Happy Holidays from the studio


Quick update. Just added a couple more units of my Tonus VCF euro module adaptation of the ARP 2600 filter (4012 module) to my Reverb Store. They are now having the waterjet cut panels.

My Delta VCF module is sold out currently, I am taking this opportunity to re-visit the panel layout. I would like the jacks to be all at the bottom of the module like on the Tonus VCF. Using surface mount would make the builds go quicker as well. Hoping the Delta VCF will be available again before the year is out, we'll see. There will be a more official announcement and panel render when time comes.

Tonus VCF (X3) Filter Gets An Onslaught of CVs Eurorack Synthesizer


This being my THIRD video of my new Tonus VCF module, and therefore I must punish THREE of them, in a line up, with an onslaught of control voltages. For those living under a rock, Tonus VCF is my all-analog Eurorack adaptation of the righteous ARP 2600 filter - the early version 4012. Module #1 (left) is belting out a big ol' kick drum using self-resonance only. Module #2 (middle) is being grass fed whole grain digital bliss from the DNA Symbiotic Waves. Module #3 (right) is squeaking out stupid little astrodroid noises using only self-resonance. Varigate 4 and Beatstep Pro are micro-managing other things: Bastl Skis dual VCA, Pittsburgh Synthesizer Box, Toolbox Sample/Hold, 4MS RCD, sequential switch. All 3 filters mixed using my Infusor module. No filters were harmed in making this demo.

ARP 2600 Filter Adaptation - Tonus VCF Eurorack 4012 Module



G-Storm Electro is now on Facebook http://www.facebook.com/gstormelectro

G-Storm announces a new all-analog eurorack module, the Tonus VCF. For a long time I wanted a vintage ARP 2600 synthesizer. Then it dawned on me, all I really wanted was a faithful adaptation of the filter in my eurorack. I'm calling it the Tonus VCF on account that the Tonus ARP logo design was used on the earliest 2600s. Without any further adieu, let’s listen to the Tonus VCF in action!

Great care was taken to keep the Tonus VCF design as close to the original as possible including component selection and transistor pair matching. My modules are painstakingly hand-crafted in the USA in limited quantities. The first units are planned to be available on Reverb.com next week, but my parts suppliers are dealing w/ holiday shipping volumes this time of year. Asking price $200 USD, international shipment available. Full details and specs at Modular Grid.

Tonus VCF Module First Look [ARP 2600 4012 Filter Eurorack Adaptation]

Details are now available at Modular Grid. Yes it's real, and it's spectacular. Should be available for $200 usd in the next week or two on Reverb.com.
In my previous video I showed a breadboard circuit of a classic analog synthesizer filter. The identity of the filter was left a mystery. Today in this video I not only reveal that it is a faithful Eurorack adaptation of the 4012 module from the early ARP 2600 synthesizers, you will get a sneak peek at my hand-crafted prototype design - the Tonus VCF - and hear it in action!

I jump right in and see how the Tonus VCF sounds by sending the resonance into self-oscillation. Be warned, demonstration of resonance self-oscillation can be shrill. Then I cut the resonance and send a sawtooth to the audio input, then a square wave, then a complex digital waveform from the Pittsburgh DNA Symbiotic Waves. After that I remove the audio inputs, return to pure resonance self-oscillation, and this time send the Sawtooth into the CV input to make the filter go berserk with some Filter FM. These are the kinds of sounds the ARP 2600 was known. Last I use an LFO and Sample-Hold as CV inputs. Audio recorded direct to Tascam DR-05, no effects.

Classic Filter Module Coming Soon - Photo

In my last video post I showed a breadboard circuit of a classic filter module. I have been hard at work developing this into a Eurorack module, a photo can be seen here. More info coming soon.

Classic Synthesizer Filter Breadboard


My first video in HD 1080p! Today I am demonstrating a classic lowpass filter circuit study on a breadboard. Shrill audio alert! - Self-oscillation audio tests are performed here. All I can say at this time this circuit is not exactly Moog per se, and the self-oscillation droid sounds are another BIG clue. I run a pulse from my Pittsburgh Synth Box, sweep the frequency cutoff, then use CV modulations with an LFO and then sample/hold. I am planning a glorious eurorack module of this circuit so stay tuned.

Roland SH-01A Synthesizer EASY Tips + Tricks

Did you know the SH-01A has delay? How can you quickly restore your preferred system settings after booting? How can you sync LFO to your sequence? In just over 10 minutes I SHOW you the answers to these questions and more!

In my previous videos I gave a review and tutorial of the functions on the SH-01A. Today in this video I will show some interesting tips and tricks for getting even more from this little synth. Follow me on Twitter! http://twitter.com/gstormelectro

Roland SH-01A Synthesizer EASY Tutorial


Did you know the SH-01A has SHUFFLE? How do you change an Arpeggio to 2 Octaves? What about changing the Sequencer note scaling to something other than 16th? Like triplets! Or making the LFO speed go into audio rates?! Say whaaaaaat? Everything you wanted to know about the SH-01A, and maybe a little bit more, all in under 30 minutes.

In my previous video I gave a review/overview on the SH-01A. Today in this video I will be giving a more in-depth tutorial. This is a great synth for beginners. And this video was made just for users with little to no knowledge of synthesizers. More experienced users may want to skip ahead to topics of interest.
