Patch dissection

perhaps a little more than just sharing video output I’d like to see people discussing/dissecting their patches

with the graphviz extension working on scanlines now things are about to get very interesting

So I’ll start out with a painting tutorial video using the LZX memory palace

here is a little flow chart using graphviz showing the basic setup


and here is a video going over the ideas behind the patch
this was essentially the same patch we used for of Vidicon presentation this year (a prismatic ray was used to modulate the threshold of the doorway additionally)

lets break things down

Here is a patch backbone we have only recently (the past week?) had the equipment to build that has granted access to a lot of really incredible feedback hyperplanes.

The idea is kind of to mix between several different “taps” of the same feedback loop. Each feedback path is using some kind of obstruction to inject information into the loop:

  • the key from the Memory Palace, either in warp or paint mode.
  • putting one or more synthesized patterns into the foreground layers of Color Chords, so they lie “on top of”† the VC expander -> Color Chords background feedback image
  • physical objects / optical filters / other stuff in the camera feedback path. This one we have not really even begun to explore yet.
  • wipes between channels with the MX50 itself. The MX50 effects can do a ton of work in this patch, I’m especially fond of compression wipes and the Multi screen tiling.

†"You can not refer to image planes as in front of or behind, etc., that is just an illusory human perception. The Cathode Ray Tube knows nothing of this, I can prove it to you.” –Dan Sandin

I think it would be a great idea (for me personally and for the community at large) to go through the LZX 3 patch series and add some patch visualizations.

My goal would be eventually to spiral bind and laminate them for a physical LZX patch book

I’ll be adding pictures and more patches as I go :slight_smile:

thank you so much!

I have a page in my patch notebook that is dedicated to recur setups that I love. I’m excited to get this kind of setup mapped as well
