AO Dual Quantizer

If you wanted a black panel, about 5 of these are going on Reverb or Tinder tomorrow-ish. I’ll post in the BST thread then.

Those panels are looking sharp in black! I’ll have to keep an eye out for your post

Christian Bloch,

I very feel this aesthetic. I’ll get a black panel and a red board from you when you post it.

@analogoutput working on this now. Is this accurate or is the board accurate? I’m noticing some discrepancies in the 10k and 1k resistors and want to double check before soldering?

I don’t know what “this” is. What discrepancies?

I’m putting the Dual quantizer PCB together and resistors R27 and R30 (and maybe a few others) are labeled on the PCB as 10k. In the BOM they are 1k.

I double checked and it’s just those two, R27 and R30, so far. I’m guessing they are 10k based on the schematic.

Doh! Yes they are, and I’ll put further comment on the Litany topic. :grimacing:

I pushed an up to date BOM to the repo.

No worries. Thanks for checking. More corrections for the BOM:

  • R24, R23, R21, and R22 should be 1k
  • R28, R25, R15, and R18 should be 100k
  • R26 and 29 should be 1M

I’ll note anything else as I go.

No need, I re-generated it from the current schematics. Ignore the BOM you have, download the new one if you like. It should be entirely correct.

It’s perfect. Time to see if I can build this without having to post to Litany. :slight_smile:

I ordered PCBs, now I’m filling my cart with the needed components…

I have a hard time finding these, nobody seems to stock them :

After seeing another video of the quantizer in action, I decided to finish it up. Before I do, I would appreciate another set of eyes on it (as I’m no expert).

Here are the two halves with the wires labeled:

And here are a few close-ups:

I am a little stuck and have a couple questions @analogoutput

What value of resistor do I put between the middle toggle leg and ground? 10k?

On the trigger 1 jack, do I need to put a 10k resistor between it and the VCC?

The build guide isn’t more than an overview, for the details there’s just the schematic.

For the toggles:

100k resistor.

For the trigger 1 jack:

Yes. (It says “Gate” in the build notes, meant “Trigger”. I’ll fix that. I’ll also put resistor values in.)

I’m frustratingly close, but I probably should call it night. I followed the instructions to build/upload the code and am running into an error. I double checked the folder names and contents. It’s all there. I’ll take another shot at this in the morning with fresh eyes. I’m not super new to Arduino and the fun library management, but this one surprised me. Again, thank you for all of your help.

Also here’s where I ended up:

To properly analyze the problem you need to show the code around lines 185 … 188 but lacking that in lines 185…187 each you are declaring a variable and giving it a value (false). This is apparently not allowed in C++ at that location in the code.

You could try the following: declare the variables without giving them a value and then, on a separate line, give them a value. That will probably work.

so instead of

static bool a = false;

use:

static bool a;
a = false;

Logically speaking one would expect the same error, but in my experience C++ compilers sometimes come up with confusing error messages, so your mileage may vary. B.t.w. keep in mind that the error might also be caused by the code preceding this particular variable declaration.
