Stay Noisy!
Very cool. I like your videos. Most TH-camrs are too excited in their videos or they fall asleep while talking but you do a great job.
Ha! Thanks!
I once worked for a Dutch synth company that went bust pretty quickly. The synths we built used the CEM33XX series. After the bankrupcy I personally built as many synths from the remaining parts for a con man that had bought all the parts but did not pay me in full. Sweet sour memories from the start of my working life..
Oh boy, sounds rough!
@@QuincasMoreira It was a good schooling in who to trust and who not😉
I'm currently building a synth with all these new versions of the old CEM33xx chips. It's fantastic that they are available again! This module is great and very cheap for only €99
where did you find it 99eur bro?
@@ChristosA3 Correction it's 99 dollars. First link in the discription.
Even better that you can get the sub module for 25bucks to just add a full analog vco to a module.
I guess I'm gonna get some and build some voices.
I have been wanting to build the 5u version since I found them a few months ago. I’m glad you reviewed this. I’ll have to get a few of these now.
it's a super sweet VCO, highly recommended
The sine FM sounds sweet on this module!
this is a surprisingly awesome VCO, I actually didn't expect it to be so perfect, lol
I'm now a subbed oscillator
Too much fun going on here. I’m telling Mom! 🤪
“Tap that triangle” is my new band name. So what was our main take away from this video?
We each need one hundred oscillators! Fifty minimum. Just an entire giant skiff of em is my Dream. Just need to know I’m never gonna run out. One or two have a blowout... plenty left to tap!
I have some of these 3340s ready to build around. Have the 3394, too. Home brew DIY schematics are a little scary, but I’m sure I’ll tackle them soon. I hope...
Thanks for another very well made video, man!
thank you for watching and for your lively comments Chaz!
Look mom no computer did a DIY built on just that a 100 super simple oscillators, sounds like an absolute monster...
You make really high quality content. Just found you and already lovin‘ your vids! Subbed!
Thanks!
I really liked this. I bough a 3340 right away from electrosmith
Good stuff! Must be cool to build your own modules.
I have a couple of 3340s (and other 33xx chip reissues) in my parts pile. I really need to do something with them. The SH-101 sounds fine to me ;)
Someone on the synth diy sub reddit made a pcb for the 3340. If you are looking for something too do with them. Mine are in the mail looking forward too it. www.reddit.com/r/synthdiy/comments/cwq82m/cem3340_vco_schematics_and_pcb/
do it!
do you have any videos showing how you would tune a VCO that was just built? I would love to build this, just not totally understanding Electro-Smiths directions for tuning it.
I don't! but it's pretty straight forward. Use a good v/OCt reference, like a Keystep CV out or Midi 2 CV converter, and a tuner. Play octaves and turn trim pots until it tunes over many octaves.
Nice vid mate. One question, how are you getting midi from your keystep into the VCO?
No MIDI, the Keystep has CV outputs
Great video! I have been wanting to delve into the world of Eurorack for some time and am looking to build many of my first modules. Is this one of the better sounding VCOs in your opinion? The price is attractive to me and the chip is obviously a classic. I imagine they all have a different character, but I’d love to know your favorites in kit form (and otherwise)
Hey! Yes, this is as good a classic VCO as you can get, leaves nothing to be desired IMO, great place to start. Have fun!
hello I would be interested in three modules vco Electrosmith 3340 VCO, what would the total cost be with shipping included for spain barcelona? I wait your answer thank you
Hello Jose, please contact Electrosmith directly! There's a link in the video description above. Cheers!
Does this module suffer from the notorious pitch shift when changing the pulse width?
I haven't noticed it, will test
@@QuincasMoreira Thanks. I’m strongly considering buying a few of these, but only if they don’t have this issue.
@@StepDub So, I did some tests. There is a slight pitch fluctuation when changing the PW. It's barely noticeable, it had never bothered me in actual use, but yes, it's there, a couple of cents worth. I still consider it one of my favorite analog VCOs.
@@QuincasMoreira Many thanks for this research. I have been trying for months to get three MFOS VCOs not to sync when tuned to unison or multiples, without success. I’ve reluctantly come to the conclusion that the only way forward is to replace them and don’t want to swap one issue for another, and these are the top choice. Again thank you for the test and kudos for sharing your progress and experience.
@@StepDub Check out the Befaco Even VCOs as well! They are the most accurate and stable analog VCOs I have
How did you add the second sequence to the keystep @ 9:30?
I didn't , I just added notes to the same sequence
@@QuincasMoreira Ahhh, for a second there, I thought there was some keystep magic going on. Keep making great videos!
What is the oscilloscope module you have there? DATA something?
Timothy Tucker It’s the DATA utility/scope module from Mordax.
I hope they can get these kits into Thonk.
Do you think this would work in a Tangible Waves AE Modular setup? I know the power is only 5v for AEM though, so maybe not
nope, need the +/- 12v!
Seems that HardSync misses some periods (like the "bug" in Neutron's HS). One thing I don't like with CEM3340: it's too conform, sterile. Sounds almost like a DCO.
Disagree, nothing sterile about it to my ears!
I can easily make it unstable, so having the stability to start from is nice . But yeah, I agree there's something not quite right about the Hard Sync
@@QuincasMoreira OK, I'm just picky :) You can find about that HS issue in modding/hardware forums regarding to Neutron. People are fixing these schemes already :)
