Whilst rummaging through some of my photo’s I found a few images of my Thomas Henry 4046 VCO’s with their shiny new panel.
These were some of the first things I built when I started building a modular system.
There’s more stuff I’ve built and not posted about so as I find pictures I’ll post them here.
I think it was nearly 5 years ago when I originally built my Oakley Sound Systems TM3030 – his take on the TB-303 minus the sequencer. For many years it’s been used with the controls on a ‘temporary’ bit of perspex bolted to the PCB.
While the sound of the unit is close to the 303, it’s not a 303 – not that that bothers me. Because of this I decided to max it out with modifications. Some the classic mods to be found on the internet and some of my own design.
A few friends have asked for a demo of how it sounds so I shot this quick video for anyone daring enough to subject themselves to 8 minutes of the same pattern with a bit of knob twiddling!
Just for the sake of it here’s a series of photo’s charting the finishing off of this build.

A lot of these have been finished for quite a while but thought I’d take some pictures while my little sequencing case is unpatched. Includes both of my switch prototypes as well as one of my CGS/Serge sequencer builds.
Read more »This is a little experiment I made after reading a thread on the Muffwigglers Forum where someone put forward an idea as to how three Serge 1973 VCF’s could be connected to form the Serge VCFB filter bank.
Whether this is correct or not it sounds pretty lovely!
With this configuration you get 5 bandpass outputs along with Low and Hi pass outputs. About half way through the video there’s a fade between two mixes of outputs. Modulation and pitch control of the filter comes from a RYO Penta sequencer and a Miasma function generator providing envelope and LFO sweep. There’s also a small amount of delay added to the output.
Can you ever have enough Voltage Controlled Slopes?! These really are the modular equivalent of the swiss army knife.
There have been many modules based on the Serge Voltage controlled slope. Maths, Miasma and Befaco’s Rampage being a few.
I thought I’d build myself Ken Stone’s take on it, the CGS75 which is fairly close to the original Serge design.
