Triple check this stuff
Yeah, that’s the part I keep going over…but nothing is jumping out at me.
I’m going to have to put the 'scope on it and see what’s going on. But…that may be more than I’m up for tonight. Little tricky due to my pack of power outlets and where my scope is compared to where the modular is. I’ve been meaning to build another power supply for my desk to help debug things…but I’d still need some longer patch cords to get a clock from the modular over to the desk then.
I should build something like the erika synths module tester or just a simple VCO/LFO/power box for testing things with. But…I don’t really have much desk space either for that matter 
Hmmm…looks clean. If I hadn’t already built two of these I would be worried about my pcbs. Really weird. I guess you could try a different resistor for that 2.7k or two in series. I don’t see why that would mess with it tho? But Im not sure

I have blue leds and 2.7K on both of mine and they work fine for every position of the switch.
At least they switch a constant voltage as expected, not yet tested with audio.

Double check that R12, your color code doesn’t look like 3k or 2.7k
Orange-orange-black-brown = 33r?
Orange-orange-black-silver-brown = 3r3?

Good eye. And an embarrassing mistake for me!
Not only did I grab a 3r3 instead of a 3.3k…I planned on using 3.3k because I didn’t have any 2.7k’s…but…I do have 2.7k’s…right next to the 3.3k’s in my sample book. Apparently two nights in a row I saw K’s where they didn’t exist 
I mean…it’s not like the labels are even hard to read or anything:
At least it will be an easy fix when I have a few minutes to break out the soldering iron!
Thanks for the second set of eyes. I probably would have figured it out when I swapped that for a different resistor anyway…but glad the error makes sense now!

Used a coffee/stretch break to fire up the iron and replace that resistor…
And it’s behaving as expected now 
Pretty hyped…I’ve wanted this module for awhile. Need to make some more power cables before I crank out any more modules - and will have to take some of the rails in my case apart to slip in more nuts since those k25’s are using more nuts per HP than I counted on when I put the case together
But with this guy in there now I’m feeling inspired to actually play with the modular this weekend instead of work on it for a change

Awesome! There’s so much cool stuff you can do with sequentials, honestly one of the most useful utilities in my opinion

I still have not quite wrapped my head around how they function, but I am looking forward to getting mine built - seems like a good complement to a clock divider.

Basically you have one jack that can be connected to 1 of the 4 others. It’s only connected to one of them at a time. Which one it’s connected to changes with each tick of the clock. if it’s in 2 mode then it just switches between the first two jacks each tick. If it’s in 3 mode then it cycles through the first 3 jacks, and if it’s in 4 mode then it cycles through all four.
So in full 4 mode it will start out with the common jack connected to the first jack. Then when the clock ticks it will switch and the common will be connected to the second jack. Next clock tick it will be connected to the 3rd jack, and next clock the 4th. After that it cycles back to the 1st jack.
The common can be output in which case the variable jacks are inputs and each clock tick changes which input is connected to the output. Or the common can be used as input and each clock tick changes which output is connected to the input.

Ahhhh. I believe I’m getting a mental picture of it now.
Should be fun when I get my big button up an running.

Is this correct? If so I need to swap mine around!
Whatchu talkin bout
lol 20 chars
Is the power header as you have it in the picture correct? I have the feeling I need to flip mine.
Might be good to sort it out before testing!

Yes, that’s the way I soldered mine and it works…

Apologies for going slightly off topic, but I could use a folder like that. My google-fu is week this morning, what’s it called and where did you get it from…?

Looks like @fredrik has a keyword. I really don’t know where to get one by itself…I got this resistor selection from Amazon and they came pre-sorted in the pages/binder like that.
