Oscillators, harmonics, and a way to think of synthesized sound

[@brokenscart7989]

I really like the constant drone in the background. Sounds comfy

[@Timebandit1]

Just discovered your channel - it's a goldmine!

[@SoundVoltage]

Thank you so much! I'm hope it's helpful.

[@diymodularsessions6984]

It’s amazing how the world works - clearly based on simple mathematical principles overlaid on one another to form more complex patterns. Love it! Thanks for the videos!

[@nopenottelling]

AWESOME video and explanation; thank you! Among other things, I really appreciate that you took the time to actually add in a decently huge number of harmonics to the waves so that they’d actually turn into the final waveform instead of just doing the obligatory 4 or 10 and then telling me to trust you that it’d totally become the final wave eventually you swear

[@omnidivergence9846]

I just watched this again. The videos from this channel are so well put together its like attending university (probably better then that).

[@SoundVoltage]

Thanks! My tuition fees are definitely lower :)

[@michaelbishop.]

Just about understood this,which was a shock. Brilliant.

[@SoundVoltage]

Excellent!

[@DemMusel]

very interesting.. It is also quite astonishing how different OSC can sound on different analog synths and whether they are mono or poly. the used envelope can also have a massive impact on the sounds when used for classic sync Leads. My take-away is to experiment more with inverting waveform signals when using OSC sync.

[@rhampton1914]

I really like these educational videos that you do.

[@SoundVoltage]

Thanks! You're a big part of why I started these videos, so it's partly your fault :)

[@cmyk8964]

Power chords (very important in rock/metal guitar) are a part audio illusion, part distortion trickery, to make the sound sound lower. This is typically done by playing the root, the fifth, and the octave, which approximates a 2:3:4 ratio. This makes the sound wave repeat in a cycle the LCM of the individual wave period, which is half of the base note. Especially when you apply distortion to add higher harmonics and increase energy, it sounds like one note an octave down.

[@taidi4038]

Very interesting Video! I really like how well you visualized the construction of the classic waveforms with the increasing number of harmonics. The weirdly distorted sine wave output of the nonlinearcircuits oscillator is most likely not your fault ;-) Many analog oscillators don't accually generate a true sine wave, but rather use triange or sawtooth wave at it's core and distort it into a sine wave (In fact not sure a single analog synth with a true sine wave generator even exists). The circuit in the NLC CEM3340 VCO is a very simple sine shaper that only uses clipping diodes, which is simple to build and uses fewer components, but is also less precise and is missing trimpots to fine-tune the shape of the sine wave.

[@superultramegarobot]

Not to be argumentative, but there are plenty of ways to create pure analog sine waves, generally using feedback and integration - many oscillating circuits wish to produce sinewaves as their natural response, since this is the response of an undamped 2nd-order differential equation (for example, consider the Wein Bridge oscillator). Just thought I'd share.

[@taidi4038]

@@superultramegarobot Yes you definitly have a point. The main issue with many of those circuits is controlling the frequency accurately with voltage, which is why it's uncommon among analog synths. But now that I think of it, you could argue that a self-oscillating filter is a pure sine wave generator.

[@synthseeker]

Teachers are a blessing to the world. Carry on. ;)

[@samliske1482]

Man, these videos are really reigniting that love of synthesis I had when I got my minilogue at the beginning of college. Keep it up!

[@chinossynthesizer705]

Addictive synthesis is very interesting the Dk synergy was a fm and Addictive beast from 1982. And the synthclavier regen has addictive synthesis.

[@omnidivergence9846]

Modular is a great exercise in problem-solving. This is another fantastic video. Keep up the good work.

[@SoundVoltage]

Thank you!

[@aripent]

If you've ever played a B3, then you definitely have dealt directly with additive synthesis

[@pentalogue_tridecalogue]

Sine wave: Presence of harmonics: one First harmonic volume: 0 dB Semisine wave: Presence of harmonics: all harmonics of the series of natural numbers First harmonic volume: -1.82 dB Tilt volume by harmonics: -12.04 dB / oct Triangle wave: Presence of harmonics: all harmonics of a series of odd numbers First harmonic volume: -1.82 dB Tilt volume by harmonics: -12.04 dB / oct Sawtooth wave: Presence of harmonics: all harmonics of the series of natural numbers First harmonic volume: -3.92 dB Tilt volume by harmonics: -6.02 dB / oct Square wave: Presence of harmonics: all harmonics of a series of odd numbers First harmonic volume: +2.10 dB Tilt volume by harmonics: -6.02 dB / oct

[@enthaerter]

Thank you for another excellent learning video

[@ickebins6948]

This is sooo good. Thanks for sharing this!

[@thespacekyd]

It's pretty funny cuz I ended up doing pretty much the exact same experiments and went into how different distortion curves add harmonics. One thing I would really like to learn about is how distortion can effect things like saw waves and how we might be able to predict those harmonics. If I remember correctly it's called harmonic modulation theory... maybe you know what I'm talking about. Would love to see a video on that if you do

[@FriedlichNische]

I absolutely love your videos! So much information packed in and even though I have to watch them at least 3 times to understand you do a fantastic job breaking down these concepts. Thank you!

[@SoundVoltage]

That's how I boost my view counts, making people watch them 3 times each. :)

[@FriedlichNische]

@@SoundVoltage haha great plan!

[@j0KZZ]

Pure gold, keep it up cap!

[@electricdawn2258]

Very nice educational video. Well done! The only thing that was missing was how your prime number wave sounded. That would've been interesting. :)

[@SoundVoltage]

Thanks! I am not a big 'KZbin Shorts' fan, but I'll figure out how to turn that into a WAV file and post it :)

[@stroads.]

This is taking me back to audio and acoustics class, and it's exactly what I needed right now, as I really wasn't paying attention then. I'm trying to get into Eurorack, and I've been watching you for a while, despite a lot of your videos going way over my head. Will you be continuing your "Eurorack patching for beginners" series at all?

[@SoundVoltage]

I definitely could come back to that -- the first one didn't really get watched all that much for some reason, but I do like doing videos for people just getting into things. Are there any topic in particular you'd like to know more about?

[@stroads.]

@@SoundVoltage oh, well I'll definitely try to share your videos a lot, I think there's definitely an audience for that type of content. But yeah, just literally exactly the route you were going with that first vid. How to route pretty standard/starter setups, that sort of thing.

[@LarsBjerregaard]

Great demo and explanation! For bonus points you could include the pure even harmonics waveform, e.g. Befaco EvenVCO. I don't know why it's so rarely used, I find it quite pleasant.

[@SoundVoltage]

Thanks! And I had no idea that was why it was called the Even VCO! I think I have the PCB/Panel set for it sitting in a drawer, now I have to build it.

[@LarsBjerregaard]

@@SoundVoltage It's a wonderful VCO.

[@AaronNickols88]

Your making me wanna synth

[@angharadweeks9242]

This is such a great video!!!

[@SoundVoltage]

Thank you!!

[@snörre23]

Haha, i would love to have a second Mordax Data, looking at whats happening is very often all i do with modular.

[@LeoPerantoni]

Lovely!

[@SoundVoltage]

Thank you!

[@davecgriffith]

Very interesting!

[@GareyKennebrew]
