Synthesized, analog hi-hats are pretty fascinating. That’s because emulating any kind of cymbal using an analog circuit is tough, since the sound a real cymbal produces is not quite pure noise - but also not really harmonic.
Still, a couple classic drum machines like the Roland TR-606 and TR-808 took their best shot at it, with quite strange sounding results that I personally really like. So I decided to follow suit and came up with this simple, but very versatile and crunchy sounding DIY hi-hat circuit. If you want to build along, here's the bill of materials:

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.
bro, wait for oscillators at least, don't judge by just filters and amplifiers. It will become more interesting next semesters
Can I ask you a question? What specialty do you study at the university?
@@user-vd1ss8rl2dI’m not him but you study all these topics in depth in electrical engineering courses
I’m working towards a computer science degree and been thinking of changing my major to EE as this seems so cool to me and I happen to love music too.
@@user-vd1ss8rl2dI’m a computer engineer, but my school has a lot of overlap with electrical engineering. I’ve done research with FPGAs, and have a VLSI internship in May.
i am never going to unhear the square waves in hi hats oh my god
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.
@@ross302ci 808 cowbell is made out of saw waves
Dude that "demo" was unironcally a fckn bop. For the love of God please make a full version
thanks, will see what i can do!
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.
drum machine would be amazing once all voices are done!
@@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 I'd love a simple trigger sequencer with multiple lanes to trigger the drums
Gonna have to second the Drum Machine idea. Each voice being built is so cool to see! @@MoritzKlein0
@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 love the contrast between the concrete background and the rug with the plants
...concrete *floor... ? ;)
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.
yeah mate just followed all your steps to a tee and built it myself. it worked wonderfully
This is excellent. I wish that my EE teachers 30+ years ago had made it this interesting.
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!!
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!
they had some wild ideas, that’s for sure :)
@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.
SOUNDS SO GOOD. MASTERFULL AS ALWAYS!
this video is done amazingly! really appreciate all the detail and animations
Legend, I really love these synth-effect-from-scratch videos with such great expansions of how they work!
Fascinating! I had no idea so much complex sound design went into a high hat sound. Very well explained, too. Thanks!
This video is AWESOME. Thank you for the complete, precise and intuitive explanation, combined with audio samples at each stage of development!
Absolutely fantastic!
what a beautifully produced video!
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
What a great video! Very well made and your explanations are wonderful, thank you so much!
Amazing work!
Your presentations are very clear, concise and informative. Thank you Sir and keep up the world class genius produced videos!
Incredible content. I'm amazed by your knowledge of analog music. Truly astonishing !
Absolutely wonderful video thanks for making this public 💪🏼🙏🏼
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 👏
Sehr schön! Bei deinen Videos lernt man wirklich ne Menge, weil du es echt gut erklärst
Great video Moritz, you've talked about how much effort has gone into this design and it shows. Love the sound of it.
Brilliant. Subbed and look forward to viewing all your other videos.
such a great video and concise explanation, 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.
iv always been interested in how analogue hihats where made. thankyou so much for this explenation
These are far and away the best explanations of analog audio circuits I've seen. Thank you!
New moritz klein video - great way to start my day
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
Sounds fantastic
Excellent explanation and implementation. Great work! 👍😀
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
These are really cool!
That hi-hat sounds killer
As an electronics student, this is the kinda stuff that keeps me going. Thank you.
Fantastic video as usual! So clearly presented, and I love your animations! For video ideas, a rotary dj mixer series gets my vote!
Amazing content! So cool! Well presented!
First video I've seen from your channel. Immediately subscribed
extremely impressively made video
Amazing channel dude this stuff is sick - gonna be trying this
I love your channel!!! Thank You
so much
So happy I subscribed. This is so great for learning about circuitry. Also, what a cool way to learn!!!!
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.
This is perfect!
Your videos are just perfect! Even someone like me understands what's going on. Good balance between education and entertainment.
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
Thx a lot Moritz, fantastic content again, very clear explanation!
thanks for watching!
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!
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)
You explain so great
Thank you!
incredible.
Nice work!
Lovely work on this M K !
Ich hätte bei den zig aufkommenden Problemen nur mit den Schultern zucken können. Du: „Einfach!“. Meisterhaft!
love your videos. The content is great, but the carpet and the plants make you feel cozy while learning about electronics :)
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.
glad to hear!
Why does your videos motivate me to make one of those
Going crazy bruh I love it
This fantastic!
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!
So cool. Simple off-the-shelf components, none of these tricky MCUs and obscure ICs here!
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!
Incredible video, I wish all electronic videos were like that (and also those about antennas)
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.
I could nerd out on this its ace learning ❤❤
@MoritzKlein0 This is amazing, you explain things in a way that I can understand. Thank you for taking the time to show the steps and thought processes.
for future videos, I would really love to learn about an echo / delay methods, and update us some time on how your synth is coming along.
delay is on my list, should be coming sometime this year!
didn't understood much, but got me interested until the end. Very cool and will probably start with your diy vco series
amazing 🤩
its a great time to be alive
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 😁
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!
SHEEEEESH. That opening track is killer.
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!
Great video!
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!
Oh this is a way better design than my recent one using a white noise chip and a vactrol LPF + JFET as the dynamic element
amazing!
the intro made it POP omg
This is godlike. Wish I had the discipline to learn these skills.
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.
sweet, let me know if you run into any issues!
the king is back !
Instant like. This is one of my favorite series as a musician and DIY electronics tinkerer. Top notch editing and beautiful music production.
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.
i'm mostly using WIMA film/foil capacitors. they're great.
@@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 don't mind paying but I haven't made many audio circuits but I'm familiar with all the theory. You're an amazing teacher. I love filters. I'll join your patreon when I get paid tomorrow. 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 a retired first responder with ptsd but I have a technical academic background and I've been obsessed with circuit theory and music the last 4 years. I also donate electronic learning kits to anyone who asks. I have tons of components just not audio quality caps. I just sent a kit to a guy in Virginia 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 I just ordered a bunch from the US. The conversion wasn't kind but I have all the other components. Thanks man.
@@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'm not worried about getting extras, I believe your work that's already public is worth my support and you getting it without patreon taking a bunch off the top. 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.
Masterclass! 😎💯
wow, the tone of that hat really reminds me of Lorn.
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!
glad to hear, hope you'll enjoy this one too!
Just watched it, it was awesome!
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.....
that crackle and the 6 osc alone could make for a great ambient module.
here's a little synth that's just like that:
th-cam.com/video/YTczh0cTGfo/w-d-xo.html
if you play around with the signal’s volume before it enters the VCA, you can get some varying levels of crackle!
Awesome.
This is so cool! I wish the days had six hours more so that I could experiment with stuff like this
NEW MORITZ VIDEO!!!!!
ausgezeichnet.
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.
I’ve been really into the 909s lately
Excelente.... !!! magnífica explicación...
Sounds better than my arturia drumbrute impact 👍
