Update from the Studio Lab 8/27/2025

Hello there. Module Availability Re-stocks: Gyrinx-VCF, Influx Mixer, Pro ADSR.

A Sequential/Oberheim OB-6 has landed in the studio. Had to trade my Juno-60 for it, but it was absolutely the right fit for me and the other party as well. This synth is definitely made for me, can't remember ever getting on so well with any synth as the OB-6 holy moly! I have quickly shaken 60 thrilling patches out of my sleeve - and when I have a full set of 100 soon I will issue my Quintessential Synth Soundset on Gumroad. Expect it will be $20, I say without ego worth every red cent when you experience some demos of what's going on here. I am also working on other sound sets like Juno-106 bank 1, and JX-3P. Thank you so much for your continued orders and support.

G-Storm Electro Announces ProADSR 3310 Dual Envelope Eurorack Module

Alfa AS3109 VS IR3109N Quick Comparison

Many have commented about my last video why I fool around w/ reclaiming the old chips when Alfa has some remakes on the market. So here's a quick comparison of the Alfa AS3109 remakes vs. IR3109N OTA chips in my 101-VCF tester module. For me the Alfa behaves quite differently with regard to signal clipping and output magnitude. Enough as to not recommend them as a 1-to-1 replacement in vintage synths and the reason I don't use them in my own modules. It's too bad, I enjoy using other kinds of Alfa chips 3320/3340/3350 in other filters and my 101-VCO.

Time-Saving Methods of Rescuing IR3109N OTAs from 80017A Wafers

Today I am sharing spilling the beans on my 80017A wafer-stripping and chip reclamation methods. Over time I have developed my own system for improving the speed and success of reclaiming coveted IR3109N SMD OTAs in decent quantities. These OTAs are used in my 101-VCF, JP6-VCF, and JU60-VCF eurorack modules. Even with time-saving measures, I easily spend way more time reclaiming the chips than actually building these modules. And the main reason I call my endeavors a labor of love, it's all for you my friend.

Introduction into Modular Synthesis 101 | Part 5 | Modulators

Continuing my introductory series of videos on Modular Synthesis 101. Today we'll look at some classic modulator utility modules in Modular synthesis with some simple examples. You already know about 2 modulators: Envelopes and LFOs. Along the way we'll be changing any Lowpass filter to a Highpass. From the last video we also know that a VCA can be used as a Modulator. So it probably won't surprise you there is a special Modulator can behave similar a VCA.

Modular Synthesis 101: Introduction

Today I give you an introductory series of videos covering Modular Synthesis 101. This course is for anyone who's been mildly curious about modular synthesizers. Maybe you've seen your favorite musician like Johnny Greenwood using a modular synthesizer at a show. And always wondered what does all this stuff do? I'm here to demystify it for you. Today we'll start with some basic terminology and a typical synth patch. What is a typical synthesis setup? What are the kinds of modules in that setup? What will we learn moving forward?
