Thank you for watching.
My name is Meska of the statik collective . I've been making mostly 'dark and expérimental' music for more than ten years now, i'v learn so much online, now it's time for me to share my knoledge, my exploration and this channel is a place to talk about the tools, sound design and techniques to make music with.
i'm tattooist at day jobs and you can found my work here :

RH Electronics: How I tune the 3340 VCO

video by RH Electronics

"This is how I tune the VCO, not how 'to' tune the VCO. My method works, but there may be others.

Power supply is critical (I can't say that enough!) I recommend a -5V supply rather than the internal zener."

Introducing the RH-1 DIY Analog Synthesizer

video by RH Electronics

RH-1 Synthesizer Sound Demo

video by RH Electronics


"The RH-1 is a digitally controlled (DCO) Synth based off the Juno 106 design. It will be available as a kit to build allowing the user flexibility of a desktop unit or rack mount unit.

It’s a mono synth with programmed ‘key rollover’ if a key is held down and another pressed it will change the pitch and re trigger the envelope.


Single Digitally Controlled Oscillator, Saw + Pulse (PWM Adjustable)
Single ADSR analog envelope (AS3310)
PWM and Filter envelope mod, adjustable
External inputs for Filter and PWM summer
0 to 5 volt analog CV
12 volt digital CV
AS3372 signal processor
Envelope re-trigger on second key press
Adjustable audio out ~650mV p-p
PIC16F18344 controller running with a 4MHz crystal oscillator
Power requirements are +/- 12 volts. A standard eurorack connector will be on the PCB

This is a DIY kit, and is not being sold as a ‘product’ it is up to the end user to build and test. RH Electronics accepts no liability for any damage that may occur to the end product or any external device. It is the responsibility of the builder to provide a suitable power supply in line with the specification. All efforts have been made to stop interference with any other device, however being a kit it is not possible to test due to differences in build.
All boards and components that are suppled are RoHS certified and proof of this can be downloaded with the product files."

McBennett Sequencer with Arduino UNO

Published on May 18, 2020 Pete McBennett

"Hi everyone! I wrote some code for a basic 4-step sequencer. The tone generator is the same PWM digital oscillator from my other Arduino projects, so it has a nice thick sound. I ran it through my LDR filter, it's pretty cool sounding.

Here is the link to the code:

ARP Pro Soloist High Pass (HP) Filter Section Clone by O.Z. Hall

Published on May 14, 2020 O.Z. Hall

"I cloned the ARP Pro Soloist High Pass (HP) Filter section. The output of the high pass filter section goes straight into the 24DB/Oct Low Pass filter on the soloist.
There are 4 - 6DB/oct HP filter circuites at 4 different cutoffs. They are in parallel. The outputs are summed.
This video demonstrates each of the 4 filters in isolation. Next they filters are combined in every combination (limit two filters at a time)."

Arduino Breadboard Glitch Storm DIY Synthesizer Demonstration

Published on May 1, 2020 The sound of Non Silence

"2 x Glitch Storm Diy Synths playing together.
One is on an original Pcb and the other built on my breadboard copied from online schematics.

Original Design by the Spherical Sound Society"

"Glitch Storm is an exploratory synth that can be build and soldered even for total beginners. It produces a plethora of blips and blops ranging for chords, techno rhythms to alien soundscapes and FXs.

At its core is a Bytebeat synth but this one is interactive. You play it tuning into frequencies and soundscapes. You have four dimensions in it to explore, three ones via the knobs and a forth one via buttons, changing the equation that is playing.

The unit is able to be played as a standalone or in the context of one studio or modular.

Is quite good for pinging filters too and can enter in an easteregg mode for it to trigger gate outs for synchronizing external gear with it.

You can order the bare PCB, the Partial Kit, the Full Kit and a Build unit.

Users ordering only the PCB will have to source the rest of components and program the Arduino Nano.

The partial kit includes a PCB + a preprogrammed Arduino Nano, so the user will only have to source the rest of components.

The Full Kit has everything needed to build the synth.

There´s a github link where you can find the BOM, the schematics of the project and the compiled file for programming the Arduino Nano."

10 Electronic Project Ideas To Do Whilst In Self Isolation, Electronics/Music

Published on Mar 17, 2020 LOOK MUM NO COMPUTER

"The most important thing to do in times like these is try and stay positive while doing everything you can to help.

These projects range from cheap things to slightly more pricey and also trust on the fact that logistics services are still very much intact.

-3D printers, i don't think it will be very long until a number of open source ventilator plans will be public , and will likely involve 3d printers, so if your community does not have one. maybe look into it! Lulzbot is pretty snazzy, but there are many other options :-

-Bare Conductive :-

-Atari console and baby 10 step sequencers all it takes is a quick search on the internet to bombarded with great resources!

"The first track from my album It's Not Great played live on 5 different synthesizers I designed.

1: A synth made just out of a Teensy 3.1 Arduino board.
2. A synth made out of a Teensy 2.0 and 4 SN76489 chips.
3. A synth made out of a Teensy 2.0 and 2 POKEY chips.
4. A synth made out of a Teensy 2.0 and 1 TIA chip.
5. A synth made out of a Teensy 2.0 and 1 SID 8580 chip.

gstormelecto XaVCF Oberheim OB-Xa Eurorack Filter Module

gstormelecto XaVCF Test Filter Circuit [Audio Only Demo]

Published on Feb 16, 2020 gstormelectro

"Audio and Video by G-Storm Electro c. 2020

I've been getting requests for demos of my upcoming XaVCF module.
It will be a eurorack adaptation of the OB-Xa filter.
More info at
You know this sound from Rush Tom Sawyer and Van Halen's album 1984.
While we're all eagerly awaiting the module prototype I thought
I would share a brief sampling from a mini-lab test circuit.
A more thorough overview of the module will happen when it gets built.
So be on the lookout for that one in the near future.

The XaVCF will sound pretty far out.
We're talking about full on intergalactic blast off here.
Headphones recommended. BUT!...
Watch your levels, thick resonant sweeps ahead!
Prepare for ignition...

0:00 Classic 2-Pole resonant drop sweep
0:16 4-Pole Resonant Riser
0:41 2-Pole pure self-oscillation sweep w/ tracking
0:56 ...add both VCOs back in, slow sweep through sweet spots
1:40 2-Pole pure self-oscillation musical sequence
2:05 1-Pole Bandpass LFO modulated

VCOs: 101-VCF, Pittsburgh Synthesizer Box
LFO: Batumi
Delay: Timefactor
Sequencing/Control: Beatstep Pro
No mastering, no eq, nor additional post-effects added."

"The XaVCF is a faithful adaptation of the OB-Xa filter in Eurorack with added features.

As with the original, the XaVCF has two filter circuits to choose from! The heart of both designs having each its own Alfa reissue AS3320 chip. The XaVCF has the original Modes: a 4-Pole standard Lowpass circuit, and a 2-Pole Lowpass derived from a State-Variable circuit. Additionally there are 1-Pole Bandpass and Lowpass modes not available on the original!

Both filter circuits on the XaVCF not only have musical self-oscillating resonance w/ CV control, but the frequency cutoff can be tracked V/Oct using the CV2 input jack. In this way the XaVCF can be used as a sine wave oscillator. Unlike some older classic filter designs, the XaVCF retains a lot of low end at higher resonance.

The XaVCF is drenched in that fat and creamy wall of sound you’ll not soon forget. Are you ready for the Xa experience?

* Two selectable filter circuit configuration Types: Type I-SVF 2-Pole Lowpass, and Type II 4-Pole Lowpass.
* Additional Modes: Type I 1-Pole Bandpass, Type II 1-Pole Lowpass
* Two voltage controlled input jacks for Frequency CUTOFF w/ signal attenuators. CV1 is an extended range input capable of providing some boost to weaker control signals. The CV2 input will track V/Oct when its pot is fully CW.
* A voltage controlled input jack for RESONANCE w/ a signal attenuator CV3.
* Two audio signal input jacks w/ individual attenuators. Above midpoint, these inputs can overdrive the filter from most Eurorack oscillators and audio sources. This is especially useful in Bandpass Mode to compensate its weaker audio output signal.

Tweaking sounds on an Korg MS-20 while getting sequenced by Beatstep Pro. I'm using a little circuit that converts the eurorack standard to pitch CV and gate triggers the MS-20 can understand."
