It's electronics, but not as we know it Jim.

Came across these rather odd synth's made by this chap, won't even try and pronounce his name, see - https://ciat-lonbarde.net/ he has a rather "unique" way of drawing schematics, see attached.

Mix of Doodle and Heath Robinson.
Interesting.

He must have studied this: https://xkcd.com/730/

I tried building that.

These remind me of art rather than electronics. With the first diagrams above I am reminded of bodies. I have not looked further as to whether they would work but obviously the layout would make it hard work. I have been thinking about how to combine my art and electronics so anything such as this can give inspiration.

The main point of circuit diagrams is to aid the designers and maintainers of the equipment. Tektronix, in the good old days, were at the very top of that game. By contrast the Melford monitors I'm working on at the moment have very poor diagrams. The ones in the OP are just weird. They may be art but they can hardly aid somebody trying to build or maintain the equipment.

Some Grundig and Philips were good 1950s to 1970. The 1930s USA radio schematics much harder to read than British or European of the same era.

An OS map is also much more use than a Fantasy style map with pretty mountains and castles.

Think these "schematics" are more for showing how cool & hip the designer is, from what I can glean these synth's use the LM13700 and there doesn't seem to be anything out of the ordinary going on.

I always struggle with the USA valve schematics with the HT+ not at the top
