Love using Rolzer to sequence the organs glitch inputs, for ex if using Sidrax with PlumButter I might patch a Sidrax Red to modulate Gong FM purple, then the Gong Orange cv back to the Sid Oscillators Blue FM, Then explore patching from Rolzer to the Sid green glitch inputs. Now since modulating the Gong’s blue verso/inverso effects its Orange and Grey CV out I might patch another Sid Red to the Gong verso/inverso blues and then more Rolzer back into its glitch inputs. Then maybe patch the Gong(s) Grey to main Sid Grey pitch and/or Chaos inputs. Loved doing this when I only had PB and Sid but there are only the 2 pairs of Rollz on PB, Rollzer opens up the possibilities plus gives us those wild 5 rollz to play with.

Rolzer patched to the DDD Schmance are also something I enjoy exploring, or to modulate Cocoquantus many inputs. It’s a great way to synch multiple CL instruments together.

Update on my personal Super rollz-5

this post is worth $1147.55

haha, rolzer is awesome. with that sorta patch if you run the Sidrax Main Stereo out into Gong aux in, then to start anyways, only monitor from the Gong White Audio outputs into Cocoquantus Green inputs. Now when you play the barres you have the Sidrax being filtered by while also modulating the Gong filters. Then can patch Rolzer to Coco flip/skip, along with those quantussy green quantussy circel nodes to have some synch influence over its modulations to send out.

Stuber is really Amazing though, lot of very coool stuff going on.

So while working on that DOGVOICE board, I got an idea…

This is DOGSCRATCH -
4 Preamps x 4 Anti-Preamps (Trigger Delay = “x” Resistor Value - & Hairy Cap? - Different values on each “key”
Large “pads” are Preamps (+)
Small “keys” are Anti-Preamps (-)
Corresponding Banana Jack Outs above each “Key”
“Keys” are isolated to prevent triggering juxtaposed preamps/antipreamps.
“Keys” will have rubber grommets/orings on each standoff - vibrations*
“Pads” are scratch surfaces - much like the MTM Mikrophonie or Analog Output Mikrokosmos (KOSMO Format)

Exposed unconnected trace circles where the 35mm Piezo (Large key) and 18mm Piezo (Small key) may be soldered to the rear of the “key”.

Battery Clip or 12v DC Barrel Jack.

Future idea is a reversed version with shallow standoffs and a taller bottom panel for Eurorack mounting - subjective to how the triggers work - as I have never even built a preamp lol.

Let me know what you all think!

(I sent this idea off to Peter B. tonight via email )

[disc0p]

Looks amazing! Holy moly.

hell yeah in 20 characters

That’s an interesting idea, I’m looking into something quite similar as I’m planning to add two drumslits on the sides of my Dogslit.
I think i’m gonna lasercut some light (2mm) acrylic pieces and glue piezo underneath. Piezos are extremely sensitive to flex, and with Dogvoice you can have amazing control over pitch with really small variations of pressure/flex over the ‘barres’ (think Sidrazzi/Tetrazzi).
My only concern would be about the flexibility of PCB material, maybe you could make the plates with thinner pcb than usual ?
Also just some random thoughts :
• You can replace x resitor with a pot, gives you a lot more control
• I think (need to investigate more) that hairy caps influence pulse width, and more pressure influence its amplitude.

[n-So]

pardon my ignorance on this, but is controlling Plumbutter 2 with eurorack CV as easy as using one of those converter box things (ex lo-gain), and connecting the plumbutter ground to the box ground?

[SPIKE]

correct!

i have three of those little boxes for just those purposes!

[crucFX]

Logan will also make an Attenuator Version if you message him on FB

[Jonny]

Yes but be careful with those brown jacks on the rollz

[reallyok]

i’m new to peter’s stuff… can you elaborate why?

[Jonny]

I’ve read something about plumbutter messing up somebody’s maths module. These jacks put out a strange negative voltage and the circuitry is not a standard cv voltage. Peter himself recommended not plugging those into other systems, but didn’t really elaborate why. I had asked him a question about coco, which he said was fine and mentioned the rollz jacks in passing. Maybe someone else here knows the exact reason?

[crucFX]

This is how I explained it for my 2-Roll LFO x8

"The Brown Jacks tend to hang around -2v on their pulses, and could potentially damage gear that is not meant to receive Negative Voltages.
These Brown Jacks are commonly referred to as “androgynous nodes” and are meant to be patched into one another to affect the outcome of the randomly generated pulses from each “Roll”

The Red Jacks send out Positive Pulses that tend to range from .5v to 6.5v and can be used to feed into the CV Input or Trigger of other gear."

It is a general disclaimer as the sandrodes send out negative spikes that could potentially damage gear that is not meant to receive these type of fluctuation negative spikes.

I highly suggest reading up on the Plumbutter page as he gives general guidelines for the various jacks and their color associations.

[reallyok]

thanks for the detail! i had been reading up, i guess my confusion stems from the meng qi banana/euro conversion module, which itself has switches to block those negative spikes, as far as i understand it.

i guess i wasn’t sure if such voltage blocking was standard in other banana/euro converters, or if this referred to something else.

[cowboyelectronics]

im finishing up some conrad papers, dogvoice, and namastitar (non-meng qi) builds and was wondering if anyone had any info to share on what pots they used. i think i’m just going to begin with 10k for all of them and then take it from there.

[crucFX]

I would imagine 10k just like on rollz.
That was what I planned on using for mine

[cowboyelectronics]

thank you for the reply.
in other news i added ground jacks to my five star brain, rollz 5, and esoterica spikering w/ rollz 3+4. five star brain and rollz-5 work great together but i fried my spikering somehow. whoops

[jlmitch5]

big update to the gerassic organ project…I have pitch cv working! right now I can dial in 1/2 v/oct response…I think I must have some resistors wrong somewhere in the voltage dividers that flow to the VCA chip’s voltage control input. audio here is just the raw output from the gerassic organ breadboard.

whipped up a super quick little crow script to sequence. as you can hear it basically acts as an offset for all the notes. you can get more normal sequencing if you just have triggers going to one button.

function init()
    input[1]{ mode      = 'change'
            , direction = 'rising'
            }
end

note = 0
notes = {12,12,12,12,12,12,12,12,8,8,8,8,15,15,15,15}

input[1].change = function()
    note = note + 1
    output[1].volts = notes[note] / 12 * 2
    note = note % #notes
end

EDIT: imgur added some gross compression. here’s what the actual raw output sounds like:
