Re: DIY Mutable Unsuccessful Builds

Just built an ST Modular Pyxis (Plaits clone) and I'm having this bizarre issue: it doesn't make sound on its own, but if I put a CV (not a gate or trigger) into the Model input, in this case I used an lfo, it acts almost like a trigger and triggers the sound, although seemingly not at the speed of ...

Re: Recommended high quality eurorack DIY brands

Had lots of success with PM Foundations so far. I've messaged the owner a few times and he's always been very helpful. What do you think of the quality of the front panels? I've never used the pcb material for front panels yet and am curious if they feel as sturdy as metal ones. Honestly don’t noti...

Re: DIY Mutable Unsuccessful Builds

Maybe if the diodes are facing the wrong way, but then you'd probably run into issues with things smoking.

Is the power cable backwards? Is the keyed header on elements installed backwards?

Re: MI Ripples - no cutoff freq control

On Ripples, IC5 (TL074) takes care of the cutoff frequency and CV controls. Check its orientation, as well as the orientation of the two diodes in that circuit (D5 and D6). If everything else works, the problem has something to do with that chip.

Re: Case Wiring, two Meanwell RT-65B

Question about dummy loads: I have the 85b and that whistles like you wouldn't believe. I want to put a dummy load on the 5v, but it goes up to 8A, does that mean I need a 40W or higher resistor? Those things are immense. And really, just from 5v to the resistor to ground?

ST Modular Cyllene v/o calibration issue

I was having issues with v/o calibration with two matched pairs of transistors and a tempco, so I switched to the THAT340p chip and a tempco, but it seems like I'm still having the same issues. I can get it to track somewhat well in the higher registers, but anything below @ C4 starts to go out of t...

Re: DIY Mutable Unsuccessful Builds

Hi, I'm having some trouble with a Rings build - I get some kind of crackly digital noise output, and none of the LEDs will turn on (don't seem to be getting any voltage output on the STM32 pins that are connected to the LEDs). I'm a bit stuck as to what to even check...all voltages are correct, no...

Re: uO_c 8hp ornament and crime.

I don't think I've ever seen a Teensy soldered UNDER sockets before. Did you solder the extra pin? Er... socket? I think this is one of the ones I built recently that has an extra pin that needs to be connected from the Teensy, beyond the two rows of headers.

edit: nvm, it doesn't have one

Re: Neutron Sound QVCA doesn't completely cut off signal

It was Peaks! I didn't realize there is a calibration procedure for Peaks, but then found a post from Emelie saying she left it out of the manual because people kept f'ing it up. Now the VCA is quiet as a mouse! Anyone looking for the Peaks calibration procedure: To enter calibration mode, power the...

Slew on O_c with stock firmware?

Do any of the stock firmware apps have a way to add slew/glide/portamento to a CV? I know there's a way via Hemispheres, but every time I switch over to Hemispheres I end up missing the stock apps and switch back.

Microbe Modular Meta Sequencer Bubble Display

I found a PCB for this in my backlog and was checking into it; are the bubble chips used for the displays possible to buy anymore? I know they haven't been made for a while, does anyone know where I could find two or should I just pitch the PCB?

This can be powered with the cable in either direction, something with the input diode sorts it out

It might be the 2.5v shunt, I'm not getting any voltage out of it.

When there's 0V going into the CV input, some signal still comes through.

I'm only able to get the sound completely attenuated by using exponential mode, in linear mode everything gets quiet but there is still a signal coming through. That's not normal, right? https://github.com/jakplugg/Neutron_Sound_build_docs/blob/master/DipTrace%20Schematic%20-%20qvca.pdf I think mayb...
