There is a pretty big deference in amplitude comparison with the saw, tri and sq. waves eh ? i noticed on the schematic, 0-5, 0-10, 0-12v peaks. I built Sam's fully loaded version update with PWM and DC controls on the sq with cv in and I am noticing the volume difference a lot on mine. Hence I found you looking to compare with someone else. I guess this is just how they designed it? are you noticing the same ? also i want to add the sync's and tracking.
Xtian of Zodd I’ve noticed the differences in amplitudes for different waveforms. Yes it’s the design of the 3340, but don’t forget the harmonics. Sine waves always sound sort of muffled and very soft, since the resonant frequencies will sound off on certain multiples of the harmonics, some much less than others. Where square waves have raspy and very resonant oscillations, throughout all orders of harmonics.
Yeah, I actually was thinking the same... But I didn't hear the difference between the square and the saw. But I could make a video next week, where I address that!
Yes the triangle definitely sounds like the sine in your video. So your sine wave, if I follow, was from adjustment of a crude low pass filter made from a capacitor and potentiometer, applied to the triangle?! That’s a pretty easy sine wave implementation and it sounds great. THANKS for sharing this, good job!
Hey! Thanks for making this pcb. I actually ordered a few of your pcbs from JLC and they arrived earlier this week. I put one together today and i'm getting no output - and the chips are getting hot, espcially on the power reg side. I took a look at the schematic vs the pcb and noticed one uses TL072 Opamps and the other uses TL084. They look like the same pinout, but not sure what's intended. Also I see the schem lists diodes and what not. There might be an issue?
Yes... Fuck I know whats wrong... The schematic is the wrong one. I built the PCB with an old schematic. I forgot to mention it. I'm very sorry for that!!!!! In will just upload the old Schematic for the PCB. I though I already did this but I might forgot that! I am so sorry for that!!!!!
@@stillnotbeta898 hey it's all good, it's part of what comes with diy. Can you add both schematics to GitHub? Maybe I can fix the boards I ordered with some jumpers or cut traces. Thanks again!
@@stillnotbeta898 Thanks, i actually got it working! In the end I found out that the volt reg I used was actually pinned out backwards. I fixed that and have all the outs working now. Thanks for the schem - it helped me trace to the issue.
Hwy could you do A video on how to connect the pins to the jacks? Also If I am using a power source with a 16 pin ribbon cable, can i convert? cheers bro
Hey, i saw you had a tube module in your euro rack layout there, by chance could you do a vid on it? I’ve been looking for a way to incorporate some tubes into my eurorack, thanks!
@@stillnotbeta898 hey, I have been doing some research on this module, here is a link where I think people figured it out. lookmumnocomputer.discourse.group/t/valve-distorting-vca-problems/453/66
Hello how are you? This project is great...I only have one question...what value are the pitch and pwm potentiometers? and if you could tell me how to calibrate them ... I hope you answer me and again I thank you for sharing this info. Cheers
If i uploaded the gerber file to JLCPCB and ordered the pcb, from your github, then ordered all of the parts, the soldered them together would it work?
Hello friend, I have already received the pcb, there is a design problem in the Trimer, there are no perforations. If I drill with a drill bit I will not damage the pcb? just below I see that it has a layer of copper somewhere.
i appreciate your work, but DUDE you should route the audio of the camera and the module to a mixer. What kind of video is this, a video about audio and the WORST part is the audio. Rest assured, you are not the only one. But this is some bs
I love that you made the panel look like a Look Mum No Computer one :D
I actualy also built his filter and its also in the design scheme like this one and they look rather beautiful... :DDDDD
Really enjoyed the video. Keep it up!
Nice work. Well done!

Haha yeah, I didn't wanted to spend time on searching for a sine converter... And I actually on my newest design I don't even have a sine....

awesome! Would you be prepared to share your PCB design? I'm planning too build several VCOs with AS3340 and a PCB design would really help!
Sure!!! It's on the GitHub
amazing, thanks so much :-)
Inspiring video!

No, this is a totally new PCB and it won't have that error. :)

how much does it cost a cem3340
I paid around 8 bucks for a AS3340 at Electric Druid... But you could also look at Thonk or so....
