Love what you're saying here. When I started building (in lockdown) I could solder but I knew nothing about electronics. I couldn't follow a schematic and had to search for vero layouts. Two+ years later I've modified many schematics to build exactly what I want, and also designed a few simpler modules from scratch. My modular just gets bigger and bigger as I find 'just one more' thing I need to have. I still don't know as much as I'd like but there's a huge sense of acheivement in producing music from circuits I have built myself - something I would never have believed. Long live DIY!

Yeah exactly! 😃 I would guess that “one more module” goes hand in hand with “just one more knowledge” to make that one more module. 😬 it really is a journey and a transformation. Thanks for the insightful comment. :)

"You want a module. You want a modular. And you get the knowledge." Epic :)
ELECTRONICS is probably the most ‘Eureka moment’-filled skill set. While learning electronics, it seems that the knowledge is generally acquired ‘by mistake’ a lot of the time. Concepts can be read and studied and never need to be fully understood. By building these circuits, the concepts can easily be demonstrated and so we need no knowledge to demonstrate the principles. It’s a sort of skill set where I need to not worry so much about what I don’t understand, and just worry instead about getting the parts of the circuits correctly oriented. Then when I have these ‘Eureka moments’ later, I’ll remember that this is just how many of the lessons in electronics are finally understood. A truly rewarding skill set! Rewarding, even beyond the synthesizer modules that you build throughout this learning process!! THANKS for sharing!

Exactly so... I also struggle with understanding the theory. But putting it to practice often shows it oh so much clearer. 😅
Great hi-hat and your idea to use the LDR is genius to get open and closed sounds! The “crispy noise” does sound like the static sounds of a vinyl album playing between tracks.
Great episode! The snare has a nice clap-like quality to it, it's missing a hard transient to sound really snare-y in my opinion. White noise source makes a big difference, I've mostly synthesized drums in software where there's much less variables but being able to swap the noise source out can make for cool experimentation. Maybe when I get to these I'll add a switched jack on the faceplate for patching one in.
Got confused with your schemas having "0.005uF (50n)", but trusted in original and put 4n7. Also put just 2n3905 as transistors. Sound good, noise gen bit grainy, but gives "person" for it. Good module with only few components. Made another for sound scultrure and sounding even better, good luck in silicon lotto? Btw. used same noise gen for both, doesn't seem to care.
A little consideration: A snare is a blend between a tom/bass drum (the leather on a real drum) and a noise (which in real life mimics the springs on the bottom of the frame holding the leather). Here we only have the noise part. Mixing it with an oscillator and a Twin-T filter would give a better approximation. Time for version 2 of this module? : )

Yeah. I did a previous module called the BaSnaHi which used the concept you suggest. This one is mostly good for hihats as you also point out. But yeah a full on drum module that could make a whole range of sounds would be nice. :) I’ll get on it…. Sometime. 😅
@ Can't wait for a Delptronics LDB-2e clone! 8 voices, independently triggered, with a mixed output. In as little as 6HP! And the price is quite interesting as well (175€, if you manage to find a dealer) Not only hard to find (you have to order it in the US), but there are also huge import taxes (not even to mention shipping costs). And it is "temporarily" SOLD OUT.
That's beautiful! What's a simple way to add an amplifier on the output? (By the way, I love this series! Thank you a lot for having shared all of this)
Hi Kristian, Nice job! I made the snare circuit (with a few adjustments for taste), and I have a question: the more decay I add, the weaker the initial snap of the snare is, and I wondering if you know of a way to maintain that snap whilst also increasing the decay?
I wonder if you could replace the noise part with the noise circuit you built some while ago. I seem to remember you saying many of the noise circuits you tried did not work, so I guess they are just funny like that. I built the "R Anderson" circuit which does look similar to the noise part of this and does work. I think I must have built it because you said it works. I can't remember that part! 😎

Yes you can plug in other noise source. I did that in the beginning when trying it out. As you say this looks very much like the noise source I did for the white noise module so it is a good working design. It’s just something with one of them that seem strange. Then there is the noise source from the colored noise module which used a zener diode I think.
I think that weird noise snare sounds kinda cool, not like for a snare, but I think it could definetly be used as a perc thing. Thanks a bunch for showing the difrent parts of this circut, just what I needed. I was hoping to learn how some of that stuff worked by building a Rakit Metal, but it is a bit to complicated for me to reverse engineer. When are you going to release some music, or where can I find it?
Great sounding hats, I managed to get a pretty decent snare too after playing with some different caps. Can't get them to trigger from a clock divider though, needs a stronger signal maybe? An LFO triggers them ok.
4 года назад
I guess there is a threshold when the drum triggers or not. What value caps did you use for your snare? Maybe you could change the output voltage of the clock divider? Which one did you make?
@ I made the clock divider from your video, 8.1 I think. Not sure how to boost the output voltage from it but I have got the hats and snare to trigger by adding a TL072 buffer to the inputs!
@ Also, I want to ask you about the Moog high pass filter. I got the circuit working but the output is very low compared to the Rene Schmitz low pass filter. Did you have the same result?
4 года назад
Mathew Thomas great idea with the buffer on the input. As for the Moog filter I just tried, and I have the same thing that it is much lower in volume. I haven’t thought about it before as I attenuate everything in the mixer usually. You might be able to buffer or amplify the signal somehow? Or just use the mixer. ;)
I remember years ago I built some oscillators with transistors and their was always cross talk. So I may be wrong but would this be better if I ran the inputs and outputs thru an opamp? Thanks
This is quite off topic, but something seems a jit fishy with the logic module. It seems like some extra gates are slipping through depending on what is connected. Looking at the top output of the logic module from around 12:50, it seems to change behavior when you change some connection at 13:05. Listening on the Xor-Bell from around 13:35, I think it gets more triggers than it should. If I see correctly, it is fed with the XOR of /128, /32, and /16, and by my calculations it should get fewer triggers.
My suspicion is that it is when two signals change at once, which should not change the output, that something is not quite synchronized correctly, and if the signals dont change at once then the output might jump momentarily. perhaps something happens with the clock divider output when feeding multiple things at once?
Hi Kristian, I've been working on building this circuit but its driving me crazy. Ive built it twice and I can only hear a faint click of the gate in the audio output, with no noise. I've checked the wiring a million times so I'm a bit at a loss. I followed the original A_Magic_Pulsewave circuit since I didnt want to add a vactrol. Do you think it could be the quality of the transistors Im using (Im using 2N3904s from China)? Im confused as to how the noise is supposed to reach the output with that diode in the way. I'm also wondering specifically which part of the circuit you probed to check the noise circuit in your video. Any input is appreciated and thanks so much for you videos. They really have made social distancing much more tolerable!
Hi, do you think it’s possibile to add a pitch control? If yes, which component must be changed? Thanks!
3 года назад
Pitch on noise is probably done best with a filter. By using a bandpass you could “tune” it to a certain range. Or do the Xorbell circuit. It uses “digital” noise created with 6 square oscillators. That one is more tuneable. Or skip the xor circuit and just mix the six oscillators at different frequencies. Should also work according to some. (I haven’t tried it).
Hey Kristian! So, did you ever manage to figure out more about the weird noise result? I actually kinda like the "crispy" sound, like you said, almost a vinyl scratch source. I'm wondering if there's a way to recreate? In any case, I'll breadboard first and see what I get. Thanks as always, hoping to get back in the groove with these drum modules! Take care!

I think it is a matter of what cap values used. Try the values I used you should be able to reproduce it....
So, I got this working really nicely. Very cool! I wanted to let you know a couple things I found - 1) Using "plastic" caps worked much better than ceramic, and 2) I ended up using the original design without resister R5 and using 0.1uf for cap C4. This allowed the vactrol/cv to work. Otherwise, for some reason, I couldn't get the vactrol to work. Thanks as always!
Hi! did you find out what was making the first circuit sound like that? just some wrong value capacitors ? i actually want to try reproduce that crispy noise :)
3 года назад
It was just my choice of capacitor. So nothing wrong as such. Just try a few caps until you find the crunch you are looking for. ;)
Hi, i just built this, but i've got a problem: It generates a really high tone - nothing similar to a snare, hihat or other noises. Do you have any ideas, what i could have done wrong? Thanks!
4 года назад
Do you have a video or sound snippet so I can hear it? Maybe some value is wrong or you shorted something so it turned into an oscillator instead. ;)
@ I made a small video, in which you can see/hear it: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QFyYsSB2Gls.html All the values seem to be correct and i can't find any shorts either. Maybe i did something wrong when converting from schematic to breadboard layout...
hello kristian, i have few question about some modules, can I contact you per email or somewhere? thank you in advance

I would prefer to answer the questions in the comments of each video as others might find use for both the question and the answer. :)

ORGASTRON yep that should work. Just replace the noise circuit in this one to get different sounds. Build this circuit on breadboard without the noise circuit and plug in your colored noise with cables just to see how the sound will be. There might be some caps that need to be replaced as those “filter” the sound and change the character quite a bit. You might even remove them completely?
