I made a video about the cool things we can do with the LZX Proc module.
Hopefully there will be more down the road. DSG3 was going to be the first one I produced, but my brain is still processing all the epic stuff I want to show off with DSG3.
These modules are deceptively simple to look at, but once I start working with them, I appreciate their power and versatility.
I’m still learning, and will never stop. Feedback is always welcome.
This is a really thorough rundown of Proc and the core use cases of a triple 1x gain attenuverter + bias + unity gain summing amplifier in video synthesis.
I’d add that for scan processing techniques with vector monitors, Proc is an excellent way to constrain your raster from H/V ramp inputs and center them as well as fine tuning the contrast / brightness fed into your Z input. With the unity gain summing inputs (A), that gives you an opportunity to patch in heavily attenuated DC offsets to the A inputs for additional fine tune control.
Nicely produced contribution to the community, thanks for putting the time into it. Hope you consider doing more in this style.
THIS IS SO FUCKING GOOD! Thank you Dr. Yo!
Awesome job Doc!! What a gift to the community. It’s so great to get more voices in a teaching role, and especially when it comes down to core voltage processing.
One point – you can get amplification over 1X with Proc, with some patch tricks and multing. For example, by patching the same input to both A & B, your gain range is now 0X to 2X (+/-n from attenuverter). If you cascade channels in combination with this, a gain of up to 8X is possible. It’s not the most efficient use of the module, but it’s a trick I’ve used plenty of times.
Fantastic work! Keep’em coming!!
Hadn’t thought of doubling the same signal to both A and B … of course that relies on another buffered mult
Yeah! Someday I may do some videos about raster manipulation. I’ve done some cool experiments with Foxing Hour Access and BSO Crossfade. But I’m really just a novice at that.
Yes, definitely in the category of “tricks you can do with the patch” rather than what I’d consider a feature of the module itself.
New videoheadroom.systems crossfade just came in the mail!
Oh cool, a luminance output, too. Always useful.
Loved the depth and detail of this. Bavo! I hope you do more modules.
Sidenote, I realized that for me TBC2 will be a fantastic learning tool. As a guy who has yet to have clips in the system, This showed me that working with basic functions like PROC can be a little more complicated to look at vs images from “real life”. My ape brain will have a much easier time comprehending processing to a photo!
Thanks! I think a photograph from real life is the best source material for demonstrating something like this. It’s not everyone’s “cup of tea” artistically … many people prefer to work with patterns generated directly by the synthesizer. But generated imagery is so abstract that it doesn’t always give an intuitive sense of what the synthesizer is doing to a signal. With a naturalistic source image, we can leverage the innate processing capabilities of the brain. And if it’s not moving, but just a still image, we can better perceive the effects of adding animation, e.g. the Baja modulation in the Proc video.
Really looking forward to TBC2 for a long list of reasons, one of them being the still store function. Currently I’m using a cheap TV tuner that has media playback capabilities, but it’s clunky. I guess TBC2 has sequential still playback? So we can play very short clips?
Now I’m off to watch the Johnny Woods video on TBC2…
Preach Doctor. FUCKKIN PREAAAACHHH!!!11
