german
i should have asked first, i see. although MULTIPLE is a compromise due to the space i had for the writing. Amplitude seems german enough to me, although your suggestions are better. i think i will change that.

One of my first contributions here! I've been building kits in Eurorack format, and slowly designing my own circuits. My goal is to have my whole system DIY.
Here's a few from Barton Musical Circuits.
Thanks for all of your inspiration and help and an awesome community!

Latest addition: a module I've called Second String. Basically an 8 step sequencer with three separate outputs, each step of which is independently controllable to put out between 0 and 16 semi-tones of CV. Intended to allow chords to be built using 3 or 4 VCOs (one to supply the root note, either 2 or 3 for the notes of the chords). Alternatively, one output can control a separate VCO, eg as a bass, in the attached sample.
Rats nest of wiring as you can see. And as for the panel - that's 24 4-way DIP switches, and 96 resistors!

That's a pretty neat idea!
I'm frightened to ask how long wiring it up must have taken, though

A fair few hours
Actually, debugging was the worst part. All those resistors and wires soldered to a small piece of stripboard = plenty of opportunity for shorts. Also, I had some msyterious errors in voltages which I finally tracked down to the residue from the no-clean solder, forming a resistance in parallel with my supposedly matched 100k's.
Also sduck your panels looks amazing.
I think I'll start using FPE to make custom panels.
Thanks! Yes, I like FPE, after getting over the learning curve part of their design program. Kind of expensive, but the results are great, so it's worth it.
Haven't checked in here in a while, and forgot to post this here -
this new build has 2 x 258 VCO's ,TZERO VCO from Electronotes ,Serge VCS ,2 x LFO's , MFOS VCA x 2, ARP VCF , Analog Neuron ,Mixer , Roland 100M ADSR ,Portamento and lot of wires ,happy with how it turned out ,the colorful panel pic is photoshop

Thanks ,i'm happy with this build overall ,could have picked other wood material for the case maybe ,audio i have some but i gotta say poor quality from my cheap souncard ,some noise in the back, i'm posting it anyay ,these are the buchla 258's ,in tune ,and some other patch ,btw using a 208 Random just to play a seq ,this box is missing a s/h for sure ..btw made some great glithy patches but the soundcard is so bad didn't dare to record , the neuron has anextra input and the mixer has 3 outputs for lot of feedback crazyness
Thanks Phobos i enjoyed making it .Muied Lumens i didn't had the chance really to explore it's sounds well ,i think it is capable ,but you can hear the recordings are noisy and i also think missing a lot of detail ,anyway ...what's next to build _________________ http://synthacks.blogspot.com/ шематикс

So, what did you spend your weekend on?
The synthcube box arrived Friday, and I got a case of the enthusiasms.
Some problems arose.
One, Gate Bus 3 didn't work. A bit of time with the multimeter and the cable charts from the original build doc, and I found that stabbing one of the crimped connectors hard with a screwdriver fixed it.
Two, 4 Oct won't bloody calibrate. Oh well, I don't care. I'll use the variable range for that.
Three... my ghetto diy case has now run out of room
