LZX Status Update 6/25/2022

In Expedition series only, I would be very surprised if you get these specific three modules to work outside of NTSC/PAL timings:

  • Liquid TV

  • Visual Cortex

  • Navigator (X/Y positioning is likely fine but operating rotation without matched sync probably will give you at least a glitched line)

Everything else in Expedition that requires RCA sync should be able to sync to HD timings without a problem. If it doesn’t require sync, it just works in any of the timing formats.

LMH198x is what drives the Gen3 multi-format sync extraction but LM1881 sync extraction used throughout Expedition is surprisingly robust with HD timings. Different story for Visionary, Orion and Cadet modules.


Thank you for information. :blush:
I was also worried that the Expedition modules would be damaged by the HD workflow.
But the components and the circuits of the Expedition module seems to be strong.

Yes, this raises questions. So I’m also curious.

I love the Seetec monitor! It has CVBS & YPbPr inputs with loopthru (very handy if going to a recording/capture device afterwards) and supports all 15 of the Gen3 timing modes natively. There are a few versions, this is the rack mount one.

Contour is another 8HP utility module, following the same triple function layout as Keychain & Proc. The VC differentiator is the same architecture as Curtain’s, but uses only the high frequency range. Perfect for pulling edge gradients out of Keychain’s flat outputs. Or reversing that relationship, Contour into Keychain becomes an outline extractor with adjustable stroke width.

Keychain uses the very fast AD8564 quad comparator and looks very sharp in the HD modes.

We’ll be doing a multimode/2D VCF based on the DWO3 architecture and some sort of edge proc/luma enhancer later on. Contour and Keychain are meant to up the system’s ratio of base key/filter functions at a very high function-to-HP ratio (1 Filter/Key Gen per 2.67HP).


Oh, yes! I love all these filters and keyers. Thanks for the info.


Love to hear about some texture and filtering Gen3 options. I’m sort of curious if there is any preference for a Gen3 noise source being single dual or triple?


For a typical analog noise source, I think that one is probably enough. The idea of a noise source is to provide randomness across all frequencies at once – so you typically use filters to further shape the noise’s tone. So, I guess that’s my opinion: noise with different filtered outputs or noise with extra mult outs is probably more useful than a triple noise generator.


That’s kind of what I pictured for a noise source. the only reason to want more noise sources would be for chromatic noise, though you’d still want filtering for each channel.


Keychain is now available on the LZX site!


It was a busy week – the workshop built batches of the Keychain and Stairs modules as Jonah and I tackled a few ESG3/DSG3 issues that popped up with the progressive formats, and then focused on ESG3 QA/calibration. Today ended with around 40x ESG3 units calibrated and ready to go, and some of those are already in the mail.

I did manage to squeeze an easter egg mode into ESG3, because we had one position left on the 4-bit format select switch, it is 240p60 (262 lines/field NTSC progressive) – it should be a fun one to play with on some older CRTs. Currently my display will recognize it as NTSC on composite, but not on it’s YPbPr inputs.

Next week, we’ll get to review the latest DWO3 prototype, which was finished yesterday, and see if that module is ready for production as well. And I’ll be getting back to TBC2, which we’re hoping to get out the door shortly as well.


This is the motherfuckin future! (I wanted to write this in all caps but Discourse hates that.)


Super stoked for my esg3 :partying_face::vulcan_salute:
