I have a Coco 2 & PB2 and the other night I tried running the stereo out from PB2 into Coco but no matter what I did the Coco would just spit out a super distorted signal when freezing the buffers.

I tried at the highest clock speed and that didn’t help…

I tried the stereo in on the front of Coco as well as the “piezo” input for more gain control but no matter how low I kept the mixer volumes in PB2 (I rarely go above halfway at MAX volume per part in patches anyways) or the gain itself on the Coco inputs, it was still distorting.

Out of frustration I tried plugging my Easel into the Coco and got perfectly “clean” samples (as far as coco is concerned :sweat_smile:) which ruled out the buffers being broke or off…

Anyone have thoughts on this?

Did you try to plug PB straight into mixer? Just checking but you do know that there are two stereo inputs on the front of coco right? Did you try each of them?

#1110

Yeah it’s fine straight into a mixer & it’s also fine running through coco “dry”.

It’s only the sound that appears in the buffer that is appearing distorted, it’s really strange. I know many people have had issues with the buffers being “dirty” but that’s def not the case here because it works fine with everything else!

I do KNOW that there are 2 stereo inputs on the front of Coco but it’s a good point you bring up! I only tried the left one & the piezo. I’ll try the right one next time, thanks :+1::heart:

Hmm. Sorry to hear that. Please let us know if you figure it out!

Have you connected the two devices through the black grounding connection?

#1113

They were grounded to each other yup!

Should have mentioned that in the first post too, whoops :grimacing:

In my short time with my coco I find sometimes I experience this too @samule.edmoon. going out of my eurorack into the coco sometimes creates unbelievably distorted loops. Other times, very clean. Haven’t been able to quite figure out why. I feel like it’s more of a problem if I’m modulating the buffer, direction or skip when looping.

Yeah, same - I usually send the snare output (or dust) to the green coco inputs without issue, but the gongue outputs always sound distorted, even at super low gain levels. Will test a little later…

#1116

I can’t recall if I was doing this at the time or not but I don’t believe so.

I thought maybe it was just an impedance issue but it seems really strange to me that the dry “pre buffer” signal sounds fine :thinking:

The fact that I’m not alone gives me some comfort at least…

i’m considering getting a dunst, i already have a q rainbow 2 and giving the predominately underwhelming feelings towards this specific module on this thread i was hoping to hear some more opinions about it.

rebuilt my rollz to be a bit more predictable/interface-able and got @mlogger 's PCBs! here’s some experimenting with my rollz, an esoterica spikering, preamp, and anti preamp. the delay was made by a guy called orgeldream

also using a korg SQ 1 to sequence the spikering at points as i put in a CV input

does anyone have suggestions or schematics for power supplies for ciat lonbarde boxes? i’m building up one right now that is a whack of random circuits (4x rollz, esoterica, dogvoice, swoop spokes, chainlock, swoops, rando, preamp, and their anti versions, 2x gongs)

i’ve been powering my stuff with a 12v wallwart on a strip of wire and getting decent results but occasionally inconsistent

Finished (somewhat) these a while ago and thanks to isolation am finally getting around to sharing them.
I intended to make a full Rollz 5 but the local electronics store didn’t have the parts, so just have a rollzer and ultrasound filters for now but they sound GREAT and I’m a big fan of the Ciat Lonbarde workflow (which could be dangerous for my savings in the future). I could spend hours playing with these (much to my housemates disapproval).

Are those old VC tape cases? They look great!

#1124

Yeah they are! I forget where the idea came from, but when scrounging for a case it popped back in to mind and surprisingly they make quite a good DIY case!

So awesome… I want to learn how to build but I don’t know where to start. So impressed with everyone on this thread who is building.

#1126

I bought some of the paper circuits PCB’s off @mlogger and it was super easy!
Building the 3/4/5/6 rollz circuits are beautifully simple and super easy to make, yet create wonderful textures on their own.
I would put them as an essential DIY audio circuit to attempt even for (especially for) beginners.

Thanks for the heartening response! I’ll try those out! Are there instructions?

#1128

The circuits have icon-like representations for each of the components, and there’s an image file that is mentioned in this thread I believe that is a “key” to decode what they are.

Once you know which components are represented by which icon, it’s just simple placing and connecting everything! There’s also a Facebook group called Ciat Lonbarde Paper Circuits Troubleshooting that’s helpful as well.

I built one of these for my Rollz. It’s the power supply for the older kitten-nettik machines:

(scanned from the documents that came with them)

And for the physical power supply, the bugbrand ones are really great. (they are sold via Patch-Point, but I bought some directly from Tom)
