I just spent all semester in college learning about filters and amplifiers. It was horribly dull and at times made me want to change my major. But this video showcased such a cool application of these concepts. Seeing how music relates to electrical engineering has been one of the things that’s kept me engaged with EE. Thank you for a job well done.

This helped me understand how the 808 cowbell ended up sounded like it does. I know some people love that sound. I've always hated it. But now at least I understand where it came from.
If you're looking for video ideas... it only makes sense to put your drums and sequencer modules together into a drum machine! I'd also love to see topics like analog chorus/other fx and that "3-channel mixer part 2" idea.
@@MoritzKlein0yes i noticed what you are doing i liked the 808 cowbell live stream featuring Simon the magpie. And keep it up with your video's i like them a lot
@MoritzKlein0 please do keep making these. I'd also love to see a video on building all the drum sounds into a drum machine with an audio mixer built in. I've been slowly following along and building these modules, and absolutely love them!
I am ordering parts to build this today! I have a degree in EE and I know all about the high level operation of synthesizers but ive never seen a video that breaks down actually building it in modules like this. LOVE this video!!
As a retired electronics engineer, i found this a great video, i was thinking virtually the same as each cenario cropped up,which made me feel good. Back in the early 80's i designed a 90 pot, modular synthesizer, which used many op amps for wave shaping & voltage manipulation. Thank you.
Your step-by-step explanation is very interesting. I study and work with analog synthesis, analog synthesizers and I'm fascinated with Roland's engineering for modeling these complex sounds. Fantastic!
@MoritzKlein0 I'm restoring a Roland Mt- 20 (I think) guitar effects pedal board. It's from the 90s. Hard to believe that's vintage. I had to replace over 100 caps. Great engineering man. What kind of caps were you using. The brand I mean.
thank you. thank you. thank you! that is the most abstract circuit ive ever seen, as an electrical engineering student, whos primerly intrest lies on how electricity is turned into the music we hear, this is the most practical thing ive ever seen. thank you!
I've built it and it sounds freakin' amazing! 🤩 Love that HH so much! 909 can hide with its sample hat seriously! That analog hat is unbeatable and with that CVs I can instantly modulate it so it sounds so alive! I'll definietly make it from breadboard into a fully usable module! Thank you Moritz! 🙏
There needs to be a whole unit in university dedicated to these kind of subjects. They always teach you the boring theory or at best they made me filter noise out of a music clip using matalb in my digital signal processing subject. It is really important skill for an electrical engineer to be able to apply these concepts on a breadboard and desgine such circuit using problem solving and the basics of electronic engineering but unfortunately they dont. Thats why amazing people like you are important, well done
I'm the same. What kind of caps was he using. I need to buy a bunch of quality poly caps and such. I play with power circuits mostly. I'm writing an album now and I'm going to make some synth circuits for it.
@@MoritzKlein0 yeah. Expensive in Canada moreso than Europe. 100 plus another 60 for tad and customs. Could you reccomend me a pack to buy if you get a chance.

I posted a video the other day of me playing my new 7 string to a drum track. It's just a crappy improv. I'm going to live stream my practice so I can go back and pick out riffs when I reamp and play it again. I'm making a short instrumental album over the winter. I'm 45 and not getting younger so I want to write something while I can still shred haha.

I'm going to teach him the blink sketch hahahahha. I'm laughing at me, not him. I have more stuff than I need so I make kits based on people's interests. No strings attached. I'm printing a gimbal for my phone so I can record the next vid properly.
@@MoritzKlein0 as soon as I get the caps I'll join your patreon my friend. Is that your preferred method or would you rather PayPal donations.

I'd also donate more as I tend to not like monthly payment plans. I could also send you a piece of test gear that's better than what you have. Like a better digital multimeter than the one you use.
This is genuinely one of the coolest analog projects I've ever seen. Going from a bunch of square waves to something that genuinely sounds like a piece of metal being hit, while being able to control all aspects of the sound, is crazy to me! and best of all, its just a big combination of blocks you've used before! Analog synth design is so wild, dude! I hope to get into it someday when I have the time and resources.
This is incredibly well made in every way, including your tonal choices and diagram aesthetics. Thank you so much for taking the time to make such a clear and informative video about this
This videos are fantastic. Thanks for sharing so much. Even though I'm years behind on electrical engineering, it gives a great insight for all of us working in different areas of audio applied to music,
After I almost failed my IC circuits class back in college this feels like magic. Fortunately I now am a bit more mature and know this is expertise that comes with experience, experimentation, hard work and not having a fear of failure! Great video!
I commend you on your choice of hi-hat sounds to emulate. The 606HH is such a classic. It has a really unique sound. You nailed it. Really cool man…Im an (almost) 50 year old going back to school for computer engineering. Was a professional drummer and DJ for many years. I’ve owned and used many drum machines and electronic gear. Really cool to see people out there doing stuff like this.
My first impression: Great sounding hi-hat. Other impressions: c.15:30 excellent animation. It's no wonder I'm seeing your stats (views/likes) bump up in real time as i'm watching this excellent video!
Moritz, I just stumbled on your channel, and I'm amazed by the way you explane the circuit, by building in step by step and explane each steps workings. Especialy I'm impressed how you explane the filters. Way better than my teachers did manny years ago.
Just recently discovered your channel and wow - your videos are really interesting! As a retired electrical engineer and lifetime synthesizer fanatic, I have never been done much discrete component-level design (mostly use higher functioning chips, etc) and having the simple circuits explained again is a great refresher, and even better being able to hear the effect of every change! I have a request! Would love to hear your analysis of the 808 hand clap circuit, and maybe one of the more complex versions like the "Clap Trap" or other stomp-box type clap circuits. Thanks!
As always awesome explanation.. This is not only how to design music circuits but how to open your eyes to find solutions.. Thanks Moritz for this well made video.
good job! Coolest thing with the electronic "drum" sounds is that they don't have to sound like the actual physical instrument. From this perspective, drum machines gives us lots of liberty.
Sir, I’m so glad I found your channel!! What nice content, and this is my first video! I have a long and fun road to drive! Thank you very much, your channel is incredible
I love your channel. Just got my first components. Your content is very solid, and Im so grateful. Making a drummachine excites me the most at this point cause Ive never had one and I dont like programming drums as much. Ive been making music for years and I know it will be a lifetime journey. But Im gonna give a try to every module youve covered, Im only starting now but Im super excited.
Sehr sehr cool gemacht ! Ich bin gerade dabei meinen Selbstbaumodular um eine Drumsektion zu erweitern (keine Kits, alles auf Streifenplatine und selbstgmachte Alupanels) und DIESE Hihat wird die erste Komponente !!!❤ Grüße aus der Stadt mit dem Herkules
really great video. the dissonant square waves at the start actually turned into a cymbal sound at the end of the processing. surprising what just adding together a bunch of pulse waves can do! while trying to figure out how cymbals can be done, i also found out that using XOR gates helps make the sound more "metallic" when used with a lot of square waves with different frequencies XOR gates seem to act as a sort of ring modulator, in a way, while also adding *more* distortion and dissonant frequencies to the sound. might be worth exploring!
yeah, i was thinking about incorporating XOR gates, but ultimately decided to stick more closely to the TR-606's way of doing things. would be interesting to throw them into my design to see what happens!
I haven’t watched this one yet, but I’d just like to say your videos are awesome and are going to be an amazing resource for decades to come….. thank you!
Your videos are so entertaining, educational and well-put together! I am nearly done with my bachelors in Electronics and I am still learning so much from watching these!
This is better and more informative than all the courses about PCB Design I've seen (I just started out and want to learn about electronics engineering)
Amazing video, as always! I can't believe how much I've learned from your videos alone. I thought this could be useful information to share for anyone watching: for this inverter oscillator topology, I've read the frequency can be reduced to f = k/RC where k is a constant that varies according to chip model (in your case the 40106). I did a quick test to see if this formula holds for the values you've shown and I've found k = 1.2. You could technically pick various combinations of R and C and measure the output frequencies and figure out experimentally the constant for the specific chip you're using, if you ever decide to go for another hex inverter chip and circuit simulation isn't an available option (for whatever reason). Looking forward to your next video. Cheers!
At some point the hi-hat was sounding almost like a snare! I guess the same schematic can be reused for this purpose. Thank you for the exciting video!
I just finished building this 30 minutes ago. I've just tested it and checked that everything works and played with it together with a couple sequencers and a rd-6. I have a Kosmo-modular i built myself and that is the only modular synth i've ever had. So this is the first time i even try a dedicated hi-hat module. I have had Moritz kick-module in my setup for a while though. A lonely drum waiting for his friends though come around 😊. The first thing i noticed while trying it out is how versatile it becomes with the cv-ins. It started to groove like a whole samba-carneval very fast. You know? When a hi-hat with a bit of nuance become more groovy than a full kit. If you want to make something very specific and control the details in what happens, you can. And on the other side you can just let things happen by themselves and they will. I like it a lot actually. It's really cool and a great tool. It sounds great and can do a lot. I didn't build it from the kit btw. I made my own module in Kosmo format and made the circuit on Vero board from the schematic. Thank you very much Moritz! I love your work!
Hi @JimmyHagerstrom, I was just about to start testing the circuit on my breadboard, then redraw the entire schematic on a stripboard. Although I love this exercise, would it be possible to share your work? Perhaps on the LMNC Forum?
@@hugoeymard-duvernay3210 I´m sorry for the late answer Hugo. I saw that you had tried to contact me about this via e-mail but i didn´t see it until recently. I have mailed you the material i have on it, i hope you got it!
@@MoritzKlein0 I still love it, it´s great. I use it with Juanito Moores 808 Kick, Eddy Bergmans verolayout and a 909-snare from a channel named Meebilt that designs and share his eurorack module designs. I really like how those three interact together. I still haven´t figured out how to get my MK-Kick to work though. :-)
oh thats wild that your designs are available through Erica synths. I got started on Synth DIY with their Polivoks DIY modules about 10 years ago. I love the way you talk through the design. I'm waiting on a breadboard so I can try building some of these myself.
Great work! For fun and out of pure curiosity, try recording the sound of a pulsating garden sprinkler on a calm day. By turning it into a sample, adding it as a layer underneath, and modulating it, you can also achieve an interesting effect with natural ambience . btw.170 thousand views and 9 thousand likes. You people really have no shame ;-)
You lost me after 7 minutes but This has been 40 years in the making. Thanks for walking us thru, whatever this is Really, makes me really appreciate what ever is going on here!
❤As an owner of an Arturia DrumBrute Impact it is facinating to see a lot (understand a little😅) of what is happening to make the sounds. You could use something like an Arturia DrumBrute (if you can borrow one) as a sequencer once you have built a snare to go with your kick and hi-hat The thought of little modular add-ons to drum machines is appealing to me, like swapping the snare on a real drum kit Quality videos. A nice reminder of the useful learnig on the internet
Hi Moritz, thank you for sharing all these awesome circuits here on youtube. Thats so helpfull! I started to learn about the Adauu 1463. I want to build a 24/24 matrix patchbay with filtering, etc. Infinit possibilities with this powerhouse. Im so excited :D The next project are modules, like you do. A modular synth, build by my own. Thats why im here. Greetings from germany ✌️
Awesome talk and showcase. If you are up to deep dive more into analog drums, I recommend looking at Korg KR-55, it is such well designed and great sounding drum machine, that it might be worth and also fun for you taking a look at it. All the best!
Video suggestions? I'll once again suggest the possibility of BBD based effects! They provide some of the most incredible rich sounding analog effects. Maybe something modeled after the famous Juno chorus, or some delay/reverb circuits. Maybe even make a stereo circuit! As always, a truly incredible video.
You are a hero man ! So detailed and explained with a love feeling to synths. Echt ,sau genial ! Und cooles Tattoo auf der Hand / Arm . Finde das hat echt Stil 😁
I love the trick of 'abusing' the Schmitt trigger VDDs its a very neat solution albeit not always 'predictable' (ie you cant know how different chips will react and the frequency outputs would change by differing amounts from chip to chip, but as the goal is producing noise anyways its a moot point).
Ps also first vid I've watched on this channel and 100% new sub! I always like practical examples of filter theory etc that cut away a lot of the day theory and just give useful outputs. Another youtuber (Phil's lab) does a very similar thing with DSPs which is awesome as he talks about the core maths but boils it down to simple code that has practical uses. (Not saying filter theory is pointless, it's not, it's just the maths can get..... difficult quite fast and it's a bit of a rabbit hole where every aspect of that maths isn't always needed to get the end result. Like you don't care about the phase response of any of these filters as you are trying to generate noise, and maniplute said noise, and don't really care about how that noise is altered by the filters. Whereas if you were trying to filter sensor data, it's a bit more complex as the filters do have an impact on the output signals etc...)
The noise generator is pretty interesting! I was expecting a true white noise generator, but the square wave generators actually reminded me of how periodic noise is generated on the NES or the Master System.
@@MoritzKlein0 On PSG chips like the SN76489 or the audio circuity in the 2A03 on the NES, noise is generated by using a LFSR. A LFSR generates a pseudorandom sequence of bits. It's not *truly* random as it repeats after a little while, but it's so chaotic that you end up getting all possible distances between two 1's, up to the LFSR's period length. So, despite being just a weird pulse wave with a continuously varying pulse width, the spectrum of the output of a LFSR will actually be completely flat within a period and will look like white noise but passed through a comb filter if you take a sample larger than a single period.
@@MoritzKlein0 UA-cam doesn't seem to let me post links here, but searching for APU Noise in the NESDev Wiki should give you a pretty detailed article about how it works on the NES. But, really, it's just all LFSRs. Atari took that to the extreme by taking the LFSRs in the 2600's TIA chip and making them into super flexible oscillators on the Atari Lynx and the Atari computers with the Pokey chip. It's, again, just a shift register but with several kinds of feedback you can choose from.
a shift register feeds two of its bits into an XOR which feeds back into the first bit, and the result (if the two feed points and the length is chosen correctly) is a pattern of on off states that takes a very long time to repeat itself, thus aproximating 1-bit noise.@@MoritzKlein0
Absolutely brilliant so far, I do hope you're continuing with more drums. I can trigger up to 8 from my beatstep pro. As I'm planning on a standalone drum module not modular, I've redesigned the PCB's (hope you don't mind) I really enjoy that part of the process. With no pots mounted on the boards and using a tl074 instead of the 2 tl072's I managed to get both drums so far to fit on a single 100mm x 100mm board and should be able to separate them so 50x100 each. Hopefully my layout skills are good enough and they work when the boards arrive. Thanks, for the great work so far, keep them coming.....
I know I am in no position yo make suggestions, but I just wanted to add one thing. I have always been looking for a channel/resource which covers the designing of circuits for musical instruments. So this channel is perfect. Now I just suggest that this channel can become a one-stop shop if there are also included some videos/tutorials on the working of the components, along with its theory. As in, a video explaining the textbook definition and parameters of an Op-Amp, then look at how it helps us in circuit designing by seeing how tweeking the input of Op-Amp affects the output. Similarly for Transistors, Diodes, Resistors, Capacitors........I think you got the point.
Wow this was so interesting and well explained, thank you ! Oh and "bravo", your "breadboard hihat", sounds much better than the one that is present in the original TR-606, imo ! 👍👍👍 Your new subscriber ;-)
Hi there, great video! But there is a mistake at 23:30. By concatenating filters in this way, you do not actually double the same response. What happens is that the second filter loads the first one, shifting its corner frequencies. You still get a 12db/octave roll off, but with two different corner frequencies. This means that the transistion is not really that sharp, but quite gradual instead. One corner is actually at 9kHz, meaning that in that case you quite significantly attenuate the signal of interest. The other shifts down to 1.3 kHz, so it is not as aggresive at attenuating lower frequencies. This is not your final circuit anyways as you add the loop later in the video, but how properly to concatenate filters is maybe quite relevant in other situations.
yeah, you're right. i covered this issue in my dedicated videos on filtering, but left it out here in the interest of time. maybe should've added a small disclaimer though!

its a great time to be alive
As an electronics student, this is the kinda stuff that keeps me going. Thank you.
Your videos are so entertaining, educational and well-put together! I am nearly done with my bachelors in Electronics and I am still learning so much from watching these!
glad to hear - good luck with your degree!
This is so amazing! I did some EE as part of a CS curriculum but have never gotten the time to get into analog synthesis
Your videos are just perfect! Even someone like me understands what's going on. Good balance between education and entertainment.
those prophet chords were amazing
So cool. Simple off-the-shelf components, none of these tricky MCUs and obscure ICs here!
This is better and more informative than all the courses about PCB Design I've seen (I just started out and want to learn about electronics engineering)
Amazing video, as always! I can't believe how much I've learned from your videos alone.
I thought this could be useful information to share for anyone watching: for this inverter oscillator topology, I've read the frequency can be reduced to f = k/RC where k is a constant that varies according to chip model (in your case the 40106). I did a quick test to see if this formula holds for the values you've shown and I've found k = 1.2. You could technically pick various combinations of R and C and measure the output frequencies and figure out experimentally the constant for the specific chip you're using, if you ever decide to go for another hex inverter chip and circuit simulation isn't an available option (for whatever reason).
Looking forward to your next video. Cheers!
that’s a great tip, thanks for sharing!
At some point the hi-hat was sounding almost like a snare! I guess the same schematic can be reused for this purpose.
Thank you for the exciting video!
I just finished building this 30 minutes ago. I've just tested it and checked that everything works and played with it together with a couple sequencers and a rd-6.
I have a Kosmo-modular i built myself and that is the only modular synth i've ever had. So this is the first time i even try a dedicated hi-hat module. I have had Moritz kick-module in my setup for a while though. A lonely drum waiting for his friends though come around 😊.
The first thing i noticed while trying it out is how versatile it becomes with the cv-ins. It started to groove like a whole samba-carneval very fast. You know? When a hi-hat with a bit of nuance become more groovy than a full kit.
If you want to make something very specific and control the details in what happens, you can. And on the other side you can just let things happen by themselves and they will.
I like it a lot actually. It's really cool and a great tool. It sounds great and can do a lot.
I didn't build it from the kit btw. I made my own module in Kosmo format and made the circuit on Vero board from the schematic.
Thank you very much Moritz! I love your work!
oh wow, thanks for the feedback - glad to hear it works so well for you!
Hi @JimmyHagerstrom, I was just about to start testing the circuit on my breadboard, then redraw the entire schematic on a stripboard. Although I love this exercise, would it be possible to share your work? Perhaps on the LMNC Forum?
@@hugoeymard-duvernay3210 I´m sorry for the late answer Hugo. I saw that you had tried to contact me about this via e-mail but i didn´t see it until recently. I have mailed you the material i have on it, i hope you got it!
@@MoritzKlein0
I still love it, it´s great. I use it with Juanito Moores 808 Kick, Eddy Bergmans verolayout and a 909-snare from a channel named Meebilt that designs and share his eurorack module designs. I really like how those three interact together.
I still haven´t figured out how to get my MK-Kick to work though. :-)
iv always been interested in how analogue hihats where made. thankyou so much for this explenation
oh thats wild that your designs are available through Erica synths.
I got started on Synth DIY with their Polivoks DIY modules about 10 years ago.
I love the way you talk through the design.
I'm waiting on a breadboard so I can try building some of these myself.
love your videos. The content is great, but the carpet and the plants make you feel cozy while learning about electronics :)
Great work!
For fun and out of pure curiosity, try recording the sound of a pulsating garden sprinkler on a calm day. By turning it into a sample, adding it as a layer underneath, and modulating it, you can also achieve an interesting effect with natural ambience . btw.170 thousand views and 9 thousand likes.
You people really have no shame ;-)
Instant sub! I loved watching this and all of your explanations are bang on! Bravo!
wow, the tone of that hat really reminds me of Lorn.
You lost me after 7 minutes but
This has been 40 years in the making. Thanks for walking us thru, whatever this is
Really, makes me really appreciate what ever is going on here!
The last bandpass filter really turns it from an unrecognizable sound to a hi-hat sound.
you mean the resonant highpass?
that crackle and the 6 osc alone could make for a great ambient module.
here's a little synth that's just like that:
ua-cam.com/video/YTczh0cTGfo/v-deo.html
if you play around with the signal’s volume before it enters the VCA, you can get some varying levels of crackle!
❤As an owner of an Arturia DrumBrute Impact it is facinating to see a lot (understand a little😅) of what is happening to make the sounds.
You could use something like an Arturia DrumBrute (if you can borrow one) as a sequencer once you have built a snare to go with your kick and hi-hat
The thought of little modular add-ons to drum machines is appealing to me, like swapping the snare on a real drum kit
Quality videos. A nice reminder of the useful learnig on the internet
i plan to create a custom sequencer for all my drum voices (and make a video about it, of course)!
what a beautifully produced video!
Hi Moritz, thank you for sharing all these awesome circuits here on youtube. Thats so helpfull!
I started to learn about the Adauu 1463. I want to build a 24/24 matrix patchbay with filtering, etc. Infinit possibilities with this powerhouse. Im so excited :D
The next project are modules, like you do. A modular synth, build by my own. Thats why im here.
Greetings from germany ✌️
SHEEEEESH. That opening track is killer.
Great video Moritz, you've talked about how much effort has gone into this design and it shows. Love the sound of it.
This is godlike. Wish I had the discipline to learn these skills.
Sehr schön! Bei deinen Videos lernt man wirklich ne Menge, weil du es echt gut erklärst
DUUUDE! NEVER EVER shut down this channel! DAMN!
First video I've seen from your channel. Immediately subscribed
NEW MORITZ VIDEO!!!!!
ausgezeichnet.
What a fantastic video! The way you explain and show everything is awesome. Thanks, subscribed
Moritz Klein low key the diy synth god
Awesome talk and showcase. If you are up to deep dive more into analog drums, I recommend looking at Korg KR-55, it is such well designed and great sounding drum machine, that it might be worth and also fun for you taking a look at it.
All the best!
the king is back !
I love how this video starts like "Here's what my hi-hat circuit sounds like -- surprise, it's an entire track!"
Why does your videos motivate me to make one of those
extremely impressively made video
Thank you!
Video suggestions? I'll once again suggest the possibility of BBD based effects! They provide some of the most incredible rich sounding analog effects. Maybe something modeled after the famous Juno chorus, or some delay/reverb circuits. Maybe even make a stereo circuit! As always, a truly incredible video.
BBD has been on my list for a long time - i’ll tackle it at some point, i promise!
well I'm going to try this out with my moog grandmother no cap@@MoritzKlein0
also this videos was cool😎😎 no cap @@MoritzKlein0
You are a hero man ! So detailed and explained with a love feeling to synths. Echt ,sau genial !
Und cooles Tattoo auf der Hand / Arm . Finde das hat echt Stil 😁
How do we cure cancer?
This man: "Simple."
You are such a good teacher and explain everything so well! Thank you so much for these videos
Great video. It was interesting to listen and observe the technical theory. And the final result is wonderful.
Good job 👏
Damn I love this channel so much…
i love you too!
Legend, I really love these synth-effect-from-scratch videos with such great expansions of how they work!
Fantastic video as usual! So clearly presented, and I love your animations! For video ideas, a rotary dj mixer series gets my vote!
I love the trick of 'abusing' the Schmitt trigger VDDs its a very neat solution albeit not always 'predictable' (ie you cant know how different chips will react and the frequency outputs would change by differing amounts from chip to chip, but as the goal is producing noise anyways its a moot point).
Ps also first vid I've watched on this channel and 100% new sub!
I always like practical examples of filter theory etc that cut away a lot of the day theory and just give useful outputs.
Another youtuber (Phil's lab) does a very similar thing with DSPs which is awesome as he talks about the core maths but boils it down to simple code that has practical uses.
(Not saying filter theory is pointless, it's not, it's just the maths can get..... difficult quite fast and it's a bit of a rabbit hole where every aspect of that maths isn't always needed to get the end result. Like you don't care about the phase response of any of these filters as you are trying to generate noise, and maniplute said noise, and don't really care about how that noise is altered by the filters. Whereas if you were trying to filter sensor data, it's a bit more complex as the filters do have an impact on the output signals etc...)
the intro made it POP omg
The noise generator is pretty interesting! I was expecting a true white noise generator, but the square wave generators actually reminded me of how periodic noise is generated on the NES or the Master System.
interesting, do you have a link that describes how that worked? the articles i'm finding are all really cryptic
@@MoritzKlein0 On PSG chips like the SN76489 or the audio circuity in the 2A03 on the NES, noise is generated by using a LFSR.
A LFSR generates a pseudorandom sequence of bits. It's not *truly* random as it repeats after a little while, but it's so chaotic that you end up getting all possible distances between two 1's, up to the LFSR's period length.
So, despite being just a weird pulse wave with a continuously varying pulse width, the spectrum of the output of a LFSR will actually be completely flat within a period and will look like white noise but passed through a comb filter if you take a sample larger than a single period.
@@MoritzKlein0 UA-cam doesn't seem to let me post links here, but searching for APU Noise in the NESDev Wiki should give you a pretty detailed article about how it works on the NES.
But, really, it's just all LFSRs. Atari took that to the extreme by taking the LFSRs in the 2600's TIA chip and making them into super flexible oscillators on the Atari Lynx and the Atari computers with the Pokey chip.
It's, again, just a shift register but with several kinds of feedback you can choose from.
a shift register feeds two of its bits into an XOR which feeds back into the first bit, and the result (if the two feed points and the length is chosen correctly) is a pattern of on off states that takes a very long time to repeat itself, thus aproximating 1-bit noise.@@MoritzKlein0
Going crazy bruh I love it
this video is done amazingly! really appreciate all the detail and animations
Absolutely brilliant so far, I do hope you're continuing with more drums.
I can trigger up to 8 from my beatstep pro.
As I'm planning on a standalone drum module not modular, I've redesigned the PCB's (hope you don't mind) I really enjoy that part of the process.
With no pots mounted on the boards and using a tl074 instead of the 2 tl072's I managed to get both drums so far to fit on a single 100mm x 100mm board and should be able to separate them so 50x100 each.
Hopefully my layout skills are good enough and they work when the boards arrive.
Thanks, for the great work so far, keep them coming.....
Amazing channel dude this stuff is sick - gonna be trying this
I know I am in no position yo make suggestions, but I just wanted to add one thing.
I have always been looking for a channel/resource which covers the designing of circuits for musical instruments. So this channel is perfect. Now I just suggest that this channel can become a one-stop shop if there are also included some videos/tutorials on the working of the components, along with its theory. As in, a video explaining the textbook definition and parameters of an Op-Amp, then look at how it helps us in circuit designing by seeing how tweeking the input of Op-Amp affects the output. Similarly for Transistors, Diodes, Resistors, Capacitors........I think you got the point.
my older videos (particularly the VCO, VCF and Mixer videos) have a lot more info on how basic components work!
@@MoritzKlein0 oh, thanks a lot. Just subscribed recently. So had no idea of that already existing.
Thx a lot Moritz, fantastic content again, very clear explanation!
thanks for watching!
didn't understood much, but got me interested until the end. Very cool and will probably start with your diy vco series
Incredible video, I wish all electronic videos were like that (and also those about antennas)
Wow this was so interesting and well explained, thank you !
Oh and "bravo", your "breadboard hihat", sounds much better than the one that is present in the original TR-606, imo !
👍👍👍
Your new subscriber ;-)
thanks, glad to hear :)
SOUNDS SO GOOD. MASTERFULL AS ALWAYS!
I built a similar hat module back when I was starting that was oddly like this one.
Props. I hope my music channel some days is as popular.
Hi there, great video! But there is a mistake at 23:30. By concatenating filters in this way, you do not actually double the same response. What happens is that the second filter loads the first one, shifting its corner frequencies. You still get a 12db/octave roll off, but with two different corner frequencies. This means that the transistion is not really that sharp, but quite gradual instead. One corner is actually at 9kHz, meaning that in that case you quite significantly attenuate the signal of interest. The other shifts down to 1.3 kHz, so it is not as aggresive at attenuating lower frequencies. This is not your final circuit anyways as you add the loop later in the video, but how properly to concatenate filters is maybe quite relevant in other situations.
yeah, you're right. i covered this issue in my dedicated videos on filtering, but left it out here in the interest of time. maybe should've added a small disclaimer though!
