045//Extraterrestrials - Moog Mother 32 & URA self-generating music

Published on Oct 4, 2019 Alastair Wilson

"A semi-self-generating patch using a Moog Mother 32 and an Ultra Random Analog module sent through a Eventide Space hall reverb and an Eventide Timefactor on Reverse setting.

Finally, I have a dedicated random source! It's a bit of a game-changer when your music is based on random modulation... For this patch I went a bit overboard and simply connected every output of the URA to something on the M32, and 045//Extraterrestrials is the result - not quite melodic, not quite atonal, but something in between.

PATCH NOTES:
The sounds present in this patch are the M32 square wave providing tuned notes, clicks from a sub-audio LFO patched into the Ext Audio input, and odd tones from the filter resonance being driven into self-oscillation.
The M32 is triggered by random gates, which also clock one of the URA's sample & hold circuits. The filter cutoff and resonance, mix between the oscillator and a square LFO, LFO rate, and some Eventide Space parameters are all randomly modulated (the Space modulated directly from the URA). The M32 envelope is a very short pluck, and the LFO triangle wave is patched to the VCA CV input, providing wavering, uncertain volume modulation.
One channel of Maths is providing a constant voltage offset for one of the inputs of the URA, but the effect is subtle at best, and so this isn't necessary - the patch can be recreated without any noticeable difference by omitting it.
