im trying to get a CEM3340 chip but i cant find them for under 50$ so its become a bit less affordable lol.. the super simple oscillator still is a dirt cheap build

his band in which he plays guitar would have seemed 100% normal in the eighties. I often wonder what his parents look like or listen to. maybe they listened to 60's music in the eighties and then he was born in the 90s, so there's like a lag. or it's a cyclical thing and all styles are bound to come back which is why I'm being subjected to the eighties for the second time (although this guy is totally amazing and funny). there are so many retro bands now. so you can imagine a musical universe that supports all periods simultaneously. but in just a few more decades, assuming one style per decade, it's pretty far out.
Wait, You mean I can build my own modular synthesizer in my house? What kind of wizard are you, and where have you been through all my life? Seriously, there are no words that would express how happy and grateful I am right now! Thank you very much for that, instant sub from new declared fan and disciple!
Collin Furze of synthisizers ... I didn't knew there was an osc. chip that could do 1V/oct. Some analog noisemakers don't care about 1V/oct. others used complicated exponential coverters to get it.
This is amazing. Even years after the release of the video still one of the easiest (if not the easiest) of functional DIY VCO I have seen. I am absolutely going to try and build it.
Just started a DIY Eurorack series on my channel. I'm HIGHLY inspired by you to do this. Mine's using kits, though. I'm hoping it'll be a good place for people to get started. I love what you're doing here, man. Seriously one of my favorite TH-cam channels of all time.
Hatagashira exactly! I've been saying this for years! Well...figuratively. I comment this few month ago because it's so obvious! Some kind od weird colab would be awesome!
Dude you are the best and my favorite circuit bender that I’ve seen... you are hilarious and remind me of so many of my friends... you are always welcome to stay with me or my community if you ever come to Austin Texas.
Thanks alot for these tutorials, there aren't many people on youtube that explain it in a way, that most people can understand. I was wondering if you will make some videos where you explain/show the complicated methods of making VCO's, filters etc.
MODS: ok so i put another 100k pot in series with the tuner pot, and now i can tune a much wider range; whereas I was able to find middle C and tune to that now. :D, i got the tuning pretty tight now, i can span more than a few octaves and remain in tune :D so pumped I used a BOSS TU-3 on chromatic using middle c and checking in the DAW with another voice layered over top. cheers
Man I've watched alot of your videos in my life and I didn't know you did these lessons. Here I am at 30 with 20 years of music experience wanting to make my own pedals and devices. Thank you for making this!
Just built one using the as3340. I get this weird thing where when I plugin in my beatstep pro it plays super high pitch and I cant tune it for shit. did you happen to run into anything like that? Banging my head about where I might have gone wrong.
i tried to build it with the as3340 too but i couldn't get it working... i checked, rechecked and rerechecked a thousand times the schematic and i haven't found any mistake, i also checked my components , they're good.... I'm missing something and it drives me crazy hah does anyone have tips or common mistakes not to duplicate ? (i'm a beginner if it wasn't clear enough) thxxxx
@@gillestinguely same thing for me ... I've built three of them and also onr digital to analog sequencer and the cv is totaly out of reference with the tuning ....and the scales are like in reverse ( the higher note shown on the display of the seq the lower note generated by the oscillator) suppose to be exponential but ... welll ... i don't know ....
yep like i said in the vid, i will be adding addons to this circuit, this is the core of the module, ill be including optional addons. square wave out + PWM in will be one of the add ons, only requiring another TL072, 10k resistor and a couple of jack sockets. i still need to finnesse, but you can definitely work it out if you look at the CEM3340 datasheet :)
The add on is pretty simple, a comparator on the triangle out (saw might work too?) and the width is chosen by changing the voltage it's being compared to
its even easier, check the CEM3340 datasheet, it already has square wave out, i just figured it would be a simple addone with 1 tl072 for input and output
yeah totally. would be an option later on. this just seemed easy for now, but yes. totally. when i do the square-wave one ill plop a tl074 stripboard layout in too
There's approximately one word to sum this all up: brilliant! I am going for 1V/octave because there might be three parts (MIDI-CV-MIDI, analog sequencer and the synth part obviously), keeping it standard. Always say "never", I'm not going modular, I just want an analogue mono synth with as low expense as possible.
Looks like I'll be building at least 10 of these, thanks man. Guy looks around the internet for a year trying to find an easy 1v/Oct schematic for Euro rack. Only because he forgot you were awesome. Sync would be cool though . I can picture ten synced up with a little detune😉
Thanks Sam, genius, I finally finnished my TD-616, (Twonk Drone-616 the number of the beast from the original Hebrew scriptures) using 18 of your super simple oscillators, the filters are a bit weedy, but I'll be watching your vids and upgrading them ASAP. When I get a vid of it on youtube I'll share the link. I've never built anything like this before and I wouldn't of tried if it wasn't for your inspiring and easy to follow destructional video's, keep up the good work.
Love the Channel man can't wait to give my own modular synth a shot . Been wanting to give it a go for a while, this is EXACTLY what I needed to get me to give it a go!!!
I was looking up colpitts oscillators and your video caught my eye. You give a crazy vibe, and that made me watch your whole video 😆👌🏼👌🏼👌🏼 Awesome, you really spent the time making this stuff, tape as you do, and explained too! that’s a lot of talent there👌🏼
ta-daaAAHH. made it! i now have one of the above! after hours of faffing about with it not working i tried a new op amp, worked right away. i am delighted! at a bit of a loss now as i own nothing that make 1v/oct signals for it. so i am off to make a resistor ladder push button keyboard........
Man you are my hero! I was looking info to build my own 8 oscillators Swarmatron and...found your channel. Yhis is the best possible begining ! Than you so much for so invaluable info
Lovely indeed! Sam, thank you for essential basics. Lol, i can’t even buy stripboard in my country, now i need to decide what i like less - pcb design and etching or making stripboard out of common board.
Nice one for posting this one Sam educational and fun to watch my man 👊👊. POW !!!!. Love the drill bit tip its cheaper than the supposed proper which pretty much does the same thing .
I built one !!!, mines just got some things to work out with the PWM controls not controlling very much ...yet...lol. might be a bad pot, they were pretty affordable ones. Also I built the FC power-bus as well, that went without a hitch and the sequencer is almost done as well. Keep em coming Sam!!!! were building them... ..And thank you so much for these projects! changed my life. proper procrastinator now :)
Nice, thank you very much sir! How do you know what resistor and capacitors to use? Datasheet for one, but do you calculate them for certain voltages? Longing for the rest of the series!
awesome work!!!, but i have a question. the jack have 5. Which of all goes to the pin that comes out of the schematic? Thank you very much and excuse my ignorance
Yo I am suddenly great fan of your work and I enjoy all your vids!! Simple and beautiful! I wanted to ask I have HCF4060BE Chip - would I be able to use it as base for oscillator?
Great video. Like the rest of your video's. Is there a way to play the module using a regular midi synth? Would you be so kind to make a video creating midi to cv module? that would be awesome mate.
Man, now if you could get a MIDI to CV conversion going, and did everything else in this series, you'd easily have a homebuilt synth cheaper than the ones in stores cost
I've been waiting so long for a series like this. No knowledge on electronics whatsoever, but with videos like this I'm willing to try. Got yourself another patreon! What tier gets the additional information of the extra features?

Hey dude.... you are GRREATT ...... a little (well actually a lot) more crazy than me ..... but both of us are doing ELECTRONICS and SYNTHS so I gave you a shout-out on my channel and made yours a FEATURED CHANNEL (even though I am peanuts compared to you) ....... keep up the great vids and I am you fan 🙂
LMNC is obviously a more hands on type of channel. It's basically a DIY channel more or less. I wonder, your safety pin earring, is it supposed to represent that or did you just dig the way it looked? Also, and please understand that I have a very rudimentary understanding of electronics but I know a little (very little), with those super simple oscillators, theoretically, one should be able to use a 555 timer to step them one to the next. You wouldn't get exact notes out of them but it should be a fun easy project that almost anyone could do. BTW, cool video. I like how you almost take people by the hand and show them, you can do this. You can build this stuff if you really want to. It's not THAT hard. I've been away for a little while because TH-cam in its infinite wisdom has decided for whatever reason, that my subscriptions don't have to be permanent. All hundred or so have disappeared and the new ones don't stay either. Ah well. Que sera sera. I'm glad I remembered you though. Carry on.
Hi Sam! Just build the thing. Works beautifully. I just wanna ask what resistor values do you use for the square out add-on between the pin 5 of the CEM3340 and the second TL072 ... I can't read if it's 470 ohm or 470kOhm. Thanks!
The CEM chip is using 470 ohm resistors, it _looks_ like the TL072 for square wave is using 470k ohm. You won't do any harm using 470k first to try it out.
I built my CEM3340. It works very nicely except every now and then the output goes all distorted and noisy for a few seconds before coming back to normal. It's pretty random and inconsistent. Any idea what could be the cause? Thanks in advance
Thank you for making the unobtainable obtainable to those willing to build. THIS I can afford.
im trying to get a CEM3340 chip but i cant find them for under 50$ so its become a bit less affordable lol..
the super simple oscillator still is a dirt cheap build

You're the only guy I've found who describes building a module like an announcer talks about a sports game.
This is like an alternate reality where Johnny Rotten got into analog synthesizers instead of punk rock
You mean like on Rottens work with PIL? Or his solo album?
Simon Gunkel I meant it more like that he resembles rotten
his band in which he plays guitar would have seemed 100% normal in the eighties. I often wonder what his parents look like or listen to. maybe they listened to 60's music in the eighties and then he was born in the 90s, so there's like a lag. or it's a cyclical thing and all styles are bound to come back which is why I'm being subjected to the eighties for the second time (although this guy is totally amazing and funny). there are so many retro bands now. so you can imagine a musical universe that supports all periods simultaneously. but in just a few more decades, assuming one style per decade, it's pretty far out.

A VCO on a chip? That is so awesome. I didn't know about it untill now.
Thanks for the video.
brah, you never heard of dco synthesizers? :)
The famous Oberheim OB-X used the very same chip.
This is amazing. Even years after the release of the video still one of the easiest (if not the easiest) of functional DIY VCO I have seen. I am absolutely going to try and build it.
