Percussive Noise Voice, Hihats and Snares - DIY Modular in a Week 9.4 

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!

"You want a module. You want a modular. And you get the knowledge." Epic :)

Oh boy I want a crispy sound like that !!!!

this sounds simply awesome. that crunchy, crackling, crispy snare + a sharp hihat. can't wait to build something like this! thanks

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!

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.

Thanks for the shout out! Looking forward to see what you can do to improve the snare noise source, thanks for all your experimentation.

When the challenges become fascinating and almost more fun than success ... SDIY at it's best. Thank you.

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.

Just found this channel. Amazing work man. I'll be ordering some parts and building along with some of your older videos.

Great! Have been waiting for a new episode. 👌

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? : )

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! 😎

You must match the HFE of the transistors to get your desired spectrum

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 if you like the sound of crickets , sounds like these transistor noise drums soundmaster sr

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.

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.

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!

Awesome

Has anyone got a strpiboard layout for this? I keep really dramatically sucking at this one.

Hello, did you have the dead link please ? I wanna try to look at it with the wayback machine

Hi, do you think it’s possibile to add a pitch control? If yes, which component must be changed? Thanks!

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!

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 :)

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!

hello kristian, i have few question about some modules, can I contact you per email or somewhere? thank you in advance
