Some obligatory LPG bongos with the Make Noise LxD

Posted on by
I finally picked up a Make Noise LxD to see how it compared to my trusty Optomix. What better way to test it than some traditional Low Pass Gate Bongos? The sound source is a pair of sine waves ring modulated by a Make Noise modDemix and then distorted and wave folded by the Random Source Serge Wave Multipliers. This is then high pass filtered by a randomly modulated Tip Top Forbidden Planet. The LxD has a lovely organic response and I think it sounds much better as a LPG than my Optomix.

Generative Quantussy Cells

Posted on by

An early experiment with Quantussy Cells to create purely generative music. There are 3 cells in this patch, which requires 6 Sample and Holds. I have a long way to go to tame this sort of structure, but it’s a promising line of research. It’s the first time I’ve really felt the need for some stackable cables, as it takes a lot of patching, and tapping of outputs at various points.

Logistic Canon

Posted on by

A patch which realises the logistic equation: Xn+1 = k*(Xn – Xn2), with k between 3.57 and 4.00. The resulting ‘chaotic’ CV is quantised to a Pentatonic Minor scale and then run through the Intellijel Shifty to create a three-part canon.

The logistic equation is slightly fiddly to patch, and is very sensitive to the value of k, but the resulting output seems to have a more musical quality than a random signal.

The most beautiful oscillator in Eurorack

I’m simply in love with The Verbos Complex Oscillator. Surely the most beautiful sounding VCO in all of Eurorack… and probably the best looking too. Why on earth did I wait so long? Its sound is so far beyond anything else I’ve used, and unlike many other complex VCOs it just seems to be one huge sweet spot; it’s hard to make it sound bad. Gorgeous in every way.

Here is a simple test of Amplitude Modulation, with Timbre, Harmonics, Mod Index, and Mod Osc Frequency all modulated via slow LFOs. Reverb is from a Make Noise Erbeverb
