Can we get a little taste? This looks fantastic.

But I haven't even done demos for the last batch of modules yet! :waah:

Will be able to get to all that soon though.

Whoa, this is in the works? Sooo tempted to start an LZX skiff!

Here's an image for the thread. I can at least answer questions. This project started out as a Sandin Amplitude Classifier clone but ended up evolving/redesigned into something much more.

Faders! Really like how this is evolving!

I have no real idea what video quantization is, but I suspect this will be a nice complement to the 4ms PAG. So would that little black spot below the clock label be a tap tempo button by any chance?

While you could do low frequency sequencing with this module, that's probably the least interesting use-case.

Quantizing is the process of splitting an image into 8 separate amplitude-based key signals. These key signals then control 8 VCAs, each of which has its own input/output and input bias knob.

The sequencer feature comes in with a separate counter that is value-added to the currently active key. So the current key value is between 0 and 7, and the counter counts 0 to 7. So if the current amplitude key is at 4, and the counter is at 7, then the third VCA is the active one (the value wraps around.) If you feed a video image into the quantizer/classifier portion, and an LFO into the sequencer clock input, you get an image split into 8 different bands, with the bands shifting positions with each clock pulse.

The button is just a clock button so you can click thru all the sequence stage settings.

With the Sum In and Sum Out jacks you can use it like a 1-to-8 or 8-to-1 sequential switch, or 8 individual VCA switches, etc.

Since all of the above happens at pixel/video rate, you can generate very complex colorized images that are a product of a video source and some sort of pattern source or animation clock. You can also of course modulate the top and bottom thresholds between which the 8 levels of quantization happen.

Damn! You crazy!
That sounds amazing. So excited to grab this one.

this one's gonna be a real game changer. For small and large systems alike. This plus a CSM will be an incredibly powerful colorizer.

Does anyone have any interesting patch tips for this one?

I tend to use it in what I assume is the standard way,
and I'm trying to think of how to make more use of the individual stage outputs.

This is my go to module for playing live because it gives you tons of options. The video below was made by plugging a premixed shape (brownshoesonly mixer the best) into the sum and modifying it using an LFO into the top CV and some other waveforms into bottom CV Some tips I could give on it off the top of my head

Patch an un-keyed shape into the sum and take the sum output, this is the basic way to use it
Individual patterns into each stage
Individual waveforms into different stages
Vertical bars into top CV, Horizontal bars into bottom CV
Throw an LFO or something into the reset when you have a shape plugged in to get some cool color changing effects
Mix different inputs into the sum and class
Try feedbacking stages into each other

This module is super useful for filling up space on a screen so I use it all the time live. Like all things LZX it takes some pre-mixing with modules or post mixing to do some even crazier stuff. I havent run live video through it before, I usually put shapes into it. LMK if you have any specific questions

Hey Sam, just came across this while doing a bit of research. Bloody awesome, thanks for the tips.
Cheers,

I've had this module for a few months and I've gotten some cool results , but somehow I missed this awesome thread !! Now back to experimentations-- let the weirdness begin !!! :bop:

That's awesome SamN.

Thanks for the post and video example.

Awesome video Sam. The question I have is the sequencer going to be released again or redesigned? Does expedition replace visionary? Apologies for side tracking.
