I think it’s incredibly cute that as soon as people decide it’s a good piece of hardware the anti capitalist people shut the fuck up. This needs to happen more.
it was good hardware when someone else invented it decades ago, not sure what your point is

Re: +/- 12V out of 24V DC power supply?

To be fair, this would only take 3 cheap voltage regulator chips (7805, 7812, 7912), snip How do you get the 0v? How do you relate it to GND? What do you feed the 7912 with? How do you preserve safety and effectiveness when patching into other gear? To be fair, you are vastly over-simplifying the p...

Re: +/- 12V out of 24V DC power supply?

To be fair, this would only take 3 cheap voltage regulator chips (7805, 7812, 7912), some filter caps, and a heatsink, but DIYing power supplies without any foreknowledge is not a great idea if you're going to use it to drive thousands of dollars worth of modules, particularly if the synth is going ...

Re: New Dreadbox Chromatic Modules just showed up on MG

I’m wondering if the ataxia modulator pumps out +10v or does it just do like 5? [edit: correction] in LFO mode it's bipolar 4.5V (9v P-P) on my cheap scope, and in ADSR/Mod it's about 0-4.5V. I bought it when I was buying some cables because it seemed useful, and it is, but it seems that the ADSR m...

There's also an unofficial firmware for the volca sample that clears it up without the need for external hardware, though it's kind of a bear to figure out at first

Re: i/o protection and impedances

You're missing the point. Dieter created his synth and modules in an era and for people who were setup machinists, not machine operators. That all changed *much* later. That's why I included Cwejman in my post. Different era and situation. His choice was and is demonstrably faulty. Not true for Doe...

Re: i/o protection and impedances

I get that, but developing a commercial electronic standard without keyed headers and strict cable format in the first place was still a mistake. I've been poking around in desktop computers forever and I'm pretty sure everything in there only connects one way, whether it's a Molex connector in a 28...

Re: i/o protection and impedances

If you have the opportunity to design a connector that can only be inserted one way or else to design one that can be reversed by the user --for no good reason-- in a way that destroys the thing you're designing, choosing the latter is a bad design choice regardless of the experience level of your u...

the key to deadbugging (in my very limited experience) seems to be wrapping leads around each other and exploiting points of common potential that aren't necessarily geometrically coincident. it's still a pain in the ass though, especially if the first thing you do in the build is glue down the wron...

Re: Oh dear...

I started on passive mixers, mults, etc a couple weeks ago, but eventually you run out of things to do in that realm. Now I'm a few hundred down the drain on components, blank panels, oscilloscope, etc, but it's really cool when you get comfortable enough with opamps to do "real" stuff. I haven't bo...

Re: The Utility Modules for Semi-Modular Synths Discussion

Here's a related question: does anyone make a Mother32-sized utilities-only semimodular? I'm picturing the same general form factor as a Mother or Neutron, with a patchbay on the right hand side and knobs on the left, but all dedicated to CV utilities such as attenuverting/amplifying/offsetting, act...

Re: Behringer MiniMoog Clone

Speaking of voltage, has anyone else thrown a multimeter across the LFO outs? I'm breadboarding a buffered mult and using the LFO to test it, and while the manual says it should be +/-2V, I'm only getting -1.7V->1.6V out of it. It's the same at the output of the D and the output of my circuit, so th...

Re: My under 2000€ 6Ux96hp project, I ask for advice

For what it's worth, I've been running a Mother32, Neutron, and Behringer D in an old 9Ux90HP Monorocket case off a laptop power supply for a while, and I just got a Meanwell RT65B today that I've been running for several hours. It has more than enough juice for the Neutron and seems to run fairly q...

Re: Neutron The New Behringer Semi-Modular Synthesizer

The side-mounted expander is a great idea. I bought a powered case a while ago with a janky power supply, so I've been using it unpowered for a while. I just pulled the I/O PCBs out of the stock cases for my Neutron and M32 and let them float in the case, daisychained with a wall wart power supply f...

Re: Neutron The New Behringer Semi-Modular Synthesizer

Thanks again, it's really too bad that there are no schematics for the thing. Next time I rearrange the case I'll probably take a close look at the board, but given that the envelope does seem to work normally in every other circumstance, I'll quit worrying about it 'til I'm in the guts. I'm still l...

Re: Neutron The New Behringer Semi-Modular Synthesizer

Thanks for the info. I wasn't planning on making an indicator light or anything, just experimenting with bare components. The current limiting stuff makes sense, but what I'm curious about specifically is why the ENV2 envelope behavior itself changes in response to the presence of the bare diode, bu...

Re: Neutron The New Behringer Semi-Modular Synthesizer

Hey all, I've discovered a quirk (or busted my Neutron). I threw an LED across the ENV2 output and it acted like the sustain knob was set to full, and I see the same behavior now if I run it directly to the CV input of a DPLPG. If I run ENV2 through an attenuator first, it acts normally (and trigger...
