Electronotes #86 had a circuit idea of combining an envelope generator with a resonant filter to create additional detail (namely, resonant bounces) in the envelope's shape. I finally got around to making a video demonstrating this technique, with two different filters (Random*Source Serge Variable Q VCF and Doepfer A-125 VCF5 Wasp Filter).
00:00 explaining the patch
01:13 using a DC coupled filter
04:35 using an AC-coupled filter
08:03 playing with inverted transients
09:58 using different filter modes
12:34 repeating the experiments with a different filter
My Patreon supporters got additional patch tips and advice:

Later I will release a movie for the Sly Grogan - a module from nonlinearcircuits based on the original Electronotes circuit.
Technical note: Yes, the keyboard camera was malfunctioning. I treated the video the best I could so you could see my key depressions. It's already been fixed for the Sly Grogan video.

Very enlightened use of a filter. Indeed the beauty and flexibility of modular. Thanks 🎉🎉🎉

Cool, damn so many things you don't think about doing...

@EphemeralTao 5 лет назад

That was one of the most interesting and useful modular tutorials I've encountered here. Going to have to try that out with my IME Polivoks and Metasonix R-52 filters. Should be good for some really weird envelopes.

love these videos about how to get complex waveforms/envelopes/lfos, thank you!

@auctor11 5 лет назад

Amazing! Thank you so much for a fantastic tutorial!

@b_r_i_z_z_y 5 лет назад

All your videos are amazing and really helpful! Thank you!!

@MarcoGualtieri Год назад

Really excellent demonstration!

@LearningModular Год назад

Glad you liked it!

@mixolydian2010 5 лет назад

Neat, will definitely give this one a try with my variable q. I'd have never thought of this. Cheers now I can use the switch too.

@sharonsr 5 лет назад

Thanks for tutorial, going to try this today

@jeffreyevergreen 5 лет назад

Agreed, such a sweet tip! Cheers

@danieljackson3868 5 лет назад

this is great. i'm gonna try it this evening.

@wraggal 5 лет назад

Nice, I was using a vca controlled by LFO to get not as good results, great tip

@vinylarchaeologist 4 года назад

Most excellent.

@ComparativeIrrelevance 5 лет назад

Great idea!

@ComposerMichaelDow 5 лет назад

Nice idea to add just a subtle hint of difference to an arped sound!

@WiredBrain 5 лет назад

Cool trick ! Curious to try this with my Dr Octature and see how the different phase output might influence the results.

@tluth 5 лет назад

I really like the character this adds to the voice. Some remind me of the attack of a horn, while others are much trickier to describe. I will have to try this idea using the Dot-Com modular.

@LearningModular 5 лет назад

Yes - you can definitely use this trick on any type of system.

@Quantumspace23 5 лет назад

Just brilliant!

@LearningModular 5 лет назад

Thank you for your support - I really appreciate it.

@PatchMonger 4 года назад

Fantastic tip thank you very much

@LearningModular 4 года назад

You are very welcome - it's an interesting little trick from "the old days" that you don't see discussed much.

@PatchMonger 4 года назад

Learning Modular yes that’s right. I got too much into the “new” digital modules so missed some basics. Now exploring analog possibilities. Your videos are gold thank you

@chridmeister 3 года назад

Damn, just when I thought I had enough filters...

@LearningModular 3 года назад

Ha ha! Well, consider it something to do with the filters you're not currently using on a patch. Along with another video I have elsewhere on using filters as wave shapers.)

@vgermuse 5 лет назад

Genius!😍

@LearningModular 5 лет назад

That means a lot coming from you - thank you!

Wow!

@danieljackson3868 5 лет назад

wish more manufactures would be clear about whether their filters are DC coupled though

@blitbleep 5 лет назад

Nice! Isn't that kind of the same as mixing the adsr with an sine lfo?

@LearningModular 5 лет назад

The differences are it re-synchronizes on each envelope start (and again at the end of the sustain, if you have a sharp release), plus it's damped and dies away on its own (unless you have feedback turned up very high).

@christophermarney777 4 года назад

And to think I thought you were trying to make bongos

@KiR_3d 5 лет назад

Wow, I've had this idea about the same time! Now I'm watching this video. But never tried yet. OK, it's interesting, keep watching... What's the difference between this method and an additional (to the envelope) sine LFO attenuated with the same envelope? Although... making a simple MS-20 clone is easier than some LFOs. I must admit :) Also it will have the whole range of frequencies. It's hard to make with a simple sine analog LFO. WASP sounds more interesting! The cons: not all filters have an equal resonance amount over the whole freq. range.

@LearningModular 5 лет назад

The differences are: - the sine is synchronized to start with the envelope - you can adjust the damping period (the resonance amount) separate from the envelope times

@vampiresforesl 2 года назад

Very cool! I didn't understand switching to highness output, though. The author said it "Acted like" an AC-coupled filter? Wouldn't an AC-coupled filter ignore an envelope?

@LearningModular 2 года назад

At the moment an envelope changes level, it is now (briefly) AC - not DC. And a sudden spike actually contains a very wide range of harmonics, from low to high, to build that steep spike. The "AC coupling" is actually its own filter on the CV, with a cutoff frequency (usually very, very low); that cutoff determines how many and which of these harmonics get through.

@ComposerMichaelDow 5 лет назад

Could you then send the affected envelope out to a frequency divider to get a slower warble from the resonance?

@ComposerMichaelDow 5 лет назад

I guess then you may aswell have an lfo's wobble sent to be mixed with the envelope, but have that LFO sent to a VCA which is being plucked by the same gate/envelope, so that only the initial attack is affected....

@LearningModular 5 лет назад

First, the good news: All you need to do to slow down the warbles is to reduce the filters's cutoff frequency. Some filters - like the Wasp filter used for part of this video - have a limited frequency range from their front panel knob; sending a negative voltage to one of their frequency CV inputs can help tune them lower. As for using a frequency divider, normal frequency dividers are binary - they are either on or off, and are meant for dividing clock signals or square waves; they won't work to reduce the pitch or frequency of a more complex analog signal. You would need a frequency shifter to change the frequency of an analog signal.

@decapitateallcops3214 5 лет назад

Will this also happen to an envelope in VCV and Soft Tube?

@LearningModular 5 лет назад

That's a very good question - it would be an interesting test of just how good their analog emulations are. If you get a chance to try it, please let us know!!!
