I am hoping I am not going to need this, but experience tells me I will.

Hey @synthetech great project! I tried bulding one with the UDA1334A DAC Module and seems nothing is coming out. Might I have the same problem as the PCM 5102 as faulty soldering from the Mfr? Everything else sounds good according to my vmeter.

I don't think there are any solder jumpers on that board. It is possible the board itself is defective. Did you check for signals with a oscilloscope?

@@Synthetech Yes, everything seems ok. I will replace de module just to be sure. Do you think It would be better to go with the PCM5102 dac and the St-link powering? Tank you for the reply!

Sorry your having issues. I tend to like the UDA DAC because it looks better built and I was able to buy several for 2.50 USD ea. Power should not matter but I usually have a stlink connected because I tweak the code.

I just did it all and check with dso 138 oscilloscope everything is OK but I don't hear any sound from out of PCM 5102 DAC I connected with little stereo jack in to my PC or any other amplifier with speakers but no sound :(... what can be problem if I dont hear sound but all other testing 6N137, Blackpill, PCM board works on oscilloscope?

Hi Dubravko. It may be easier to just email me so you can send pictures of how you have this connected up. I'll post my email here temporarily and then I'll delete it by tomorrow if I don't hear back from you soon as I'd rather not leave it posted up for long.. it's****** Give me a shout there and maybe a few pics of what you have set up and I'll see if I can help. Usually I'm very busy with work, but it's holiday now for the next few days for me (I'd rather be making synths than what I do at work!) - Blaine

@@jmatonis Hi Jason. Could you send me a picture of the back side of the DAC Module? There are probably some solder bridges not completed by the mfr that youll need to complete.

If the jumpers on the back of the board aren't jumpered, jump H3L between the H and the 3 and it should start working. This was an aliexpress board. I believe this is a mute function. Happy building! :)

Is there a way to use potentiometers on the breadboard instead of the gui? People love knobs and if they had a way to adjust all those parameters in real time without needing a complex controller that could really get some people interested. Anyways I will be trying this over the next couple of weeks so expect plenty of questions lol

There could be a way, but that complicates the build and increases costs.

In Floyd Steinberg's build, he's using MIDI knobs to control parameters, at 7:13: kzread.info/dash/bejne/eJ6AxbKHmN2np9I.html Surely that's the way to go!?

@@tkonan Not sure if that's falling into the "complex controller" catagory. But yes, having a hardware midi controller is quite easy to use with the BP Synth.

@@tkonan I suppose but you need a midi controller for that, would be cool if this build could have the knobs / sliders on the breadboard itself
