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 ...

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...

Here is why there are no summing cables, OP: https://www.prosoundweb.com/rane-note-why-not-wye-or-y-for-that-matter/ tl;dr: "A wye connector used to split a signal into two lines is being used properly; a wye connector used to mix two signals into one is being abused and may even damage the equipmen...

Big fan of Antumbra!

Cool modules, terrible documentation and zero support

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?

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.

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?

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...

Double post, I don't know how to delete this one

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...

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

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...

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.

Do it! I'm bummed I missed out on the original.

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?

I just saw this while looking for knobs, as one does on a Friday evening.

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.

Well, I replaced BOTH of the v2164s and the problem is still there. Wtf

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...

Just ordered my PCB and panel.... lots of questions, starting with...

Did I order the correct display?

display

yes

Well how about that
