Nekyia Circuits are a new modular maker who’ve started out with 4 very useful modules; Obsidian is a dual complex LFO, Opal is a two channel mixer/attenuverter, Sosumi is a dual Low Pass Gate and Root Locus is a fun multimode filter. In this video I show how to use them to make great techno patches using the Bastl Pizza oscillator.

Obsidian has two triangle core LFOs but also has a min/max/diff/sum maths section that lets you generate complex modulation shapes. It also can be clocked sync’d (sort of) using a reset input, and you have CV control over the wave shapes.

Opal is a neat dual mixer or attenuverter that can mix audio or CV, and offset and attenuate it too. Very handy to combine with any LFO.

Sosumi is a dual Low Pass gate which gives a lovely plucky sound when struck, and also has CV control over the length of the gate delay.

Finally Root Locus is a two input multimode filter that allows for CV control over the input selection, CV control over the filter mode, and can go into subaudio range so you can filter LFOs or turn it into a quadrature LFO.
