    It turns into an audio down sampler, not a bit crusher. Bit crusher works in the amplitude domain number of available vertical bits (looking at a waveform on the screen). Downsampling is like the sample rate of a DAW or CD it's time based and that's what happens here. Over time you're telling it to pull samples (CD was 44.1kHz etc) and running at lower audio rates we hear the tone and affect of the lower sample rate ... you asked so I rambled.

    • @movax20h
      @movax20h 5 років тому +5

      It is not exactly down sampler. For the downsampling to work without aliasing, you need to have low pass filters on input and output, and they need have cutoff below the Nyquist limit. Otherwise, you get various aliasing artifices, which can be interesting sonically of course on its own. Actually if you put reasonably high sampling frequency, and appropriate low pass filters, you will reconstruct original input signal ;D

    Yeah, understanding sample and hold goes hand in hand with understand Analog to Digital Conversion. Because a computer has finite memory, it must encode waveforms into a series of finite steps to store, and it uses sample and hold to do it. The trigger clock denotes your sample rate, be it 44.1 kHz or up to 192 kHz. Its frequency resolution.
    Your S&H is running below 44.1 kHz and so you get sample crushing effects.

      I completely agree....the reason kids are not going modular is because 99.9% of the "jams" you hear are either 'plinky-plonk-plunky-plink' or dark ambient drone...because they place constraints on themselves. I am no musician but never thought purposely restraining yourself was an art-form. Me, I don't use a DAW, but I am also not completely modular either. I'm semi/modular+, meaning everything play is live, but the majority of sounds are presets I've created (or borrowed) that I'll assign to a workstation such as my Roland JD-Xi or Yamaha MODX...but I never know how all the sounds will perform together until I play (and that is what you get). Nonetheless, if you check it out I play Trap, Techno, Trance, Dub, House, Hip-Hop, DubStep, DnB, Electro, Funk, and any mixing I do is on my phone (iMovie). Ha ha So I might use my DeepMind12 for bass, my JD-XA for lead, DFAM for drums, etc. Send it all to my workstation, assign it to a section/key and get busy.
      Long-winded way of saying you can still go DAW-less, organically create your music, and get your sh*t to knock.

  • @Neurotypique
    @Neurotypique 6 років тому +44

    I think this is more of a sample rate reduction effect than a bit crusher, it's basically because you're reducing the sample rate, it's like you have your analog vector curve and the sample rate is the resolution of the pixelated image you get out of it. By lowering the sample rate of the sample & hold, your sound is getting more and more "pixelated".
    If someone could explain how a bit crusher works and what's the difference, that would be very interesting!

    • @dysbomb
      @dysbomb 6 років тому +29

      a bit crusher reduces the resolution of the amplitude of the wave. Like 8bit audio only has 256 values to play with. The change happens at any time when the audio passes the threshold between values. This is the difference S&H reduces at different time intervals and a Bit Crusher reduces at different voltage levels. So if you are looking at a waveform one reduces on the X Axis and the other on the Y. Now i'm gonna go bitcrush some S&H for full XY control

      @Neurotypique 6 років тому +3

      ​@@aeu05172 if we're talking about applying it to a pure waveform it will introduce amplitude steps, your sine wave is going to look like little steps going up and down. The more you bit crush, the less steps there are vertically ( a midi signal has values going from 0 to 127 for exemple ). The sample rate will affect the width of your steps horizontally, it's the time your value is held.
      If you're not modulating it, your steps will be even.

  • @timnordberg7204
    @timnordberg7204 6 років тому +1

    A variation on this patch I love involves chaining multiple S&Hs into a shift register before one of the voices. Using the master sequencer's output and clock as the sample input and trigger source, you get a canonic variation of the master sequence (shifted some steps behind, similar to a round) on the output of the shift register. Adding one more S&H in that chain, clocked instead by an individual gate sequence for the "canon" voice, results in new patterns that are based off the same data set as the master sequence, but keeps the voices from following exactly the same patterns.

    • @timnordberg7204
      @timnordberg7204 6 років тому +1

      YMMV getting the S&Hs to chain properly: successful implementation may depend on the charge and dispersion times of the capacitors in your analog S&Hs and some under-the-hood sampling times in your digital S&Hs. A quantizer on the back end may help combat droop from analog components. If it doesn't work quite right, there's always O_C.

    On the bit crusher thing, I think it's not really a bit crusher but sample rate reduction, which bit crusher typically also does. You're limiting the sample rate of the input signal to the frequency of the square wave. Is there such a thing as the opposite of a slew rate limiter? A slew rate aliaser? That would be similar to a bit crusher I guess.

    What is the module you’re using for the bass voice?

    Whoaaa, this reference near the beginning: "…that we would know from the Thick-Stark texture synths of the yester-'90s" was to me as gloriously opaque and tantalizing as Rutger Hauer's Tannhauser Gate speech. I kinda want to know what you are talking about… but… I also kinda don't… okay no, yes, I do

    Another great video! What module was used to record and process the vocal live? That was cool

    Alex. You say your A148 was faulty. What was the fault? I’m on my 2nd one after returning the first after the 2nd output started giving a dirty signal. Now the second module is doing same......aaaargh the pain!!
