Using Filters as Waveshapers 

Great video, opens up a lot of possibilities with pure analog gear

Hey, modular noob here! Started my rack about a month ago with MI utilities (Stages, Blinds, Frames, Links, Marbles) and Plaits and Ripples arrive today, with Bitbox Mkii on the way. There is no modular scene where I live, I'm totally on my own in it. Videos like yours and others are essential for learning from. Thank you! Given that ripples arrives today, I'm looking forward to learning how to use it for things other than the standard cutoff. I really didn't realise it could actually change the sound so much as well as just strip it back. Lots of new ideas to try! Edit: Oof! Well, a few hours actually on the rack changes a whole lot of my previous ideas. Lessons learned, #1 - Envelopes don't just change oscillators, they also change filters, and if you leave the sustain open too long, the resonance feedback blows through the roof. That never happened on my desktop subtractive synth units, they always did the math and attenuated the envelope before resonance increased, which I guess is why people always say "Ooh, the volume drops when the resonance goes up." Yeah, now I know why. Fuck me, modular forces you to learn fast.

Wow I never thought of a filter like this! This is exactly why I need to get DATA. Seeing what different things do to wave shapes really helps me conceptualize how everything works and what exactly is going on..

This is awesome!

Cool patch, I often do something related but use a wavefolder in place of the second filter. Then by using very simple waveforms like triangle or sine (yup, I’m filtering a sine wave) the resonance of the filter (tracking pitch as you’ve done here) gets ‘folded into the fundamental frequency’ and complicates the timbre. 👍 great for really organic cello/woodwind kinds of tones👍 it shows up in lots of my videos🤓

I tend to do this on the Andromeda... First filter is SEM based, then you could route it to VCF2 which is Moog type. You can do all kind of Filter modulation on both of them, but I do mostly on VCF1... Filter FM , different filter types, noise modulation, etc and then send it to VCF2 for normal filtering duties. Great technique.

Really cool concept beautifully illustrated. Cheers Chris

Very cool, thanks for the idea, Chris!

This is awesome, well done

Brilliant, as always, and very useful. Thanks!

Great use. I have a spare in my rack. 👍

Excellent tutorial, Chris. I would love see a few on the Harvestman/IME modules like Hertz Donut and Stillson Hammer. Love the Doepfer SEM filter it came in my starter Doepfer A100 modular system and one fun thing to do is to make it self oscillate by cranking up the resonance and level.

Cool tips, thanks for sharing.

It did start to sound vocalish!

Nice vid again!

Hi Chris, love these kind of videos you do. The one you did with the Serge Variable Q was a great one too. What software do you use for the frequency display? Cheers.

Interesting idea, but isn't this the same as patching VCO>VCF1>VCF2?
