Only saw this picture now, looking great!!!!  Did youu get the push buttons working? As you encountered problems iirc our convo on the discord server. |

I did! I'd made the mistake of following a generic 'wiring a pushbutton' guide instead of trying to follow your schematic for that part, tested it on the breadboard to see if it would light an LED (it did!), and didn't factor in that the interface with Pico required a totally different signal approach A quick reconfiguration and they work splendidly! Still have to fix a little quirk with the CV outs and LEDs - i've got them all connected together (figured i could just use the same signals coming from the op-amps and send it to both LED and output headers) but it looks like that is messing up my output signals badly, its only coming though at like a quarter of the correct voltage, seems to be peaking about about 1.8v. I've confirmed that the full 0-5v range is coming from the op-amps so it's definitely the last stage by the LEDs that it goes wrong. TBH i almost didn't include LEDs at all so if it's a real problem i'll just drop them again. So close to complete! |

Considering the LEDs, did you connect them parallel to your output to output headers, or in series? In case you connected them in parallel, that should in fact work, unless the op-amp has to deliver too much current for LEDs (which would really suprise me). |

I did them in parallel (i think...) but everything was extremely cramped in that area and its entirely possible i bridged some connections accidentally. No matter, the LEDs aren't super important so i've disconnected them for now, I'm content with the module which otherwise is working just right  |
