I might be missing a module since I'm rattling them off the top of my head. They're fairly easy builds with the exception of the 208's. The 208 is a pretty complex build. They all require a little bit of tweaking but sound great! Buchla is certainly a quirky system but really intuitive and inspiring to use.

The 248 MARF is a REALLY cool module to play around with. I haven't even scratched the surface with the possibilities, it's a really deep module. The low pass gates are also really unique sounding as well.

I also built a TTSH (ARP 2600 clone with a smaller panel) and am currently building a 'full size' ARP 2600. Fun stuff!
Here I go down a new rabbit hole for me.

This one looks interesting:

Am I correct that the Buchla oscillators use Volts/Hertz control as opposed to Moog Volts/Octave? Just curious as I delve into this. (No particular reason for asking. I am NOT a musician but enjoy learning new stuff!)

I've only built clones but they're all calibrated in Volts/Octave. The thing that different is that Buchla is typically 1.2V/Oct where Moog is 1V/Oct. Buchla can be setup for 1V/Oct, 1.2V/Oct and 2V/Oct.

The 296 module that you linked is one of the last modules on my list of Buchla modules to build. It looks like a lot of fun. It's also one of the more complex 'Buchla builds along with the 208.

Here's a cool run down of the 296.



and here's another video that uses the 296 (upper left) heavily and the 248 MARF (lower right) modules.

..and schematics for a bunch of the classic modules. Buchla schematics are pretty wild to look at. The schematics links for the 100 and 200 series are on the left of the page.
