Laurentide Synthworks VG2 Eurorack Module Kit

Laurentide Synthworks VG2 Eurorack Module - DIY Build

Laurentide Synthworks VG2

Laurentide Synthworks VG2 is a Passive Dual Vactrol Gate meaning no power is needed to get some awesome sounds out of this eurorack module!  Each Vactrol Gate on the VG2 has 1 CV Input (gate, envelope, LFO, etc.), 1 Audio Input and 1 Audio Output. The CV Input hits the Vactrol LED, allowing whatever audio to pass through. In addition, there is a simple Low Pass Filter applied to the Audio Output with an amount (i.e. Cutoff) knob. As this is a passive circuit, it will not give you full cutoff control, but it does allow the calming of brash wave shapes. There is also an LED at the CV Input for a quick visual reference of the incoming signal.

Keep in mind that a passive circuit using a vactrol can cause subtile differences in tone and output sound. One may be slightly “louder” than the other, or one might have a longer or shorter release time. One circuit could be better suited for drums or percussion while the other might process harmonies or sequences more to your liking. That being said, each vactrol or VG2 is unique in its sound.  Being that the Laurentide Synthworks VG2 is available as a DIY kit only, this gives the builder the opportunity to tweak some of the resistors and vactrols and thus making each individual build unique in itself.

During our build, we began by installing all of the supplied resistors and vactrols as recommended. As we dive more into the sound of the VG2, we might consider going back and cutting off some of the 1K resistors. It all just depends on how and what we decide to use it for in the end. The VG2 was supplied with white Davies Clone knobs, we opted to use Blood Red Davies Clone knobs to give our VG2 a more fitting look. (It matches their company logo better!). The build itself was relatively quick and to the point as we completed this module in under an hour. Laurentide Synthworks also provides some basic instructions on how and what to populate in the appropriate order via their website. We really didn’t follow the guide and just jumped right into this simple build. When it was all said and done, we popped it into one of our racks and off we went. For 49$, this kit is a must have in any Eurorack rig.

Additional Build Notes

Important Note: As this is a passive circuit, it is advisable to use a Buffered Multiple before the CV Input to maintain voltage/amplitude, especially if you are using the top CV to drive both gates. Laurentides website advises that “whatever is sent to the CV jack on the top gate is also sent to the CV jack on the bottom gate. The downside to this is there is a slight voltage drop causing the both outputs to be slightly quieter than if the CV was only driving 1 gate. If you are only using one the inputs and have something against using the bottom gate, you can plug a dummy cable into the bottom CV, or completely disable it by cutting the trace”.

Fonitronik Ps3100 Triple Vactrol Resonator – Time Lapse Build

Fonitronik Ps3100 Triple Vactrol Resonator - Time Lapse Build

In our latest build we take on the Fonitronik Ps3100 Triple Vactrol Resonator – A clone of the lovely triple resonator from the rare 1977 Korg Ps3100 polyphonic modular.

What we have here is basically a module combining three bandpass filters (vactrol based filter core from the PS3100) with a simple resettable LFO and some clever CV and signal routing.  The LFO is normalized to the common CV input, which is normalized to the 3 single CV inputs. the 3rd CV channel can be inverted.

The build itself was a timely one and it took great patience and a skillful hand to complete.  As they stated in the description “Not for the beginner”, remained true.  We don’t recommend this kit to anyone just getting started in the Eurorack DIY realm as it can easily be overwhelming and a simple soldering mistake can cause feelings of anxiety and let down. 

Now, if you successfully complete the module as we did, the module itself can be a prize possession in your rack.  The triple vactrols do exactly what they say they will do and resonate some of the warmest sounds from the 1970’s.  Hence, another reason why this module is special.  The warmth of the analog audio is something that is rare to find in today’s Eurorack systems.  

If you are down for a challenge and are needing some much provided warmth in your rack, this might just be the perfect module for you!

Fonitronik Ps3100 Triple Vactrol Resonator Specifications:

Module Description:

– 3 single audio inputs + a common audio input,

– 3 single audio outputs + sum audio output

– 3 single CV inputs with attenuators + a common CV input

– LFO output, LFO reset input

Module Dimensions:

Height – 3U

Width – 20HP

oRigiNs – Cover Art Comparison 2001 vs 2018

maKo oRigiNs old coveroRigiNs - Remastered Cover 2018

As we approached the reissue of the oRigiNs album by maKo, we decided to take a look back at the cover art and compare it to the new reissued artwork and what it will look like upon its release in 2019.  We had originally scheduled this release for October of 2018, but decided to pull the album back for some last minute tweaks in the mastering and production.

Since this audio was recorded on audio cassette circa 1994 and then issued on CD in 2001, the master files needed some heavy duty reworking.  To bring you the best sound possible, we decided to push this one back and move forward with the new maKo single titled “griNd“, as well as the remastering of his previous EPs “aNgel” and it’s b-sides “fa113_n“. These reissues will release after the single and oRigiNs will follow thereafter.

Updated Release Timeline: maKo

December 2019 – griNd

January 2019 – aNgel EP

February 2019 – fa113_n (aNgel b-sides EP)

TBD Q1 2019 – oRigiNs


Time Lapse Build: Two Tone Dual Low Pass Gate

Time Lapse Build: Two Tone Dual Low Pass Gate - Black and Gold Edition

In our latest build, we take on the custom Two Tone Dual Low Pass Gate Eurorack module. This is the new 2018 Black and Gold version released earlier this year and needless to say … it comes packed full of surprises and killer tones!

Purely customizable by the builder and with their choice of capacitors, one can simply change the sound of this LPG by swapping out the capacitors with one of their liking. Another cool thing about this module is that it’s completely passive… that’s right.. PASSIVE. We are anxious to get this into our rack and had to pick one up as soon as we heard the amazing warmth this little 3HP module provided.

Now you may be asking, what is all this LPG, VCA and Passive talk? Let us explain…

By definition, a Low Pass Gate is basically a low pass Voltage Controlled Filter (VCF) configured to act like a VCA. A VCA or Voltage Controlled Amplifier is an amplifier whose gain is set by the voltage level of a control signal. Sometimes VCA’s are called Voltage Controlled Attenuators so don’t get confused if you see them called either because they are both the same thing. Now, with regard to synths, the VCA is usually the last point that a signal goes through before being sent to the output; i.e. the VCA determines the output volume level of a played note.

With regard to the Low Pass Gate Filters (VCA’s) that is used in many West Coast Synthesis, the LPG doesn’t allow audio to pass through it when there is no control signal passing through it. Its cutoff frequency is way beyond subsonic range and well below the threshold of audio frequencies. When triggered by a control voltage, this causes the cutoff frequency to rise and allows audio to pass through. Often times Low Pass Gates used vactrols to help them mimic percussive sounds due to the short bursts of control voltage being fed to them.

In the case of the Two Tone Dual Low Pass Gate, it not only uses dual vactrols to help shape its sound, but it does this without relying on power to control the voltage passing through it. This classifies the Two Tone Dual LPG as a Passive Module, meaning “containing no source of electromotive force”.  This means you can save those precious flying bus cables for other modules that need the rest of the juice. 

Overall, this is an amazing West Coast module that has a lot packed into 3HP… and with that being said …we might have to pick up another just for fun because one can never have enough VCA’s!
