Yusynth VCO - The Companion Text


I made a guide of important tips to accompany The Yusnth VCO guide. If you are building this analog synthesizer module, and need help trouble shooting or just want to know more... You can download the PDF from Google drive.


Good Luck!

    1. I read the Companion Text you created.
      Here are a few thoughts:

      PULSE OUT will have a higher output resistance than the other outputs. I didn't notice this when looking at the YuSynth website, but in reading your Companion Text it became readily apparent. I guess that is more of a comment directed towards Mr. YuSynth.

      How closely does the SINE OUT resemble a sine wave? i.e. what is the harmonic content of the waveform?

      I'm surprised that YuSynth regulated a ±15 V supply with ±15 V regulators. That seems unreasonable (as you have seen through testing different devices from different manufacturers) because the performance of these regulators is not necessarily well defined under those operating conditions.

      All in all, that was a nice Companion Text.
      In reading it, I found a lot of similarities between the YuSynth VCO and my own homebrew VCO (one notable difference being that mine doesn't include a linear Frequency modulation input).

      Thanks for taking the time to write that!

    2. Thanks for writing all of this stuff down.

      The YuSynth VCO is the first module I'm building and it's been a blast reading through your blog.

      Cheers and good luck on your project though I'd recommend going for 3.5mm audio jacks with labels after all because they're a lot more fun to patch than that breadboard type connector and they're directly compatible with any CV source or module out there (not to mention how neat and useful the direct visual feedback is).

      1. Thanks for your support! I have a lot of my Synth built now and the pin jacks work great and save a lot of room on the front panels. Let me know if you need any help with the VCO. :)
