I'm a circuit bender. I started in 2009, and yes, I do use LEDs, but in the form of vactrols for modulation. These days, I'm building a full desk for electronic music and plan to make more of these devices. The idea is to produce an album 😎

ironically the only module we can think of that's a liscenced product... does use vactrols. and i don't blame them, it's the easiest and least invasive option

this sounds a lot like the process for converting a guitar pedal design for modular, for those who'd rather not involve vactrols. you end up with a maze of analog switches and delicately balanced JFETs

Yeah and going back owe it I think this is really the best LPG model — at least in VCV land. Sounds vactrol-y!
Glad I own the Doepfer module too though as those vactrols are getting hard to come by. I would gladly trade all earthly possessions for LPGs.

It was great to see you as well!! Curious speaker setup! 🤷♀️
I think TipTop Audio was the first company to clarify the vactrol ban in the EU/UK. Make Noise have the DXG & now the QXGs. TipTop Buchla 292t has vactrols & I think offer one without for EU sales. Not sure how strict the ban is on Eurorack.

Did you slightly melt the end of that LED? Did you know that nowadays Vactrols are banned in the UK (maybe the EU as well) due to Cadmium content? 🫤

oooooh! Love me some Vactrols! I've put together my own after purchasing a 0hp Vactrol LPG kit that didn't ship with a number of key components. Mine were not as fancy lookin' as these.

the day I learned I could roll my own vactrols as a teenager was so huge to me
those things are expensive and you usually need a bunch of them!

Ever wonder what two oscillators would sound like if they modulated each other through vactrols? Probably not, but I did. So I built this module to find out!

A real Josh move. You know, in the old testament it's Yeshua which means Joshua. No idea where Jesus came from except someone somewhere decided to change it. In the synth bible we need to make sure Moog stays correct. Josh cannot be on the synth bible committee except for the section on vactrols

oh yeah i love vactrols! they’re so silly but so clever 🙂↕️

It's bloody magic. Its insane. Everything is either [too basic to make sense] or [such a complete reversal and abuse of what this component is for that it makes no sense]. Have you heard about vactrols yet.

oof, that's a bummer! such a fun little box
vactrols are super easy to futz with though so it should be DIY-solvable

Oh wait vactrols are opto-isolators, phew! My first concern was that they were vacuum tubes!

Poor Error Instruments Sputnik #synth is seemingly toast.
Might be in warranty so i should hold off on troubleshooting it on my own. Not familiar with vactrols.

Ik had al een tijdje een Aion-printplaatje liggen van een remake van de Dinosaural OTC-201 Opticompressor, liggen en dacht, laat ik die eens maken. Geen idee eigenlijk hoe ik aan dat pcb-tje kwam. De vactrols waren lastig aan te komen, maar het was de moeite waard, hij klinkt erg goed!

would also add a midi A-B switch on the TRS midi, a thing that litterally every mfg should be doing. come on folks it's a single dpdt.
voltage control over the analog filter is probably possible since the digital part is already modulating it and i don't see any malarkey like digipots or vactrols.
