    That weird LP+HP response (9:15) reminded me of allpass filters with lots of phase shift: The square wave doesn't sound different, but the individual components get delayed differing amounts: This can help "distribute" the spectral contents of "wide" sounds for better gain control, its used in studio mixing.
    Impulse response would've been very interesting to explore here! I bet the group delay will be obvious when you send only a singular square pulse in
    I'm going to build this thing soon, might edit results later.

    Awesome series!
    Pro Tip: 28:00 when soldering components with leads, trim them prior to soldering because they are heat sinks. 😉

    I cannot in so many words relate how much I appreciate the level to which you have gone to impart this information. I had previously known quite a bit and through watching your channel it's given me a new perspective on the way I build filters from this point forward. Using diodes the way you have seems counterintuitive. That said I won't even try to deny the results. Kudos man.

    “I am interested in getting a module” because at 9:10 you have found the All Pass Filter. It’s able to change the phase of the harmonics of the sound, but our ears cannot feel the difference.

  • @sanderbelmans6788
    @sanderbelmans6788 3 года назад +3

    "I am interested in getting a module" - Hey Moritz, as always great explanation. You are correct about the soldering problem with ground connections. This is why most PCB software default to 'thermal reliefs' on pad-to-plane connections. I am looking forward to more of your work!

    "I am very interested in winning one of these modules!"
    I stumbled across your channel while looking for a method of creating an oscillation unit with cross fade capabilities as I was struggling in my circuit design. I ended up walking away with a fundamentally different and much better understanding of electronics as a whole and couldn't be more thankful. By piecing together what you showed and using it to augment my own experience I've been able to get 2 modules off the ground in the past 2 weeks in my spare time, where as my first one took nearly 2 months and still has problems.
    Thank you for your work, truly!

  • @The_Digital_Arts_World
    @The_Digital_Arts_World 3 года назад +2

    Moritz,
    First … thank-you for the detailed video on the design and development of this diode ladder filter. Although i have had extensive training in electronics, so much of that basic knowledge has slipped away with age and continuous changes in what I did for a living even though I still do build my own stuff once in a great while. As you get older, the “I want it right now” starts to kick in more and more.
    Second … I am definitely interested in one of these modules whether it be in a give away, manufactured, or DIY form, so please keep us posted.
    And thanks for the incredibly well done video !!!

  • @droningbrightness3403

  • @moshly64
    @moshly64 2 года назад

    At 19:00 you talk about the diode on the output of the op amp, you can make his into an 'ideal/precision diode' by moving the negative feedback input to the other side of the diode. Then the op amp cancels out the voltage drop of the diode.

    I was able to learn enough to modify this during the build process to work with my volca modular.
    Thank you so much for these videos. I now have a double wavefolder and a sweet filter for my volca!

      @DroneDrummer Год назад

      @@MoritzKlein0 haha no but I can try to put one up! I only changed the 3 resistors at the beginning right after the first 1uf and then again at the output. The one used to amp it like crazy i had to drop down along with boost up the one after the last 1uf to slow down the drain and stop it from filtering at base level. Wish I could post a pic! It looks so awesome on the breadboard

    Great video, thanks. Try to look for "Thermals" setting in your PCB design tool. It connects ground pads to ground plain over smaller wires only, which makes soldering much easier. I learned this immediately after soldering my first PCB 😁

  • @thecasualengineer99
    @thecasualengineer99 Год назад

    28:00 Your solder issue where an earth plane is concerned (if you haven't already found out), can be partly addressed by a setting called thermal relief in the PCB design. Otherwise your soldering looks adequate and gives the results needed.

    brilliant design (!)--the lack of headers connecting the two boards is excellent, as well as providing holes beneath the 3.5mm jacks.

    DAmn, this is some quality content. I just recently started to get into eurorack by building a rack myself from scratch with the goal to keep everything as low budget and diy as possible. So far i have a very basic osc and dirty filter (WASP based). I of course would love to get one of your quite professional modules but if i don't win i will certainly make up my own board based on your design to implement it because damn does it sound sweet.
