Been really enjoying this 12u setup as of late..... most recent addition is a custom 275r Dual EQ/Reverb - tanks are external..... pair this with the 277r delay .... in audio heaven :)

beautiful Adam, looks like a perfect 12U system. I have been thinking about 12U lately. how do you like that 275r?

nevermind I just saw your video of it! :tu:

I have 6 other modules in the same look/format for this suitcase i'm building to start playing out with.... Low Gain aka Logan just finished wiring this all up and building for me today so I had to share!

Love the symmetry on that panel. Uber intuitive.

Gotta get some knobs for some of those! Seriously awesome though! Interesting touch controller as well!

How do you like that handheld scope? Have seen them around but never in person...

Haha those 281s actually were built for another wiggler. So I have to ship them :sadbanana:

Those scopes are awful but handy when I want to monitor something without getting my bench 'scope from the lab.

292 with knobs instead of 'nanas on the CV inputs and 'nanas on the bottom as well?

Those knobs add resonance to the 292. Please don't tell the elders.

that's a nice case too. and I'm jealous of that flopsequencer. I did something wrong and mine didn't work :cry:

Thanks guys. It's soooo far from being done. My backlog is still huge.

@ ws That's too bad about your flop. It's a pretty straight forward circuit, just a good deal of panel wiring and sensitive CMOS. If you start a thread about it we can get it working.

Here is a pic of "some" of my Buchla-clone modules. (Sorry about the quality of the pic.) The cabinet, which is a modular-type design is only half finished, but I hope to have the entire 30-space cabinet finished by late summer or early fall.

Hot damn. Now there's a clone system for ya!

What are the two modules on the bottom row that aren't the 257 and 259?

That's a very impressive collection of modules and the cabinet is top-notch. Very nice!

I'd especially like to know more about your touch controller. The absence of pots implies it is pre-tuned to an equal temperament scale. Do the blue banana jacks correspond to Pressure CV outputs for each key?

Did you design the entire touch controller yourself?

Are you talking about my system??? The modules on the right side of the bottom row are a 259 and a 291 Dual VC-BPF. (The 257 is located in the middle row.)

As for the other 2 modules on the bottom row, the module located at the far left end is "a functional clone" of an 8-step Buchla 245 (minus the clock section). The module to its right (2nd module from the left) is a module that I designed myself. It is a cross-between the VC-clock section of a Buchla 245 and a Pendulum Ratchet module. It also contains 4 logic gates. (I posted a close-up of this module a few days ago in this same thread.)

The 245-clone is actually a modified version of Ken Stone's Programmer/Sequencer. Modifications include toggle switches that allow one to skip specific steps (like the toggle switches on the 245). I also made changes to the input and output buffers so the levels are Buchla compatible.

This 245-clone also contains a special PCB that I designed and built myself. This PCB allows the sequencer to accept an analog input (just like the Buchla 245/246). Thus, one can hook this CV input to the output of a Buchla 266 and make the sequencer jump from step to step in a random manner (such as step 2 to step 4 to step 5 to step 1). One can also hook the CV input of this sequencer to the triangle wave output of a 281. This will make the sequencer ping pong back and forth. The number of steps, which can vary between 2 and 8, depends upon the voltages that are applied to this CV input.

In addition to duplicating the functionality of a Buchla 245, this module this module can also do some things that the 245 cannot do. For example, like the original CGS Programmer/Sequencer, it can be used as a programmer.

I also have plans to build a clone of the Buchla 246. This time I will include a clock section so I can make the module look exactly like a Buchla 246.

Yup, that's it. I didn't design the circuit. It's a CGS TRK.

@ tarissuoc
I remember that thread. It seems like it was so long ago?
In fact, I remember teetering back and forth on whether to buy a couple of sets of those touch pad PCBs. Once I finally made up my mind to buy a couple of them, I discovered that I had missed the deadline by a few days. After seeing Valis' finished product, I now regret it. :cry:
valis wrote:Yup, that's it. I didn't design the circuit. It's a CGS TRK.
This is great news. I had wondered if these Buchla style touch pads would work with CGS TRK PCBs. (I was afraid that there may be a capacitance matching issue.) I almost bought a set of CGS TRK PCBs when they first came out, but I don't really like the looks of those red CGS touch pads and they don't resemble anything that Serge or Buchla ever made. Maybe Ken will redesign them to look more like the Buchla touch pads (CGS86) or at least the touch pads on the Serge TRK.

On the plus side, I recently ordered a touch pad keyboard kit from jeroen baars. Too pad he didn't opt for a 16-pad version since I could have used it to build a functional clone of the Buchla 112. (Jeroen's kit only has 12 touch pads.)
