just going through your diagram and the CB one, they are a little different. Not to worry. The swirly bit on the original diagram is he inferring that this is an oscillator do you think?

Sounds like robots playing basketball, nice :slight_smile:

Normally on CL schematics the swirly bit refers to what Peter calls “MIDO” This is a virtual ground at 1/2 the supply voltage. It’s a way of using op-amps with a unipolar power supply.

Just drawn a 4-roll in Eagle. And the first thing I have seen is that you could add a cv input instead of using the potentiometer. In theory creating a feedback loop. Might be able to use another roll and the pulses would increase and decrease the tempo. Could be a little wild.

I’m going to breadboard the circuit to see if it works, then take it from their. Just waiting for some IC’s for the dogvoice first.

Another question about DDDM2. If I want to run it from a 9v battery, how to I connect it to the DC005 pins? Don’t want to get the wrong polarity and lunch the board.

“finished” with my summer project: a bunch of paper circuits and some format jumblers under one roof!
circuits are 3, 4, 5, & 6 rollz, gongs, ultrasound filters, av dog, rando, swoop, dogvoice, and gerassic organ. the sounds are very wild - primitive and organic and fuzzy. i’m really into it. it sounds absolutely bonkers through my eventide pitchfactor - i’m playing a show next month and i think that’s going to be my entire setup.

noob question about the CQ: what is the longest sample length and how do I set it?

#788

The loop/sample length is always the same, but you can play it really slowly for longer recording time. The trade off is sound quality. Just turn Speed down :slight_smile: not sure what the maximum time is.

thx :slight_smile:
just got it and only had a few hours to fiddle with it. seems interesting, but at this moment I dont really know what I’m doing…

for example, when taking samples I got gaps in the loop, even though the input was concistent. :thinking:

when/where are you playing next month (in chicago I assume)? I’ll try to make it.

Like digital silence? Try flipping the dolby switches to the center position.

can’t figure out how to link the exact post, but here is a quote from a muffs thread where user thresholdpeople explains the dolby switches.

“The switches in each Coco are the Dolby switches. The left switch is the Dolby for Input, right switch is the Feedback Dolby. In the center position they don’t do anything. In the up position they apply a ‘noise’ filtering compression, based on dolby noise reduction in tape players, basically blocking out any part of the signal below a certain threshold, to their respective input. In the bottom position they block the signal entirely at the respective input if there is a signal present at the other. So, for example, with Input and Feedback levels both up, and the Coco circulating material through it’s buffer, if the Feedback’s Dolby switch is in the down position, and Input Dolby is centered, you will only hear the Feedback output when there is no signal coming into the Input.”

After spending about two years with and on Eurorack I recently became interested in CL instruments. Currently I’m torn between Cocoquantus 2 and Plumbutter 2. I read a lot and watched a lot of videos and I think I have a pretty clear understanding of the concept, sound characteristics, pros and cons of the Cocoquantus 2.

Plumbutter 2 is still a mystery to me though. A lot of CL users are suggesting Plumbutter 2 as first CL instrument and almost all of the people who own one are super happy with it. The sound examples and videos I found didn’t convince me entirely though – and the sound palette seems a bit limited. Of course that’s a matter of taste and personal preferences, but my gut feeling is that there’s more to it.

Someone called it a “soft beat machine”, which sounds appealing to me. I’m not very interested in standard drum sounds, more in woody, clicky and pulsing polyrhythms. I think the Plumbutter 2 could do that, but most sound demos I found are more like “alien transmissions” (that’s how someone on MW described it).

So are warmer, softer, woodier sounds hard to find on the Plumbutter? Why do you love yours? Is it about generating unconventional wonky “beats” or about specific sounds – or something else? Perhaps you can point me to some examples?

I have a couple youtube videos which show basic PB rhythm but I am unable to link. Titles in bold so you can search.

Here is a basic beat which shows the typical raw generator sounds of the PB. Modulated gongue, warbling avdog, MWRS snare/hat. They are not very flexible when used simply as shown here.
Plumbutter 2 - Stupid avDogs

This one uses the fourth basic generator sound for the beat: rolls into ultrasound. Use headphones to hear the subsonic gongue bass note.
Ciat-Lonbarde and Lyra-8 in dub

More advanced PB playing is to find patches which progress from these basic sounds. Alien transmissions are often the result.

Note that the CL instruments are designed to thwart attempts at typical music, particularly in synchronization as relates to the PB. Gongues and rolls can make and respond to rhythms, but they will be offset from actual clock pulse timing. I find it interesting to attempt, but accept that the results will be a compromise.

The PB and CQ have a great synergy. I wouldn’t want PB without the CQ at this point. I’m currently building a stand which will hold them together. The CL instruments can be played alone but they shine when used with others (and Voltage Memory, Rollz5, Serge, tape recorders, mics). In this sense it doesn’t matter which one you get first, so long as it’s not the last.

It sounds fantastic - congratulations on the build, looks amazing.

thanks so much!! looking forward to getting to know it better in the coming weeks. i should have picked up some of the alligator clips for testing it more exhaustively - i had hardly played with it prior to getting it mounted in the box.

@qwoned good question! i’m honestly not sure of the details. i’m going to check in on the details, i’ll post them in the Chicago events thread.

I finished building a cocobutter stand today. The instruments are tied down with cord so as not to damage them with fasteners or adhesive.

Is it too much to ask for some photos of the guts? I’d love to see how you fit it all in there. The layout is really nice and the enclosure’s beautiful! Amazing work.

first of all, thanks! i’m really happy with the way it turned out.

the guts are… a mess. everything is pretty much just crammed in there. i was intending to build a box that was ~30% larger, but realized that building a box was out of my depth given the limited set of tools i have at home and my skill level. instead i opted for the biggest plain wooden box from michael’s craft store and adding stain/hardware myself.

all of the PCBs share one 9v battery power source and one TS audio output; they’re all daisy-chained together in a big circle according to where i planned to mount the corresponding jacks/pots. as i mentioned over in the other thread where i posted some in-progress photos the other week, all the daisy-chaining was probably the most challenging/frustrating part of the build.

if i was doing it again i’d probably figure out some kind of minimal mixing solution and do separate audio outs - some of the circuits can get quite a bit louder than others, and there’s really nothing i can do about it in the box’s current state. the fact that they’re all crammed together also creates a little bit of accidental “cross patching” where bare wires touch each other. for the most part this cross patching sounds pretty cool, and since this whole project is about embracing imperfection i’m fine with it. happy to answer any other more specific questions in the DMs!

Absolutely killer looking and sounding instrument. That second recording is just beautiful - really my kind of thing! Looking forward to hearing / seeing more.

A little sonic exploration with the Plumbutter 2 and Eventide H9 today in the studio. Something I thought that some of you might enjoy :smiley:
Thanks for listening!
