Thomas Henry VCF-1 State Variable Filter.

video upload by EdEditz

"A test and demonstration of the Thomas Henry VCF-1 State Variable VCF which I built on stripboard. It's an absolutely beautiful sounding filter with three output modes which you can use at the same time. Lowpass, Highpass and Bandpass.
In this test I did not have the 1 Volt per Octave input connected.
You can find full instructions for building this filter (and over 50 other synthesizer DIY projects) for stripboard on my website: https://www.eddybergman.com"

Is the Behringer 2600 Eurorack compatible? Let's find out...

"Doing some measurements with the scope to see how high in voltage the oscillator outputs and the filter outputs are to see if they will work with a eurorack setup. It's possible if well attenuated but watch the video to see how high the voltages can get.

MEASURING THE B-2600 AR/ADSR SPEED with an oscilloscope.


"I've always been curious at the speed of the ADSR and the AR on the Behringer 2600 so I connected my oscilloscope to it and took some measurements. I start with the Voltage Processors, then the S&H Clock Pulse and the Noise output and from there to the Envelope Generators. I made a video of it because I thought other people might be interested in this information. I hope you don't fall asleep by the sound of my voice but you have to take the rough with the smooth LOL. Enjoy!!"

Gristleizer for Modular Synthesizers - Demo (revised version).

video upload by EdEditz

"The original Gristleizer project on my website had a tiny mistake in it which has now been corrected and the Gristleizer works soooo much better now so here is the revised demo showing what you can expect from it. Of course I only demoed it with a sawtooth wave. More and different effects can be achieved with other sound sources such as the human voice or other synthesizers or a guitar even. You can find complete build instructions for this project on my website here: https://www.eddybergman.com/2021/09/g..."

Eddy Bergman 8 Step Sequencer v2.0 DEMO

video upload by EdEditz

"A demo of the new version of the 8 step sequencer I designed.
The sequencer has an Offset feature to transpose the sequence up or down 3 octaves. It can also be clocked externally. But it is a simple design so don't expect miracles from it ;)
Complete instructions for how to build this for your modular synthesizer can be found on my website: https://www.eddybergman.com"
