my workflow (I am more into image manipulation than shape generation per se) — but also, precisely because of that, their functionality are a hole in my current setup and could probably be very interesting to “misuse.” Awaiting demos to help me fully grok the possibilities.

DWO: Love it. Love two oscillators in small package. Love separate sync and sync reset functionality. Love the density of outputs. This is probably the one of the bunch that feels like it is almost exactly what I wish it would be. Now, not sure more oscillators are what I need either, but could again certainly envision swapping out one/some currently held modules for one of these.

ESG: Have been interested in integrating a second output encoder into my system, but maybe realistically just want a more stripped-down, 4hp one (hoping maybe revised Cadet includes a 4hp component encoder??). …I too am tempted by HD. But, I dunno, the 80s/90s kid in me sort of prefers the low res SD flavor.

Edit:

You have just made me 1000% more interested in the possibilities of HD.
