Mobenthey/Ciat-Lonbarde (synthmall) thread

Paper circuits are quite robust. It gets you where you want to go without too much fuss.

[wheelersounds]

Peter suggests printing out the circuit, cutting it out, folding it, and gluing it onto a piece of cardboard from a cereal box or something. You punch the holes out with a thumb tack or sewing needle, and fold the legs of the components in order to connect them. Folding the legs keeps them in place as well. I built the Lil Sidrassi this way and it works very well.
On the paper circuits site there are even photos where people have built this way and removed the paper after, pretty wild.

Thanks for listening!

I have no plans to put it on BandCamp unfortunately

Feel free to DM me your email and I can send over the WAV’s

Ah, taking the paper aspect a little less literally might help me then - mounting it on cardboard is sounds like a plan (has anyone used fabric?)

[wheelersounds]

@petesasqwax

has anyone used fabric?

Not that I’m aware of, but it should work if the fabric and adhesive aren’t conductive. A thicker fabric like canvas would probably provide more substance.
It might actually be interesting to tape the paper to a piece of fabric, build the circuit, and remove the paper leaving the fabric behind. Then it could be sewn/appliquéd to something.

Here’s a couple of videos of me playing my Sidrax through the Time Shadows pedal (thanks, Hype Thread…). I love this instrument so much.

Hmm, embed preview isn’t working… any tips on how to get it to show up here?

I made a little something today experimenting with my recently acquired Cocoquantus. I notice myself having a tendency to let things get out of control so for this I tried to keep things simple and just sample a few piano notes from the Yamaha Reface CP. I’m modulating amplitude (but not playback speed) as well as the flip and skip input of both buffers with the Quantussy.

would it be very difficult to add a cv out to an existing paper circuit build or a banana jack to cv converter for just a few outputs? or would the easiest thing just be to buy one of the meng qi brass format jumbler modules? is it possible to make a small version of that with the equivalent of a paper circuit or a few components? would there maybe be a build guide for something like that somehwere?

[crucFX]

Depends on which circuit you are referring to honestly.
Rollz can easily be dc coupled to send positive pulses.
I am sure others could be as well.
You can pull strict high freq. out from USF, and a solid Square Out from AVDogs.
I have used those for modulation.

I do not really understand what the second part of your question is in regards to. is there a specific paper circuit you are looking to build? - there are many…

[wheelersounds]

My take on this is rather simple – to give a paper circuit a eurorack-compatible output, solder the sleeve (outside conductor) of a Euro cable to any point on the paper circuit that is Ground. Solder the tip (inside conductor) to the output point you want.
If you have multiple outputs you want to use for CV, a format jumbler is a very easy thing to DIY. There are some examples here on the board, but if you have problems finding some I could draw you a schematic and build guide.
Either way, in principle the main thing is getting your circuits to share ground, and also making sure none of the output voltages are going to fry the inputs. This is somewhat challenging because different devices have different tolerances, so maybe have a search.
Hope that’s somewhat helpful!

[encephalitislethargi]

that’s exactly what i was looking for, thanks. i wasn’t sure if you could just give a paper circuit a cv out. sounds doable though, even though my knowledge is limited.

@crucFX about the paper circuits, i guess i was asking if someone made a diy type kit or something for this goal, sort of like your power board. but yeah i guess the idea that it would be a circuit is stupid. sorry about that

i have one where i combined two rollz 5’s (5&6 roll) with a spikering esoterica. so yeah, i would want to send out the rollz pulses for more organic chaotic cv triggers

[crucFX]

oh not stupid at all.
While I sell stuff, it is a little bit more geared towards those who fully dig the DIY vibe of circuits.

I would suggest you take a look at Meng Qi’s Rollz-5 board.
It has everything needed to get you started and is not a hard build!
There is a BOM out there for it I believe.
It doesnt come as a “full kit” but then again, most ciat-lonbarde stuff does not.

If you want to look at something pre-assembled to get the ciat jive - take a look at Ellitones Ultrarollz (if you can find one.)

If you want - I could probably make a “kit” or 2 for you?
Just a thought - most of us who convert and sell the PCB’s would probably be willing to work with you!!

[crucFX]

so for something basic like rollz - you can add the Positive out pulse by adding in a Resistor

This will make this output Positive Pulse only -
You can modify the original paper circuit with a pen/marker and some extra holes
No kit necessary

[encephalitislethargi]

i have built two apcs circuits and the 2 rollz + spikering i mentioned already. so i am familiar somewhat. I just wanted to add the cv to that 2 rollz spikering box i made. i probably will grab the meng qi rollz 5 eventually. that was the first thing that piqued my interest with ciat lonbarde and now i am finally experienced enough to build one.

i love the paper circuits, especially this last one i’ve built. it sounds amazing. but i have my sights on a plumbutter 2 or cocoquantus. probably coco. just need to figure out what i’m going to sell first. i was thinking i’d probably be ok getting rid of the nebulae, which is the only thing keeping me from ditching modular, if i had a cocoquantus

i have such a big list though. i feel like i’m going to be perpetually reconfiguring my setup and swapping out gear forever

*oh wow thanks a lot. i’ll probably have some questions once i actually dive in here but i am trying that for sure as soon as possible

[crucFX]

Oh Sure! So on a 2 roll - take a look at my version - I added an LED Driver and a Positive Out - (Technically makes it a 2 roll + 1 Positive Pulse out) But I do not consider it a 3-Roll as it behaves differently.
Hopefully this will help you modify your preexisting 2-Roll
High-Res Version

[encephalitislethargi]

im sorry, my writing is a jumbled mess. i meant to say that i have two rollz circuits (1 “5 roll” & 1 “6 roll”) inside a cigar box with a spikering circuit, all connected together. but i will probably be pm’ing you for details shortly. thanks again

My Fourses Tarp’s amplifier started picking up AM radio signals. lol

for people here who interface their cl gear with eurorack etc… what do you use all that stuff to do?

i’m trying to decide if i should stay in euro at all or go further down the cl rabbit hole, but there are some things in euro that i quite like using. i know pulse information won’t translate out of cl, so there goes my first idea - using rollz to clock things in euro land with meng qi brass (with pulse spike resistance) as an intermediary.

for reference, i have a pb… is there a reliable way to get sequenced pitches out of the various elements of pb? i can assume it’s not v/oct or anything, but i’ve seen some people here sequencing melodies from euro on cl items. it would be nice to have some more options for gentle tempo fluctuations out of the rollz 4s using in/verso. i’m just looking for some ideas!

what do y’all do?
