My build progress

Built a fixed filter bank module. It contains one band pass filter.

Okay, it will contain more filters. But I thought I’d build just one and test it before doing all the others.

After I found a boneheaded power connection error and fixed it by turning the TL074s around, it works.

DId you 3D-print the knobs? If so, would you be willing to share the STL-files?

There are not too many people who build a synthesizer at the age of 18. And it sounds great, so congratz!

Just finished my 4x Decay from Barton Musical Circuits.
Still need to add the TL074 and to test it.

Hi all,
I have started building a new synth. I really liked the idea of the moog mother 32 that you can fit within your eurorack setup so I decided to build the whole thing in a single panel. I know…
As much as I like the look of it so far, it is a massive pain in the a** to handle. But where would be the fun of it if it was straightforward.
So far, I have got a single VCO, a multiple, a wavefolder and a 3x VCA/mixer using the V2164. Next on the list are a dual envelope generator, Moritz Filter, a simple lfo and the 3xdelay module from lmnc.
( I am also adding a photo of my spaghetti recipe, all your modules here look so nice, I can’t be the only one that feel ashamed when looking back at mine)

Don’t worry, you’re not the only one :smiley:
My first modules use IDC cable spaghetti, snapped pencils, and hot glue. You will improve!

After a long delay with a lot of real life thingies finally I’ve found some time to finish my version of Sam’s 2700 Twin-T drummer. Just need to insert the ics and to test the hole thing in the hope not to release the magic smoke.
I’m very happy with the layout and the symmetrical design of my pcb :smiley:

This is what I am using:

The file can be opened with OpenSCAD and then you can tune all kinds of parameters and generate the STL file for slicing:

Great work, as always. Your sample sounds very cool, I think I will try this module too…
