ivebeen working on this very thing though i wanted to try to add it to a standalone bunch of rolls and obviously ran into attenuverter issues

[encephalitislethargi]

& @crucFX alright, i’m about to actually try this. i should have everything i need leftover from old tayda orders.

so i have the rollz5 5-roll and rollz5 6-roll grounded together with the spikering esoterica circuit. the connections i make between the rollz output nodes and the spikering node(s) are done with the banana jacks on top. i want to be able to send the resulting output of the rollz connections to the cv out. is that possible? which contact point/output should i be connecting to this jack to in that case? or would it just be easier to send one of the output nodes (cross symbol) from one of the rollz circuits to the jack?

also, since i have no idea how this actually works .with this jack pictured below, i would be connecting the bottom contact to the shared ground for all of my circuits. then with one of the contact pins on the right side of the jack, solder to the output node of the rollz circuit? would anyone be able to specify which parts im soldering on this thing?

and then, to insure that it’s only positive voltage out, i should add a 10k resistor between the output node on the rollz circuit and the jack, correct?

[hawksquill]

can anyone confirm that i can use the PSU i use for my c-l instruments with stuber? i assume so but can’t find any specs for DDD on the site.

[Justmat]

you can indeed! +20 characters

it’s not just from the output node for dc coupling. it is actually dc coupled to the collector on the transistor - (the other 2 points connecting to the collector are the 22k and the hairy cap.
I posted a modified 4 roll above.
or here it is again - follow the traces… the cross nodes connect to the base of the transistors.

In regards to utilizing a standard jack - make sure to connect the ground to a ground point (the flat side on an obelisk is the ground - the pointed side is the positive)
and then run the signal (after dc coupling with the resistor) to the tip of the jack socket and there you go

A little Saturday early evening session with my Fourses in the Zi Hai and Shnth. Shnth patch is Vuttpipe from @wednesdayayay ‘s always amazing Pillow fight. Recorded on my phone so audio is not the best but I plan on recording this and other variants properly soon for a new group of songs (is that an album?) to be put up on bandcamp.

holy smokes what a machine

Some pics of a recent batch of builds:
Ye Olde-Style Fourses Tarp (Bob Drake pcb)
Dogscratch (crucFX pcb)
DDDmkii (MQ)

Really want to post audio of the Fourses cuz it shreds, but all i have is a garbage cellphone camera, so it’s eyeballs only this time.

[crucFX]

whoa! That is super cool!!!
These are phenomenal

Some DOGVOICE for ya - It gets fun when I actually stop using the rollz and just let Dogvoice and the conrad papers do their thing

Long time listener, first time caller.

Hey there, Ciat Lonbardos… I’ve been hesitant to post here, as admitting how new I am to the work of Peter B in a room of highly active participants is a bit daunting. But, considering that in just a few months, I’ve converted and fabricated nearly every Paper Circuit into PCBs, I feel like I may have fallen just as far down the rabbit hole as anyone else. So… hello!

I recently finished a PCB conversion for Fourses Tarp, as I’ve been anxious to build one. I still have to double check my work for errors, but before I dive in, I figured I’d ask if anyone has any definitive information regarding the untraced 10K resistor in the upper left oscillator (highlighted in the second image). I can’t seem to figure out if it’s supposed to go to ground, or if it’s supposed to tap another node… the information I’ve gathered from within this forum are inconclusive (at least, in my limited understanding). Can anyone that has successfully built one of these provide me with some insight?

I appreciate anyone willing to share the knowledge.

[bunkerspreckles]

I do believe that it does go to ground, this is how I wired mine, anyhow, based on advice from a MW thread.

[crucFX]

You can add an extra extensive squiggler like you have in that second pic.

See the Teal traces - and red 100k resistor.

Or - as others mentioned. you can wire it to ground

[hawksquill]

figured i’d post a Stuber report in case anyone is looking for more general impressions like i was before taking the plunge two weeks ago.

i can see why it is so well loved among long-standing c-l users. it’s basically exactly what i wanted from a “peter blasser filterbank” in that it REALLY chews up audio in a seemingly limitless way and rewards lengthy periods of spelunking to find new vistas.

i listened to a short arp of a rhodes sample from op1 for about 2 hours the other night while patching and making adjustments. the lack of standardized colors for the bananas actually makes sense with this instrument imo and i already feel like i’ve made a mental map of which rows of bananas (seem) to do what. some seem best for affecting resonance, some for audio-rate, some are spitting out strange cv. the rungler with reset button is ingenious.

so yeah it’s probably the coolest filter i’ve ever used (certainly the most unique) and it sounds really great too, a bit juicier than other c-l stuff.

i’m really happy with it!

[bunkerspreckles]

Hmm, cool, now i wanna try that xtra squiggler bit, - my fourses has an unused brasso already on the panel bc i counted incorrectly when drilling yay! It sounds and operates nicely with the 10k going to ground, but I’m wondering how much/what changes when doing the mod in yr pic. Seems too easy not to try it and would be cool to get all the pegs active.

[ovumhum]

Thanks for the feedback, and super handy diagram! I think I might fab this board with both options. Choose Your Own Adventure… to node, or not to node? I may be off my rocker here, but a break out to either option via a jumper wire makes sense. Good call on the additional 100K resistor into the 4066. I’m not entirely confident I would have done it this way, despite three identical routing examples staring me in the face.

Also, thanks for the grounding confirmation @bunkerspreckles. I’m excited to hear that someone had a successful build using this info. Can’t wait to button one up for myself… thing sounds so intense.

Was able to connect a dc coupled pulse out from the rollz5 5 roll from my little spikering box. This isn’t a great example but it has the audio from the bandpass out going into the lpg and the pulse cv out to the eg for the lpg. I’m already getting a lot of great organic evolving trigger patterns with it.

Thanks for the help @crucFX

I connected the jack to just the one rollz circuit and it seems like the resulting pulse out I’m getting is the sum of the 3 circuits interacting. So I wonder if adding another output to the 6 roll circuit would give me different triggers

Hey folks,

I recently acquired a plumbutter 2 in a trade. I’m really loving it so far, but struggling slightly to get both audio out of it and ground it so I can interface it with existing gear. Hoping to get a sense of whether or not this is: 1- just my unit; 2- I’m doing something wrong; 3- it’s normal for a pb.

My setup is:

• run audio out via the stereo out jack. I use a splitter that goes from stereo 1/8th inch to dual mono 1/4 inch. This plugs directly into my audio interface.
• run a banana out of ground to a chain of other grounded devices (two buchla boats; one format jumbler; one Serge PSU)

Issue(s) I’m encountering:

• when powering the unit via PSU, if I plug a cable into the ground input, it stops working. This means: no lights going on it; no audio coming out of the stereo out.
• when powering the unit via battery, if I plug a cable into the ground input, the outcome is slightly better but still not sufficient: while the unit appears to be working still inasmuch as I see lights flashing, etc, I get no audio out of it via the stereo out.

When I power the unit via battery and ground it, I can get audio out via the white bananas and run those through a jumbler to a euro mixer and run it from there to my audio interface (this has a very high noise floor though compared to the audio from the stereo out).

So I guess specifically my questions are:

1. How do y’all get audio out of your pb2s, and do you interface with other gear?
2. Has anyone encountered a similar issue before, or is it worth reaching out to Peter to see if it warrants a fix? (This is a Peter build, I believe.)

(Final note as well: my ideal setup, which is running audio out of the pb2 directly to the interface and grounding it with my other gear for CV control is exactly what I’d done with a coco, so part of why I expected it to “just work”.)

Thanks for any input y’all might have!

Is anything else patched to the pb to modulate it? Anything else patched out from pb to modulate other devices?
