Rat King Modular TONE – DIY Build

Rat King Modular TONE - Eurorack Modular Build

Tone DIY Kit

For our first build of September, we were honored to receive one of the first Rat King Modular TONE kits from our friends over at Synthrotek

A relative newcomer to the Eurorack Modular scene, the Rat King is quickly proving to be a master of modular synths. Being the third module in the series, we have to say that the TONE module pairs well with its brethren kin; the EVENT and the Random SEQ

So, what makes the Rat King Modular TONE different from other VCOs?  Well, besides the beautiful mustard gold PCB and the matte black panel with gold laced graphics, the TONE uses the Alfa AS3340 chip (a CEM clone), made famous by its outstanding quality.  It is hard to go without saying that this VCO has some grit and some warm sounds that are trackable over an entire 8 octaves. 

Let’s get onto the build … All Hail The Rat King! 


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.
