Hey, i still need to watch the video but I just wanted to express how grateful I am for you putting these videos online. Not only are they very interesting, clear and I'm I learning a lot but they're also perfectly timed as I was just starting to build my own synthesizers at the ending of last year. I'm super thankful for your video's though and it really gives me a better understanding and in depth view of what I'm doing and inspires me beyond the self thought diy circuit filosofy (by lack of better describing word) I started off from. (combining physics, ideas and basic systems/building blocks/contraptions to build circuits and devices) It's adding so much to my knowledge, and realizing microamps can be enough is amazing because using 4.7 nanofarad and 100kohm resistors saves me loads of money instead of using 470 microfarad and up capacitors with small resistors so I could get my volts out before I realized millivolts was an option. Anyway, long story short, I love the clear interesting highly educational video's you put out and I'm very grateful for them and it almost makes me happy corona came around so thank you very very much. Lmnc, mechanical engineering and high school physics were my basics, but this really expands on that.
Nice! If you use folding stages with different threshold voltages (different number of diodes in series), you can get the same effect with a lot fewer stages: (1 diode): 2 corners (3 diodes) => (1 diode): 8 corners (9 diodes) => (3 diodes) => (1 diode): 26 corners compared to (1 diode) x 6 to get 12 corners in the original design. The difference is that in this setup, the intermediate folding stages have outputs that go beyond the threshold in multiple places, so the folding action of the following stages is used multiple times. This might not save any diodes, but it definitely uses fewer op amps, and if you can come up with a way to change the threshold voltage other than adding more diodes in series, you could save a number of diodes as well. You can also make some funky wavefolding functions if you don't decrease the threshold by a factor of 3 in each step as I've done above, but try other combinations.
would you show us an analyze of the (Rene Schmidt's) Korg MS-filter clone, how the exponential convertor or transistor setup works and those 2 10K resistors heading to the CA3080's.
My oscillaror use this Wave mult (with kind permission from Ken Stone), the sine is normalled to the switch och the iput of the wavemult so you can use external sources if you want.
It'd be really cool if you could do an overview of the bottom part of the wave multipliers! It looks like a really unique circuit taking advantage of the LM3900 and I'd love to know how it works. It looks kinda like an evolution of the triple wavefolder circuit. It's so weird, it does full wave rectification, but somehow the output stays roughly the same volume even though there's no VCAs involved
I always assumed that Ken Stone would have the output of his circuits be tapped where they were, and with the 330R resistor in the mix, to help compensate for the voltage/gain drop that you get with the common 1K resistor hanging on the output of opamp circuits since his method adds the 330R resistor to the feedback loop of the opamp, increasing the gain, and still providing enough resistance to prevent damage if the output was shorted to ground, though I could be completely wrong on that....
I'm not sure that guitar effect distortion clipping diode do the same as the wave multiplier, the just clip the signal. I might be wrong and I may built this concept and see what does it do to a guitar signal.
I cannot thank you enough for making these public. This is just an amazing resource. Thank you from the bottom of my heart!
easily one of the best channels on youtube.
Clever way to do wave folding. Thank you for this whole series.

Thank you so much for making these public. You’re an excellent teacher, and these are exciting topics.
That intro is golden 😂

Thank you for creating and then sharing this series with the world. Very commendable.

Hah! I've wished someone would explain that circuit to *me*. If you figure it out let me know. ;)
@@Lantertronics i feared that may be the case, i'll do my best :)
Aaron Jr. was NOT the impostor.

You look younger... No, don't tell me! It's a new haircut, isn't it?

Nice haircut
Hmmmm... Something tells me that's not you... I can't quite put my finger on it... What could it be?
IS THIS IMPOSTOR FROM AMOGUS??
Ignored diodes, are sad diodes. Be kind.
