My 33 1/3 book, on Aphex Twin's Selected Ambient Works Volume II, was the 5th bestselling book in the series in 2014. It's available at Amazon (including Kindle) and via your local bookstore. • F.A.Q.Key Tags: #saw2for33third, #sound-art, #classical, #juntoElsewhere: Twitter, SoundCloud, Instagram

In the Key of G(enerative)

The software patch as live performance

“System has decided to generate in G.” G is the key, and generative is the mode. That line is one of the many captions that illuminate the software patch in action in this video. You don’t have to fully comprehend, or even read, the text to appreciate the correlation between the virtual patch (signal flows, triggers, and such) and the sounds that emerge as the piece proceeds.

The text and patch, both by Siegfried Mueller, depict the inner workings of GenAura, Mueller’s “Generative Ambient System.” The video is almost half a decade old at this point, and the interface of the toolset, Max/MSP, in which the software was coded has come a long way since then, but the music remains nuanced and entrancing, and Mueller’s concise distillation of process is a great example of how watching a generative tool enact its own decision-making is a form of live performance.

The word “indeterminate” is often associated with generative music because chance is a key factor in many generative systems. The thing to keep in mind is that when it comes to GenAura it can be said that the music is determined — it’s just determined by the decision-making of the software itself, which of course extrapolates decisions built into the DNA of its code by Mueller.

It’s the latest piece I’ve added to my ongoing YouTube playlist of fine “Ambient Performances.” Video originally posted five years ago on YouTube by Siegfried Mueller, who developed the software.
