Hey synth’s addicts! I have built this vactrol vcf from Moritz Klein; it is really easy to build and it working good!! It is screaming like an acid bassline ! Catch the lazers ! Now I would to test the HP mod. I was inspired by the VCF-1 schematic from Skullandcircuits to improve the CV input. By the way here is my instabitch page of burnt circuits, engine sound, fart boxes and other noisy experiments [http://www.instagram.com/saint\_et\_moudulard](http://www.instagram.com/saint_et_moudulard) > **[VCF-1 – Vactrols – Skull & Circuits](https://www.skullandcircuits.com/vcf-1-vactrols/)** ![IMG_20210221_165815](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/2X/c/c9c6408b88d4f99e4523ce3b27d9a8524f7283ff.png) . ---

Hi, this would be better posted in its own topic, or under [Building a VCF—Moritz Klein](https://lookmumnocomputer.discourse.group/t/building-a-vcf-moritz-klein/2704) if that’s the same VCF. ---

hey guys, i’ll be doing another livestream tomorrow (2.5.2021) at 7 pm CEST/1 pm EDT. this time, we’ll try to fix my VCO’s sawtooth-to-triangle conversion. catch it here: [![](https://global.discourse-cdn.com/free1/uploads/lookmumnocomputer/original/3X/9/d/9df2d173f4018f0189753fef3a49f62aad563a1c.jpeg "Trying to fix my VCO's triangle output") ](https://www.youtube.com/watch?v=2Dbb0iW1JRk) ---

Nice one! @moritzklein was the simple “ADSR” responsible for the glide/portamento in the outro patches somehow or was that coming from somewhere else? I’m looking at doing a gated glide right now, leaning towards something like this: [http://yusynth.net/Modular/EN/DUALSLEW/index.html](http://yusynth.net/Modular/EN/DUALSLEW/index.html) But if your elegant circuit was involved maybe I’ll pilfer that instead!

no, i dialed the glide in on my beatstep – no secret magic happening there, sorry! ---
